SAAB 97X FREQUENTLY ASKED QUESTIONS

For many years oil pickup problems have cause a variety of engine problems on Saabs. Oil pressure issues, Main/Rod bearing issues, Timing chain issues etc..... We are seeing even more problems with the oil pickups getting clogged up on the 93.95 cars now that the oil replacement recommendations have increased. We are seeing more and more issues with the lower ends of the engines beginning to scream or make a high pitches whining noise due to low oil pressure to the upper end of the engine. When the timing chains are being replaced we HIGHLY recommend cleaning or replacing the oil pickup tube as well. We also do NOT recommend changing the oil at intervals that are higher than 5000.00 miles. Not everyone runs synthetic oil all the time and synthetic is not available at every store in the world.

The term ABS means ANTI-LOCK BRAKING SYSTEM. The ABS System automatically controls braking at the front wheels individually and the rear wheels as a unit (in most cases) preventing the wheels from locking during a hard braking situation. This enables the driver to maintain STEERING control and also shortens the distance to a complete stop. In cars without ABS, the brake master cylinder actually applied steady pressure to each wheel when the brakes were applied causing the wheels to look under heavy breaking. This led to wheel lockup, loss of steering control & lengthy stopping distances. ABS systems use a hydraulic pump that applies modulating pump pressure during heavy braking. The ABS system in effect pumps the brakes for the driver a consistent frequency. This pulsing is considerably faster than even the most experienced driver could accomplish if he were to attempt to this manually!

AC Compressor clutch replacements usually cost more than compressor replacements because of the cost of the clutches and the cost of the labor added together. In most cases you end up getting a compressor that is about the same cost and may not last as long as a new one. This is why we do not sell compressor clutches.

The low side port is on the largest line and the high side port is on the smallest line. Typically the high side line is the smaller of the two lines and has the highest pressure running through it.

The amount of freon needed in a Saab AC system is from 2.5lbs to 3.0lbs of freon to properly fill the system. When filling you can watch the site glass on the receiver drier or expansion valve to figure out when you have put in enough freon. Once the site glass goes from milky to clear then the system is full.

Several things can cause your AC fuse to blow when turning on the Air conditioning. The most likely cause of a Blown AC fuse is a frozen or burned up AC Compressor clutch. When this occurs the heat from the burned up compressor clutch often causes the compressor bearing to seize up and burn the AC belt off. Compressor replacement is the only repair!

In most cases AC hose failures can be determined by noting a thin oily substance at the junctions of where the AC hoses come together or at the couplings of where the hose and the alloy part of the lines come together. In many cases you may also be able to literally turn the AC hose clockwise to check for movement as well.

AC lines problems occur on any car with AC. It is primarily a weak spot in every AC system. Typically what occurs is that the lines begin to leak where the aluminum part of the lines run into the rubber line. If you grab the junction with your hand you can sometimes twist the two parts. This is a good indication that there the line crimp has let loose and the line needs to be replaced.

NOTE: If the line is leaking at the crimp you will often see a gummy substance where the leak exist.

A roaring noise that can be heard when turning on the A/C can generally be attributed to a faulty A/C Compressor but can also come from a faulty A/C idler pulley (2.0 Liter engines). Both components fail on a consistent basis on the 1985 and up 9000's. Compressor failure should be done by a professional technician only. Idler pulley failures can be identified by removing the belt and turning the idler by hand to see if the bearing has failed!

The Alarm remote communicates with a control module located under the drivers front seat. The range is typically around 25 feet depending on the type of transmitter that you have. The left button is used to arm or disarm the car. The right button is used to lock or unlock the trunk.

The battery life is about 3 years under normal use. Use the distance at which the remote functions to determine the battery strength. On the newer cars the SID unit will read "REPLACE KEY BATTERY" when the battery warning is activated by the remote. To replace the batteries simply push off the back housing by pressing downwards. On the newer remotes you may have to insert a small pin on the side of the remote housing to release the cover or remove screws on the back side of the remote. Remove the batteries and replace them. Most newer remotes are powered by a 3V lithium battey. You can buy them at radio shack. After the batteries have been changed you must press the remote 5 times in a row to re-activate the remote.

NOTE: If the remote is being replaced by a new one you will have to marry it to alarm unit by going to your local dealer and having them program it to the alarm module allready in the car.

A word about Anaerobic sealant. If you touch it on the outside then it will always be tacky because by definition the word Aenorobic means "pertaining to or caused by the absence of oxygen" this means that it will never cure until oxygen is removed. Saab began to move away from common engine gaskets in approximately 1993. They began to replace timing cover and oil pan gaskets with anaerobic sealant. These types of sealants work well on machined surfaces.

NOTE: When using these types of sealants you don't want to slide components together you want to apply sealant to both items and then apply them together. As mentioned before the outside edges of the two pieces will likely never harden.

Generally, A roaring noise during belt rotation (without the A/C on) will often be caused by an idler pulley bearing going bad. There are occasions where Alternator bearings will also create a roaring noise during belt rotation. In-order to diagnose either of these problems simply remove the belt and rotate each of the pulleys by hand. The pulley failure will make itself apparent by noting that the noise begins when rotating the faulty pulley. These pulley failures are very common on the 900, 93 & 95 cars. Keep a close eye on those pulleys because they will cause major engine damage if the car is driven after the belt comes off. The engine will begin to overheat instantly.

BELT REMOVAL SHOULD BE BY AUTHORIZED PERSONNEL ONLY! PHYSICAL INJURY CAN OCCUR!

Black dust on the rims usually comes from the type of material that the brake pads are made of. Most factory pads are made of a very soft material to prevent brake squeal. The real problem with that is softer means more dust. Harder usually means more noise. The absolute best thing we have seen to prevent dust is ceramic pads. Keep in mind that there is NO such thing as a pad that does not create dust. They all do. Some less than others. Ceramic pads seem to be the best overall combination to prevent noise and dust.

A Vibration when applying the brakes on the 9000 series can often be attributed to warped Rotors. Warped rotors can have several attributing Factors. For example, Over tightened lug nuts can cause rotors to be in a bind therefore leading to warpage during one of the next heating and cooling cycles. However, this is not say that this is the leading factor. Rotors tend to warp in general simply because of the number of times they heat up and cool during a year. When you stop suddenly or brake hard the rotors heat up and then cool back down.

Saab does not recommend turning rotors because the majority of time after turning them they are below Saabs recommended minimum thickness. The recommended minimum thickness is generally stamped on the rotors! This is not to say that Saab rotor cannot be turned. They can be turned one time but will generally warp within one year because of how thin they become!

One of two reasons. Reason 1 - The pads that were used are an inferior grade pad. Usually, an inferior grade pad will make its presence known by noting a very high pitch squeal when applying the brakes. Reason 2 - The brake pads that were used are hard use pads which contain a type of material which will cause this noise to occur. It does not mean that there is a serious problem. It simply means that it is the type of materials contained within the brake pad. Only cure - replace the pads! Hard use pads will generally not cause damage to the rotors but the noise can be somewhat consistent!

NOTE: We have also noticed that brake scrubbing sound could come from a worn wheel bearings. Although the sound is different it does sound close enough that one could confuse the two.

Bleeding the brakes can be accomplished in several ways. The most conventional way is the have someone pump the brakes and then hold the pedal to the floor. While the person holds the pedal tightly to the floor you go to the wheel closest to the brake master and release the bleeder nipple on the caliper which lets the fluid out then tighten the nipple. Repeat this process at each wheel until straight fluid comes out of each caliper nipple without any air bubbles. Be sure to fill the reservoir after bleeding each wheel. Another way to bleed the brakes is to get a hand pump that has a cap that fits the reservior, pump air into the reservoir then bleed the brakes in the same manner.

It is not uncommon to have a mushy brake pedal after doing a brake job. What typically occurs is that the air gets trapped in the lines during the piston push-back process. In most cases this mushy feel will go away with time but in extreme cases you may have to bleed the brake calipers at each wheel to get the air out.

NOTE: Most brake jobs require a break-in period after doing a brake job which will allow the need pads to seat to the new (or old) rotors. This can take from one week to two weeks.

Pulling left or right can be caused by numerous issues which include: Sticking brake calipers, faulty brakes hoses (that are swollen from within) and faulty brake master cylinders. In most cases it is caused by a sticking brake caliper. Depending on the application some calipers can be rebuilt and in other cases the faulty caliper must be replaced. If your vehicle is equipped with ABS brakes you may find that the valve body in the ABS system is malfunctioning or a proportioning valve is bad.
NOTE: ABS brakes are under VERY HIGH PRESSURE and should only be worked on by those who are properly trained!

Be very careful when replacing bulbs in the turn signals and taillights. We have seen issues when people install multi filament bulbs in single filament bulb sockets and visa-versa. One of the issues that we have seen is that the vehicle will run on when turning the ignition off or will not start at all. Keep in mind that different symptoms could occur with different cars. This may or may not apply to your particular Saab.

In Most cases faulty Converters can be identified by noting that your car will not accelerate or seems to have severely diminished power. Many times converters that are clogged up will glow red when the vehicle is running. The reason for the Glowing is because of the amount of heat and unburned fuel that collects in front of the clogged up converter. Converter replacement is the only option. A quick way to be sure that the converter is the problem when it is suspect is to disconnect the exhaust system at the header and allow the exhaust to flow without going through the converter. If the converter is the problem the cars power should be restored with the header pipe disconnected.

NOTE: There is always a cause for a clogged converter, either excess fuel from a faulty part like and ECM, Injector, wiring issue, Oxygen sensor etc....... We have seen issues with the platinum in converters breaking loose which causes a rattle but other than that converters that get clogged have to be related to a failure in the fuel system or possibly the ignition system.

The most common Exhaust failures are mufflers. You can often easily diagnose issues with the exhaust system by placing a rag or towel over the tailpipe hole (Just for a few seconds). BE CAREFUL AS THE EXHAUST MAY BE HOT!!!!! When you cover the tailpipe hole up for a few seconds pressure builds in the exhaust system and a whistling noise will begin to occur wherever your exhaust leak is.

When changing any major cooling system component on a Saab you will need to get the air out of the cooling system. In most cases there is no coolant nipple to bleed the air. The easiest way to do that is to remove the coolant reservoir cap and run the engine. Once the thermostat opens the air will cirulate through the cooling system via the waterpump circulation. Once the bubbles disappear from the coolant reservoir you can install the cap and the air should be removed.

The typical Saab cooling system holds about 1 gallon of antifreeze mixed with distilled water 50/50. This is a general rule and may be slightly different depending on the year vehicle you are servicing.

There are several common cruise control failures on Saabs. The pedal switch failures are the most common problem. What generally occurs is that the pedal switches become mis-adjusted or the ears get broken off the switches causing a no contact condition. Another common problem is that the cruise vacuum hose leading from the vacuum pump under the false bulkhead begins to crack where the vacuum fitting is located at the firewall.. The third most common failure is an intermittent functioning cruise control module. This can often be identified by noting that the cruise will work intermittently (900 & 9000 only).

Inner CV boots break (in most cases) due to dry rot or lack of grease. Outer boots generally fail to due to dry rot or in some cases excessively worn Outer CV joints cause excessive movement in the joint area placing strain on the boot causing it to break in the bend.

Electrical door component failures. What we mean here is that more than one electrical component on a door fails at the same time. For Example; window won't go up and down, door mirrors won't move, door won't unlock, central lock won't work, etc..... When this happens you will likely find that the connector where all the wiring runs to the door is either broken or just pinched. Some cars have a connector and some cars just have wires that run through a rubber grommet. Checking the wiring and repairing it should cure the problem.

In-Order to test for electrical drains on the battery you need to place a Test light between the negative battery terminal and the Actual battery cable with the two disconnected and then pull one fuse at a time until the light goes out. What ever fuse or combination of fuses that causes the light to go out will tell you where the drain is coming from. This will tell you where the problem is and you can address whatever component or relay that is causing the issue.

Cleaning the engine compartment is fine as long as several necessary precautions are taken. Be careful not to pressure was directly at the distributor or directly into the wiring harness. Don't use carb cleaner or items such as this around the harness as harsh abrasives will peal back the wire coating in the future. Try not to spray directly into the harness where water will collect and stay for long periods. If you feel that you have gotten the wiring connectors wet simply remove them and squirt a small amount of dielectric grease into them and reconnect.

Engine oil consumption is an indication that something is wrong either with an engine oil leak, internal engine ring problem or Turbo issue. The most common problem is excessive bushing clearances in the Turbo causing oil to leak into the intake manifold. Replacement of the turbo is only cure. Engine ring problem means replacement or rebuilding of the engine. External engine oil leaks would require locating the leaks and repairing them.

The most common Exhaust failures are mufflers. You can often easily diagnose issues with the exhaust system by placing a rag or towel over the tailpipe hole (Just for a few seconds). BE CAREFUL AS THE EXHAUST MAY BE HOT!!!!! When you cover the tailpipe hole up for a few seconds pressure builds in the exhaust system and a whistling noise will begin to occur wherever your exhaust leak is.

A harsh smell coming from the exhaust can usually be attributed to the use of fuel that contains methanol (Although in most places it is not supposed to be sold). When using this fuel, a sulfur smell can be emitted from the exhaust which can range from a mild odor to a rotten egg smell. To avoid this smell try changing the place where you purchase fuel! Catalytic Converter failures can also cause this same smell!

The exhaust system is designed to carry away the engine's exhaust gases with a low flow resistance, low noise level and a long operating life. The exhaust system is composed of two parts: a front part with a catalytic converter, and a rear part with two mufflers. Both mufflers are a combination of resonance and noise absorption material. The system is delivered seamless via one unit. For spare parts there are three different sections: a front section with flexible pipe, a center section with a front muffler, and a rear muffler. The exhaust system is held up by six rubber mounts from front to back. The exhaust system is protected against corrosion because of all the parts except the outer plate of the front muffler are made of 12-18% chrome steel. The outer plate of the front muffler is aluminized. This combination gives very good corrosion stability. Heat shields are fitted above the exhaust system's most heat intensive zones to protect exposed parts where the heat radiation can otherwise cause problems.

There are several ways to tell if your vehicles front-end is out of alignment. One, is that the steering wheel may appear to be of center (an indication of something bent or tie rod ends off center). Second, your car may pull to the left or right when on flat ground (an indication that the alignment is off). Third, Front tire wear is an indication that problems exist in the front-End. This could mean that the caster or camber is off and in need of adjustment.

All Saabs from the old ones to the new ones can run on all grades of fuel because the systems are designed to adjust the ignition timing according to knock in the engine. When the sensor detects a knock the ignition timing is reduced in-order to eliminate the knock. Keep in mind that running higher octane fuel generally allows for better performance especially in any AERO Saab.

Thanks to Tim Waddingham for contributing to this FAQ!

I received a letter from SAAB stating that I should not use 85 octane fuel in my 9-5. If I did use 85 octane fuel - any engine damage would not be covered under the warranty. 85 octane fuel is sold as "Regular" in higher altitude areas like Denver. 87 octane is "Mid Grade" and "Premium" is only 91 octane. We can't purchase any higher octane from a regular gas station.

Fuel pump failures often cause the engine to buck when going up hills or just quit completely. You can test the fuel pressure using a fuel pressure gauge. The pressure should about 40 PSI (approximately). The location of the pump depends on which car you have. The earlier 99, 9000 & 900 pumps are located under a board in the trunk and can be removed by removing the board and lifting out the pumps from the top of the fuel tank. On the later model 900, 93, 95, 97X the fuel pump is located in the fuel tank and the tank must be removed to replace it.

Upon applying the handbrake the force if transmitted to the handbrakes via two cables (one on earlier models but it was superceeded to the two cable setup depending on the car). Each cable runs to one rear wheel. When pulling on the lever the cable being pulled tightens the brake pad against the brake rotor/drum. The handbrake warning lamp also comes on until the arm is released.

Almost every vehicle has headlight adjusters on top and bottom of the back of each light assembly. Most dealerships and independent repair shops use headlight aimers to adjust the headlights. It can be done without aimers by adjusting the beam of light to be directly in front of the assembly and about 24 inches off the ground. You can measure this by aiming the lights at a garage wall and making the adjustments. You will find that one of the adjusters will adjust the light beam vertical and the other adjuster will adjust the light beam horizontally.
NOTE: Some headlights have levels located in the lights assemblies. These levels should be adjusted at 0 unless otherwise specified by the owners manual.

This Information Is For Replacing Halogen Bulbs Only! Not Xenon

The most common issue behind the light bulbs burning out rapidly is that the daytime running lights are turned on which means that the bulbs are on during the day as well as during the night. If your car is equipped with daytime running lights then you can have your local Saab dealer turn them of. In many cases you can also simply pull the fuse for daytime running lights and the lights will then only work when the light switch is turned on.

Thanks to Jordan Jenkins for contributing to this FAQ!

on the 1999 saab 9-3 if you remove fuse 15 the daytime running lights will be turned off and you can make it so you only have headlights at night.

The 9000 86-98, 900 1979-94, 95 2003-2007 & the 93 2003-2007 Sport Sedan you must buy the assemblies. You can however purchase the insert which is the full light excluding the housing on the back on the 9000 and 79-94 900 but those inserts have gotten so expensive that it makes more sense to purchase the assemblies. Only on the 94-98 900, 98-2003 93 & the 95 98-2003 can you replace the lense only. The insert (which is the glass & the housing it is attached to) can be replaced. Insert replacement is easy but one needs to be very careful not to break the ears of the insert off when trying to push the insert into the headlight frame. Lens (or just the glass) replacement is quite easy & is significantly cheaper. You simply remove the clips that hold the lenses to the lenses housing and replace the glass portion of the light.

The intake system is composed of an air filter, mass air flow sensor, connecting pipes/hoses, turbo unit and intercooler. The system is connected to the throttle body on the intake manifold. The air filter, which is located on the right-hand side of the engine bay, removes particles from the incoming air and also acts as an intake silencer. The mass air flow sensor provides the engine control module with continuous information on the amount of air consumed by the engine. The mass air flow sensor signals are processed by the control module, which monitors the air-fuel mixture of the incoming air.

Noise when going over bumps can often be attributed to faulty strut mount bearings. What generally occurs is that the ball bearings either fall out or get worn out which causes the weight pressure from the strut towers to pop because of excessive clearance in the bearing housing. Replacement of the strut, bearing and rubber bearing is recommended due to the amount of work required to do this job.

NOTE: We have also seen issues with worn out bushings in the suspension which cause the same type of noise. The way to test for bushings problems is to unload the suspension then then check for sloppy movement in the control arms. This is a definately indication of worn out bushings.

NOTE: Another source of the bumping noise could be worn swaybar endlinks.

Odd interior smells can come from several places. Here are a few:
- Leaking evaporators or Heater cores can cause coolant leaks to soil the carpets causing musty smells:
- Leaves in the false bulkhead under hood cause AC/Heater drains to clog causing odd interior odors.
- Clogged sunroof drians can cause water to backup and leak through the interior.

NOTE: Clogged drains can be cleaned out by accessing them through the false bulkhead (in some cases where the cabin filter is). The sunroof drains are most often located in the same place under the false bulkhead but can also be located just below the windshield glass under the hood. AC drains are typically in the right from fender well. You can clean most drains by CAREFULLY pushing a bent coat hanger up the drian to begin clearing the debris.

It is easy to strip the drain plug when changing the oil because most technicians tighten the plug way too much when putting it back in after an oil change. When the plug is stripped by someone the best thing to use when trying to get it back out is to Go to Lowes or home depot and buy a pair of pliers that have a very aggressive bite. That are usually around 12.00. This might seem like a silly suggestion but they work very well.

One of the most overlooked oil leaks is cracked valve covers. If one is not very careful when using an impact wrench on valve cover bolts they can actually crack the cover itself right around where the bolt goes into the valve cover. When this happens it can cause a very bad oil leak that is difficult to trace because the leak would only happen when the engine is running. You can usually spot the crack by looking very closely at the hole in the valve cover. If a crack exist there will usually be a little of colored line leading the bolt head. Replacement of the valve cover is the only cure.

We have seen some issues with the Central Processing Unit for the Onstar causing the hazard lights to come on and stay on. When this happens you cannot shut them off without disconnecting the battery. The problem is that water gets into the Central Processing Unit which causes this issue. There are two possible fixes. If you do NOT use Onstar then you can disconnect the two wires to the unit and the problem will go away. If you DO use onstar you will need to replace the CPU.

It appears that Onstar is going to a Digital system (instead of analog) on Jan 1st 2008. Here is why, FCC rules require that cell towers support both digital and analog signals until the end of 2007. But starting in 2008, the cell towers will no longer have to support analog so OnStar is hanging up on the 500,000 of its 4 million OnStar customers who have older analog units. Consumers with a 2003-2005 vehicles will need to update their OnStar system using an adapter that will cost approximately $200. (At this point we are not aware of an adapter for Saab but once there is one we will carry it and list it here.) Unfortunately there is no adapter available for cars prior to 2001 which means that you cannot use onstar any longer.

The most common cause of power steering noise is a fluid leak. Leaking fluid causes the pump to whine due to lack of lubrication in the pump. In most cases the whine can be fixed by locating the leak and repairing it but in cases where the pump is ran dry for extended periods the pump may have to be replaced. The lines are the the most common leak area. They usually leak where the rubber line turns into the metal line. If you can turn the two parts of the lines seperately that is where the leak will be in most cases.

In most cases the radiator drain plug is located at the bottom of the radiator on the passenger side. You will usually have to remove the plastic skid plate below the radiator to access this plug. Another way to drain the radiator and in some cases and easier way to flush the system is to pull the lower radiator hose.

Generally, A roaring noise during belt rotation (without the A/C on) will often be caused by an idler pulley bearing going bad. There are occasions where Alternator bearings will also create a roaring noise during belt rotation. In-order to diagnose either of these problems simply remove the belt and rotate each of the pulleys by hand. The pulley failure will make itself apparent by noting that the noise begins when rotating the faulty pulley.
BELT REMOVAL SHOULD BE BY AUTHORIZED PERSONNEL ONLY! PHYSICAL INJURY CAN OCCUR!

The most common thing to cause the lower seat to stop on the way back is coins in the seat track. When this happens it can cause good bit of trouble depending on the position of the seat which many cause one to have to remove the seat track to get the coin out.

Note: We have also seen power seat control modules cause the stop and go of power seats. Check the connections to the motor to see this is your issue.

Recommended service intervals really depend on what year and model that you have. The earlier 99, 900 & 9000 used the 30,000 or 60,000 intervals and in the mid to late 1990's the intervals changed to 35,000 & 65,000 intervals. In the 2000 and on era the 10,000 miles service intervals seem to be the standard. We typically recommend just changing the oil at no greater than 5,000 miles and doing major maintenance at about 30.000 mile intervals. We have developed service kits that help you get all the part without having to look them up individually.

Shocks-Struts - Trying to determine if you Shocks-struts need to be replaced can be difficult. Most of the time when the shocks get worn out you can tell by pushing down on each corner of the car. If the car bounces more than once when it returns to the rest position then it likely means that the dampering effect of the shock is worn out. This would mean that you would need to replace the shocks. Replacing them in pairs in not required but is prefered in-order to keep the dampening the same on both sides.

Springs - Most spring failures can be identified by noting that ride height has changed. If you notice that the height of the front or rear or even one corner is not correct then the likely problem is a broken/worn spring. Replacing them in pairs in not required but is prefered in-order to keep the ride height the same on both sides.

The most common problem with smoke coming from the engine compartment is a leaking valve cover gasket. The rubber gasket hardens which causes it to leak on the exhaust manifold (depending on the Saab you have). The only cure for this is to rpelace the gasket.

NOTE: When replacing the gasket you should only use sealant at the front base of the valve cover gasket.

The throttle when shut should have a very small gap which allows a little air through when idling. What generally occurs is that the throttle gets coked to a point where there is no longer a gap. When this happens it can cause the car to stall when coming to a stop or when letting off the throttle quickly. Cleaning the throttle body with carburetor cleaner and a tooth brush can cure stalling if the throttle body is dirty but vacuum leaks are the most common cause of stalling.

Thanks to scott chrismon for contributing to this FAQ!

I have noticed that if you turn the throttle body manually from under the
hood without aid of the cable, the low idle gets altered and can cause your car to idle too low causing it to stall upon take off. A quick disconnect of the battery will appearantly allow this to reset and idle correctly. Hope this helps someone. 2002 9-5 Arc 3.0 V6 wagon. I found out that my
throttle body was in limp home mode which locks the cable to the butterfly instead of the drive by wire settings . This overrides the normal settings, causing the car to idle too low and stall on take off. The Throttle Body Replacement article by the Platonoff's explains this and was very helpful in
me resetting the throttle body. One thing to note is that the CEL codes must be reset in order for throttle body to operate correctly . A quick and easy way to do this is to pull the number 17 fuse from the fuse panel, wait a few minutes then replace it and start the car. Otherwise the computer will pop the little wire on the throttle body back to limp mode and you are back where you started. Thanks for the great how too articles. I was able to change my thermostat and waterpump myself last weekend, saving me 1,300 bucks!

A whining or high pitched whirring noise that occurs at initial start up can often be attributed to a faulty starter assembly. Most of the time when starters fail you will begin to detect a funny odor coming from the starter area. The smell comes from the wires on the armature or shorting causing the epoxy on the wiring to melt within the starter.

Thanks to Rick Blake for contributing to this FAQ!

Starter noise continuing after engine starts, or a higher-pitched grinding can be caused by the ignition switch not returning to the 'Run' position. If the ignition switch binds in between the 'Start' and 'Run' positions, the starter is apparently still engaged. Another symptom to look for is that the power windows won't go up or down.

If you find that your steering causes popping when turning you might want to check the strut mounts to see if excessive play exist. Jack up the car and grab the strut with your hand. If you can move the top of the strut at all you likely have an issue with the strut bearings being worn out. If you decide to replace the strut bearings you might want to replace the struts as well.

A Wandering feeling in the steering can often be attributed to faulty tie rod ends. Tie rod ends are the components that Tie the wheels to the steering racks. When they have excessive wear they tend to cause the tight steering feel to disappear. When replacing Tie rod ends be careful to count the amount of turns that it takes to remove the ends and place the new ones on using the same amount of turns. This will insure that the tow-in remains the same.

Thanks to Steven Pfaff for contributing to this FAQ!

The tie rods also connect to the rack and pinion unit with rubber bushings that usually fail within 100,000 miles. When these bushings wear out completely, the tie rods are allowed nearly 1/2" of free play. The bushing kit costs under $20 and can be easily accessed at the center of the steering rack. Often when the bushings are worn, you can easily tell with a visual inspection.

In the event of a sunroof motor failure you can shut the sunroof manually. There is an allen key in the overhead console where the sunroof motor is located which can be inserted into the sunroof motor and turned manually to close the roof itself.

NOTE: On 1979-1994 Classic Saab the sunroof can be closed from the trunk.

Tightening torques are important in certain situations but not quite as much as most people think. In general most engine gasket torque for bolts is around 12-18 psi (not headgaskets). The truth is most bolt positions do lend to one being able to torque the bolts to the correct specifications in the first place. A general rule of thumb is that if you tighten the bolts with regulator hand wrachet and you have tightened the bolts to a point that you cannot turn the wrachet anymore then you are pretty close. The most common issue with any typical backyard technician is overtightening the bolts not undertightening. Remember to use gasket sealant only in places that seem logical to have it like corners of pans, covers etc..... We have seen issues with people overtightening valve cover & oil pan bolts and breaking the covers themselves.

Front Tires - Poor tire wear on the front tires generally come from poor alignment or lack of tire rotation. Checking the alignment and doing a 4 wheel thrust alignment can prevent tire wear but needs to be done once a year. Excessive Toe-in (tires pointing toward each other at the front or rear) or excessive Caster (tires pointing toward each other from the top or bottom) is usually the cause. Both caster and camber issues can wear tires very fast and it is common to see changes in alignment readouts due to normal tire wear.

Rear Tires - Rear tire wear almost always come from lack of rotation which causes cupping (uneven wear patterns that can be felt when you run your hand down the face of the tire). However, a bent rear axle or very soft tire tread can cause the rear tires to wear on the outside edges. Saabs have had issues for years with strange rear tire wear. The primary reason for this is because the rear axle is a stationary axle not an independant rear suspension. Load considerations in the trunk, etc... can also cause strange rear tire wear. Rear axle shims (depending on the car) use to be available to allow for rear axle adjustments but most are no longer available for purchase.

TCS (Traction Control System) is an anti-slip function which provides improved traction for your vehicle. The control module will reduce engine torque and control braking power to each wheel if the TCS is activated. When one of the front wheels rotates faster than the rear wheels, the TCS senses wheel spin. The magnitude of this wheel spin and the speed of the car are decisive to how the system operates. Traction is given priority when wheel spin exceeds a limit value when the speed is lower than 35 MPH. The system then employs brake application first and then engine torque limitation. The transfer of lateral forces to maintain steering ability is given priority when wheel spin exceeds a limit value at speeds above 35 MPH. The system employs engine torque limitation first & then moves to the deduction of wheel spin. A degree of wheel spin is always allowed so that the sporty feel and handling of the car remains. How aggressively the car is being driven will determine how much influence the traction control devices employ

Purchasing a used Saab can be a coin toss. Reality is that Saabs are very good cars as long as they are taken care of correctly. More often than not people who purchase high end cars just can't afford them regardless of who makes them. Above all things the number one thing to look for is whether or not the individual changed the oil at 5000 miles MAX. We know that some of the recommended service intervals are 10,000 miles but we have seen so many engine issues because of this that we flag any oil changes longer than 5000 miles. Everyone says that oil can last 15,000 miles etc... That may be true but not every car is designed with the type of oil change interval in mind. Most cars have exhaust components right below the engine oil pan which basically cooks the oil in the pan. This heat alone can be catastrophic to the life of engine oil or transmission fluid. You can pull the dipstick out and look at it closely. If it is very dark color (brown) at the base of the dipstick then that is a good indication that the heat has gotten to the dipstick enough that it has baked the oil in the lower part of the engine as well.
You can count on having some issues with Saab ie.... DI Cassettes, Belt pulley issues, Fan speed resistors, SID unit failures etc.. but in the grand scheme of things they are excellent automobiles if maintained correctly.

Not all Saabs use small vacuum hoses all over the engine but on the cars that do the hose diameter is usually 5/32. It is silicone hose that can be purchased at any autoparts store. The reason we do not sell it on the site is because the hose is usually sold in 100 ft rolls. Most customers would not want to buy that much hose. Keep in mind that there are different grade hose and the fuel grade hose is what is recommended.

Washer pump failures are typically caused by debri that gets into the washer tank and gets pulled into the pump when turning on the washer squirters. We have seen tons of issues with both the washer pumps failing and the valves that protect the pump as well. You can test the pump by removing the hose from the pump and pulling the handle to activate the washer squirters. If water squirts then the pump is good, if not you can test it further by removing the pump and applying voltage directly to the pump to be sure it works.

It is common to see water coming out of the tailpipe in the morning. Most of time water accumulates in the exhaust system due to the difference in the exhaust to air temperature that occurs overnight. This condensation is common and only happens upon initial startup. The only time to be concerned about that water coming out of the tail pipe is when the water begins to have a sweet smell. A strong sweet smell is an indication that there is a headgasket issue causing coolant to leak into the combustion chamber which then gets burned on startup. This burning of the coolant creates a sweet smell that goes away within a few minutes (once it is all burned out of the cylinder where the leak occurs). In most cases you can determine which cylinder the leak is in by removing the spark plug and looking down into the cylinder. If the piston is silver and not black then that is a good indication that the steam created by the coolant being burned is actually cleaning the black carbon (created from burned fuel) from the piston top. If you see this then there is definately a problem with coolant leaking into the combustion chamber of that one cylinder.
