mounting bolts (arrows), and then turn adjusting nut (A).
To reduce the chance of drive belt failure while driving, replacement of the belts every four years is recommended.
Loosen the mounting and be~ adjusting bolts and adjust until
the belt tension is as loose as possible, then remove the belt
by slipping it over the pulleys. In some cases it may be necessary to remove one drive belt to get to another. Cross section
and length determine belt size. Use the old belt for comparison, or make sure that the new belt fits into the pulley groove
as shown in Fig. 10.
NOTE
When belts are replaced with new ones, keep the old set in
the luggage compartment by the spare tire for emergency
use.

and excess play, for example. When installing the new belt,
gently pry it overthe pulleys. Too much force may damage the
belt orthe accessory. Tension the belt(s), run the engine for a
few minutes (at least 1500 rpm), then recheck the belt tension.
Use a 5/8 in. spark plug socket to remove spark plugs. See
Fig. 12. The correct spark plugs for the different engines covered by this manual are listed in Table d. Use a spark plug gap
gauge to check the gap. If necessary, bend the outer electrode slightly to adjust the gap to meet the specification. Do
not bend or file the center electrode. See Fig. 13.
CAUTION
Do not overtighten the drive belts. Overtightening will cause
the bearings to fail prematurely.
Distributor Cap, Rotor, and Spark Plugs
The distributor cap, the rotor, and the spark plug wires deliver a high-voltage spark to the spark plugs. See Fig. 11. They
are subject to insulation breakdown, corrosion fouling, and
electrode wear and damage. The cap, rotor and spark plugs
should be replaced at the specified intervals to ensure maximum ignition system efficiency. There is no replacement intervals for spark plug wires, but they should be periodically
tested and inspected. Guidelines for visual inspection and
testing, and instructions for distributor cap and rotor replacement are found in 340 Ignition System.

Ignition timing should be checked every 60,000 miles on all
cars with distributor-mounted Hall sensors. See 340 Ignition
System for Hall sensor applications and procedures for
checking and adjusting ignition timing. It is not necessary to
check/adjust ignition timing on cars with a crankshaft-mounted Hall sensor.

On all cars covered by this manual, the idle speed is electronically controlled by the Automatic Idle Control (AIC) System. On cars with LH 2.2 Fuel Injection, the idle speed should
be checked and adjusted through the AIC system at the specified mileage interval as described in 240 Fuel Injection.
NOTE
It is not necessary to check the idle speed on cars with LH 2.4
or LH 2.4.2 Fuel Injection, as the idle speed is fully adaptive
(self-correcting) through the LH control unit.
On cars with LH 2.2 Fuel injection and automatic transmission, a mechanical deceleration dashpot is mounted to the
throttle housing to hold the throttle open for a short period
when the throttle is quickly closed. The dashpot plunger
should be adjusted to touch the throttle lever at a specified engine speed. See 240 Fuel Injection for dashpot adjustment
procedures and specifications.
Turbo Overpressure Safety Switch
(1985-1998 Turbo models)
The turbo overpressure safety switch turns the fuel pump
off when the manifold pressure reaches a higher than normal
level. This is a safety feature in the event the turbocharger
wastegate malfunctions. Checking the switch requires a
hand-held pressure/vacuum pump and an accurate pressure
gauge. This procedure is described in detail in 234 Fuel
Pump and Fuel Tank.
110-11
Oxygen Sensor
The oxygen sensor monitors engine combustion efficiency
by measuring the oxygen content of the exhaust gasses. That
information in turn is used to control the fuel injection system
and reduce exhaust emissions. Any problems with the oxygen
sensor will directly affect exhaust emissions and the way the
engine runs.
Replacement of the oxygen sensor at the specified interval
ensures that the engine and emission control system will continue to operate as designed. The sensor is mounted in the
front exhaust pipe, ahead of the catalytic convertor.
NOTE
On 1991 and later models, there is no recommended replacement interval for the oxygen sensor. When the sensor is no
longer operating correctly the Check Engine light will come on
signaling the need for the sensor's replacement.
The sensor is threaded into place and has wires extending
from the tip. Trace the sensor wiring back from the sensor and
disconnect the electrical connector. When installing a new
sensor, apply a light coat of anti-seize compound to the sensor threads. Torque the sensor and reconnect the wiring.
Tightening torque
• oxygen sensor to exhaust pipe .... 40 Nm (30 ft-Ib)
CAUTION
Do not get any anti-seize compound on the sensor tip or in the
sensor slits. The anti-seize compound will quickly foul the sensor element and render the sensor inoperative.
NOTE
Special sockets for replacing the oxygen sensor are available
from most automotive parts stores to allow the sensor to be installed without damaging the wiring.
Crankcase Ventilation and Vacuum Hoses
The rubber vacuum hoses for the crankcase ventilation
system should be carefully inspected for cracks or deterioration. Gently bend the hoses at all connecting points to check
for cracks. Fig. 14 shows a typical hose routing diagram.

NOTE
On 1991 and later models, there is no recommended replacement interval for the charcoal canister.
Fuel System
A fuel system safety inspection should be made at the specified mileage intervals listed in the maintenance program tables given earlier. Inspect the fuel tank, fuel lines and hoses,
and fuel system for damage or leaks. If fuel odors are detected
in the passenger compartment, the fuel pump seal (beneath
the luggage compartment) may be faulty. Also check the
ELCD vapor hoses that run overhead through the headliner.
See 234 Fuel Tank and Fuel Pump for replacement of the
fuel pump seal. Inspect all electrical connections for corrosion
or damage or loose connections.

Fuel Filter
Exhaust System
Because of varying quality of gasoline, the fuel filter may
become contaminated or clogged enough to restrict fuel flow.
To prevent any such problems, and to guarantee continued
good performance, the filter should be replaced every 30,000
miles. The fuel filter is located beneath the right rear of the car,
just in front of the gas tank.
Scheduled maintenance of the exhaust system is limited to
inspection. Check for restrictions due to dents or kinks. Check
for weakness or perforation due to rust. Check to see that ali
the hangers are in place and properly supporting the system
and that the system does not strike the body. Alignment of the
system and the location of the hangers are described in 252
Exhaust System.
When replacing the fuel filter, disconnect the battery negative (-) cable and clamp the filter inlet and outlet hoses to lessen fuel spillage. Loosen the center mounting bracket and the
two banjo fittings on either end of the filter. See Fig. 17. Note
the arrow or markings indicating direction of IIow on the new
filter. Install the filter and using new sealing washers at the
banjo fitting.
WARNING
Fuel will be expelled when the filter is removed. Do not smoke
or work near heaters or other fire hazards. Keep a fire extinguisher handy.
Exhaust system life varies widely according to driving habits and environmental conditions. If short-distance driving predominates, the moisture and condensation in the system will
not fully dry out. This will lead to early corrosion damage and
more frequent replacement.
ELECTRICAL SYSTEM AND
BATTERY SERVICE
Electrical System Functional Check
CAUTION
Clean thoroughly around the filter connections before removing them, and make sure that no dirt gets into the fuel lines.
Electrical system service includes checking that all electrical components, including interior and exterior lighting, are
working correctly. Replace any faulty bulbs found. If more involved electrical work is required, refer to 3 ELECTRICAL
SYSTEM for system troubleshooting and wiring diagrams.
Battery Service
Battery maintenance includes keeping the battery and terminals clean and keeping the connections tight. See Fig. 18.
Even a thin layer of dust containing conductive acid salts can
cause the battery to slowly discharge. Inspect the battery cables for chafing and deterioration of the insulation caused by
high heat. For a more detailed discussion of the battery, including testing and charging, see 311 Battery.

Maintenance Program
To remove battery corrosion, begin by disconnecting the
cables. Disconnect the negative (-) cable 'first. Clean the terminal posts and the cable clamps with a wire brush. Clean the
main chassis ground terminal on the opposite end of the negative (-) cable.
Corrosion can be washed away with a baking soda and water solution that will neutralize the acid. Apply the solution
carefully, though, since it will also neutralize the acid inside
the battery. Avoid getting the solution into the battery cells
through vent holes. Reconnect the cable clamps, positive (+)
cable first. Lightly coat the outsides of the terminals, hold
down screw, and clamps with petroleum jelly, grease, or a
commercial battery terminal corrosion inhibitor.
CAUTION
Extreme cleanliness is important when working on the automatic transmission. Use lint-free rags to check the level, and
use a clean funnel when adding lluid.
The location of the dipstick for checking the ATF is shown in
Fig. 19. The area between the MIN mark and the MAX mark
on the dipstick represents approximately 1 pint (1/2 liter) of
ATF.
WARNING
Battery acid is extremely dangerous. Take care to keep it from
contacting eyes, skin, or clothing. Wear eye protection. Extinguish all smoking materials and do not work near any open
flames.
CAUTION
Disconnecting the battery cables with the engine running, or
reconnecting the cables to the incorrect posts will damage the
electrical system.
Battery electrolyte should be maintained at the correct level
just above the battery plates and their separators. The correct
level is approximately 5 mm (1/4 in.) above the top of battery
plates or to the top of the indicator marks (if applicable). The
battery plates and the indicator marks can be seen once the
filler caps are removed. If the electrolyte level is low, replenish
it by adding distilled water only.
Fig. 19. ATF dipstick location (arrow).
The ATF level should be checked with the car on a level surface with the engine idling and the transmission fully warmed.
Firmly set the parking brake and place the transmission selector lever in park or neutral and remove the ATF dipstick. The
ATF level is correct if it is between the MIN and MAX marks.
See Fig. 20.
TRANSMISSION SERVICE
NOTE
Automatic Transmission
Many automatic transmission problems can be traced to an
incorrect fluid level, incorrect type of fluid, a clogged ATF filter,
or contaminated t1uid. With regular preventative maintenance,
expensive and unnecessary automatic transmission repair
may be avoided.
Before checking the ATF level, inspect for leaks. ATF leaks
are most likely to be seen around the ATF oil pan gaskets.
Leaks should be promptly corrected to avoid costly repairs. If
necessary, replace a leaky ATF oil pan gasket as described in
472 Automatic Transmission Seals and Gaskets.
Driving the car for five to ten minutes around town, or approximately 12 miles (20 km) on the highway will ensure a fully
wanned transmission.
If the level is too low, use a clean funnel to add ATF through
the dipstick/tiller tube until the fluid level is correct.
Automatic Transmission Fluid (ATF)
• Ford Specification M2C-33F (alternate: Ford Specification G)
Check the condition of the ATF by rubbing some between
your fingers and sniffing it. The ATF should not be foamy, gritty, or have a burnt odor. Contaminated ATF should be drained

NOTE
Because ATF is a redlbrown color that discolors to black/brown during normal use, ATF color may not be a good indicator of its condition.
To replace ATF and clean ATF filter
The ATF should be changed and the filter cleaned every
30,000 miles under normal conditions. If the car is operated
under severe service conditions of trailer towing, extensive
city driving or driving in hot climates Saab recommends that
the fluid be changed every 15,000 miles.

Automatic Transmission Final Drive
The final drive on cars with automatic transmission is lubricated with a separate gear oil. Final drive service consists of
checking the gear oil level and inspecting for leaks.
The final drive gear oil level should be checked regularly, although there is no specified replacement interval specified by
Saab. The final drive oil drain plug is shown earlier in Fig. 20.
Manual Transmission
Manual transmission service consists of checking the gear
oil level and inspecting for leaks. The gear oil level should be
checked regularly, although there is no specified replacement
interval specified by Saab. In addition, 1990 and later models
do not have a drain plug. Two types of manual transmission oil
dipsticks are used on the cars covered by this manual.
On 1985 through 1990 models, the dipstick is similar to the
engine oil dipstick. See Fig. 25. On 1991 and later cars, the
manual transmission oil dipstick is shown in Fig. 26.
Check the lubricant level with the car level. Remove the oil

Routine maintenance of the brake system includes maintaining an adequate level of brake fluid in the reservoir, checking brake pads for wear, checking hand brake function, and
inspecting the system for fluid leaks or other damage.
WARNING
• Friction materials such as brake linings may contain asbestos fibers. Do not create dust by grinding, sanding, or cleaning
the pads with compressed air. Avoid breathing asbestos fibers and asbestos dust, as it may result in serious diseases
such as asbestosis and cancer, or in death.
• Brake fluid is poisonous. Do not siphon brake fluid by mouth.
Wear gloves when working with brake fluid or brake pads to
prevent contamination of cuts.
The level of the brake fluid will drop slightly as the brakes

To inspect brake hoses, gently bend them to check for
cracks. Checkthat all hoses are correctly routed to avoid chafing or kinking. Inspect the unions and the brake calipers for
signs of fluid leaks. Inspect the lines for corrosion, dents, or
other damage. Replace faulty hoses or lines and bleed the
brake system as described in 520 Brake Fluid and Brake
Bleeding.
WARNING
Incorrect installation or overtightening hoses, lines, and
unions may cause chafing or leakage. This can lead to partial
or complete brake system failure.
Brake pad thickness should be regularly checked. Brake
pad thickness can be inspected by looking through an opening in the caliper after removing the wheel. See Fig. 29. For information on replacing worn pads, see 517 Brake Pads.
Parking Brake
The parking brake system is independent of the main braking system and does not require any periodic adjustment, although the function of the parking brake should be checked
regularly. Check that the cable moves freely in its housing. A
complete description of the parking brake is described in 551
Parking Brake.
Power Steering Fluid
The only maintenance of the power steering system is to
check the power steering fluid and add as necessary. The
power steering fluid level can be easily checked through the
translucent reservoir on the right side wheel housing in the engine compartment. See Fig. 30. When the car is at normal operating temperature, the fluid level should be between the
HOT and COLD marks. If the level is checked when the car is
cold, it should be between the COLD mark and the ADD mark.
