Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches
a preset temperature.
When you replace your thermostat, an AC@ thermostat
is recommended.
Power Steering Fluid
p .w ii
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with
a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
The level should be at the FULL COLD mark. Add
enough fluid to bring the level up to the mark.
A fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants”
in the Index.
I NOTICE:
When adding power steering fluid or making a
complete fluid change, always use the proper
fluid. Failure to use the proper fluid can cause
leaks and damage hoses and seals.

At Least Twice a Year Starter Switch
Hydraulic Clutch System Inspection
Check the fluid level in the clutch reservoir. See
“Hydraulic Clutch Fluid”
in the Index. A fluid loss in
this system could indicate a problem. Have the system
inspected and repaired at once.
At Least Once a Year
Key Lock Cylinders
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
Body Lubrication
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, trunk lid,
glove box door and console door. Part
D tells you what

Before you start, be sure you have enough room
around the vehicle.
Firmly apply both the parlung brake (see “Parking
Brake”
in the Index if necessary) and the regular brake.
NOTE:
Do not use the accelerator pedal, and be
ready to turn off the engine immediately
if it starts.
On automatic transaxle vehicles, try to start the
engine
in each gear. The starter should work only in
PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transaxle vehicles, put
the shift lever in
NEUTRAL (N), push the clutch down halfway and
try to start the engine. The starter should work only
when the clutch is pushed down all the way to the
floor.
If the starter works when the clutch isn’t
pushed all the way down, your vehicle needs service.

Before you start, be sure you have enough room around
the vehicle. It should be parked on a level surface.
Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary).
NOTE: Be ready to apply the regular brake
immediately
if the vehicle begins to move.
With the engine
off, turn the key to the RUN position,
but don’t start the engine. Without applying the regular
brake,
try to move the shift lever out of PARK (P) with
normal effort. If the shift lever moves out of PARK
(P), your vehicle’s BTSI needs service.
Steering Column Lock
While parked, and with the parking brake set, try to turn
the key to LOCK in each shift lever position.
With an automatic transaxle, the key should turn to
LOCK only when the shift lever is in PARK (P).
0 With a manual transaxle, the key should turn to
LOCK
only when the shift lever is in REVERSE (R).
On vehicles with a key release button, try to turn the key
to LOCK without pressing the button. The key should
turn to LOCK only with the key button depressed.
On all vehicles, the key should come
out only in LOCK.

Parking Brake and Automatic Transaxle PARK (P)
Mechanism Check
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
To check the parking brake: With the engine running
and transaxle in NEUTRAL
(N), slowly remove foot
pressure from the regular brake pedal.
Do this until
the vehicle
is held by the parking brake only.
Shift to PARK
(P). Then release all brakes.
To check the PARK (P) mechanism’s holding ability:
Underbody Flushing
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.
7-39

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice
a year (for instance, each
spring and fall). You should
let your GM retailer’s
service department or other qualified service center do
these jobs. Make sure any necessary repairs are
completed at once.
Restraint Systems
Now and then, make sure all your belts, buckles, latch
plates, retractors, anchorages and reminder systems are
working properly. Look for any
loose parts or damage.
If you see anything that might keep a restraint system
from doing its job, have it repaired.
Steering, Suspension and Front-Wheel-Drive
Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear, or lack of lubrication. Inspect the power steering
lines
and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body near
the exhaust system. Look for broken, damaged, missing or
out-of-position parts
as well as open seams, holes, loose
connections, or other conditions which could cause a heat
build-up in the floor pan or could
let exhaust fumes into
the vehicle. See “Engine Exhaust” in the Index.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding, and
for damaged or missing parts. Replace parts as needed.
Accelerator and cruise control cables should not be
lubricated.
Manual Transaxle
Check the transaxle fluid level; add if needed. See
“Manual Transaxle”
in the Index. A fluid loss may
indicate
a problem. Check the system and repair if needed.
Brake System Inspection
Inspect the complete system. Inspect brake lines and hoses
for proper hookup, binding, leaks, cracks, chafing, etc.
Inspect disc brake pads for wear and rotors for surface
condition.
Also inspect drum brake linings for wear and
cracks. Inspect other brake parts, including drums, wheel
cylinders, calipers, parking brake, etc. The parking brake is self-adjusting and
no manual adjustment is required. You
may need to have your brakes inspected more often if your
driving habits or conditions result
in frequent braking.
