How To Check Power Steering Fluid
l
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.
0 When the engine
compartment is
hot, the level
should
be at the
FULL mark.
When the engine
compartment is
cool, the
level
should be at the
FULL COLD
mark.
Whaf fo Add
Refer to the Maintenance Schedule to determine what kind of fluid to use.
See “Recommended Fluids and Lubricants” in the Index.
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.

Hydro-Boost Brake System (Hydraulic Pump)
The power steering pump is also used as the Hydro-boost pump. Refer to
“Power Steering System” in this section when checking fluid level
or
adding fluid.
Windshield Washer Fluid
To Add
Open the cap labeled
“WASHER
FLUID
ONLY.” Add washer
fluid until the bottle is
full.
~ NOTICE:
0 When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
Don’t mix water with ready-to-use washer fluid. Water can
cause the solution to freeze and damage your washer fluid
tank and other parts of the washer system. Also, water
doesn’t clean as well
as washer fluid.
Fill your washer fluid tank only 3/4 full when it’s very cold.
This allows for expansion, which could damage the tank
if it is
completely full.
Don’t use radiator antifreeze in your windshield washer. It
can damage your washer system and paint.

Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is too heavy, the circuit breaker
opens and closes. This protects the circuit until the current load returns to
normal or the problem is fixed
.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse is near the junction block. See
“Trailer Wiring Harness” in the Index for more information.
Fuse Block
The fuse block is
behind an access door
at the bottom
of the
instrument panel, next
to the parking brake
release lever.
You can remove fuses
with a fuse extractor,
if you have one.
To remove fuses if you don’t have one, hold the end of the fuse between
your thumb and index finger and pull straight out.
Be sure to use the correct fuse. If
you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. Just pick

Lap and Shoulder Belts Condition and Operation - Inspect belt system,
including webbing, buckles, latch plates, retractors, guide loops\
and
anchors. Have
a belt assembly replaced if the webbing has been cut or
otherwise damaged.
Body Lubrication Service - Lubricate all body door hinges with engine
oil.
Also lubricate the tailgate, tailgate handle pivot points, and tailgate
mounted spare tire carrier (if equipped). Lubricate the body hood,
fuel door
and rear compartment hinges, latches and locks including interior glove box
and console doors, and any folding seat hardware. Lubricate the hood safety
lever pivot and prop rod pivot. More frequent lubrication may be required
when exposed to
a corrosive environment.
Periodic Maintenance Inspections - Listed below are inspections and
services which should be performed at least twice
a year (for instance each
spring or fall). You should let your
GM dealer’s service department or other
qualified service center do
these jobs. Make sure any necessary repairs are
completed at once.
Steering and Suspension Inspection? - Inspect front and rear suspension
and steering system for damaged, loose or missing parts, signs
of wear or
lack of lubrication. Inspect power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Lubricate the steering linkage.
Accelerator Control System - On gasoline engines, lubricate the pivot at
the
TBI throttle lever stud with engine oil. Do not oil any accelerator or
cruise control cables. Replace any cables that have high effort or excessive
wear.
Exhaust System Inspection - Inspect the complete system including the
three-way catalytic converter. 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 buildup
in the floor pan or could let exhaust fumes seep into the
passenger compartments.
Drive Axle Service? - Check readfront axle tluid level and add as needed,
Check constant velocity joints and axle seals for leaking.
Transfer Case (Four-wheel Drive) Inspection+ - Every 12 months or at
oil change intervals, check front axle and transfer case and add lubricant
when necessary. Oil the control lever pivot point and all exposed control
linkage. Check
vent hose at transfer case for kinks and proper installation.
More frequent lubrication may be required on heavy-duty or off-road use.
?A fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
