How To Check Power Steering Fluid:
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.

What to Add:
Refer to the Maintenance Schedule to determine what kind of fluid to use.
See “Recommended Fluids and Lubricants” in the Index.
NOTICE I
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.

ProCarManuals.com

After work is done on the brake hydraulic system, make sure t\
he levels are
above
MIN and below the top of each window.
What To Add:
When you do need brake fluid, use only DOT-3 brake fluid-such \
as Delco
Supreme 11
@ (GM Part No. 1052535). Use new brake fluid from a sealed
container only.
NOTICE
DOT-5 silicone brake fluid can damage your vehicle. Don’t use it.
Don’t let someone put in the wrong kind of fluid. For example, just a
few drops
of mineral-based oil, such as engine oil, in your brake
-]stem can damaae brake svstem parts
so badlv that 1 fll have to
be replaced.
Brake fluid can damage paint, so be careful nor IO spit1 Drake fluid on
your vehicle.
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 flui\
d level
or adding fluid.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its many parts have to
be of top quality and work well together
if the vehicle is to have really good
braking. Vehicles we design and test have top-quality
GM brake parts in
them, as your vehicle does when
it is new. When you replace parts of your
braking system-for example, when your brake linings wear down and you
have to have new ones put in-be sure you get new genuine
GM
replacement parts. If you don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change, for the\
worse. The
braking performance you’ve come to expect can change in many other ways
if someone puts in the wrong replacement brake parts.

Scheduled Maintenance Services
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 lnspectiont -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. (On vehicles equipped wit\
h manual
steering gear, check for seal leakage.) Lubricate the steering linkage.
Accelerator Control System -Lubricate all pivot points with engine oil,
except the
TBI throttle shaft. Remove all external deposits from the injector
pump face cam on 6.2L and 6.5L engines.
Do this when the engine is cold
and not running.
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 fluid level and add as needed.
Check constant velocity joints and axle seals for leaking.
Transfer Case (four-wheel drive) lnspectiont -Every 12 months or at oil
change intervals, check front axle and transfer case and add l\
ubricant when
necessary. Oil the control lever pivot point and all exposed control linkage. \
Check vent hose at transfer case for kinks and proper installa\
tion. More
frequent lubrication may be required on heavy-duty
or off-road use.
tA fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
