6-27 How to Check Power Steering Fluid
When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then 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. If
necessary, add only enough fluid to bring the level up to
the mark.

When the engine
compartment is hot, the
level should be at the
HOT mark.

When the engine
compartment is cool, the
level should be at the
FULL COLD mark.
What to Use
To determine what kind of fluid to use, see
ªRecommended Fluids and Lubricantsº in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.

6-28 Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full.
NOTICE:

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
three
-quarters full when it's very cold. This
allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.

Don't use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.

Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon Ami

Powder (non-scratching
glass cleaning powder), GM Part No. 1050011. The
windshield is clean if beads do not form when you rinse
it with water.
If you use a glass treatment or conditioner containing
ethyl alcohol or ethyl sulfate on your glass, be sure to
remove the acrylic roof panel, if so equipped. These
products may damage the panel.
Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked in full
-strength
windshield washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See ªRecommended
Fluids and Lubricantsº in the Index.)
Cleaning a Removable Roof Panel
Special care is necessary when cleaning, removing
and/or storing the roof panel.

Flush with water to remove dust and dirt, then dry
the panel.

Clean the panel with GM Glass Cleaner. Leave the
cleaner on the panel for one minute, then wipe the
panel with a soft, lint
-free cloth.

Don't use abrasive cleaning materials.
