Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless
you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine cotnparttnent 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 he at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up
to the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” 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 tetnperature
may
fill1 below freezing, use a fluid that has sufficient
protection against freezing.

Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full.

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, 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.

Brakes
Brake Fluid
Your brake master cylinder
reservoir
is here. It is filled
I with DOT-3 brake fluid.
There are
only two reasons why the brake fluid level in the
reservoir might go down. The first is that
the brake fluid
goes down to an acceptable level during normal brake lining wear. When new linings are put
in, the fluid level
goes back
up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak
means that sooner or later your
brakes
won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding
brake fluid won’t correct a leak. If you add fluid
when your linings are worn, then you’ll have
too much
fluid
when you get new brake linings. You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
A CAUTION0
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the engine
is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work
is done on the brake
hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections”
in the Index.

Checking Brake 1
You can check the brake fluid without taking off the cap.
Just look at
the window on the brake fluid reservoir. The
fluid level should be above MIN. If it isn't, have your
brake system checked to see if there is a leak. After
work
is done on the brake hydraulic system,
make sure the level is above
MIN and below the top
of the window.
What to 1
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, and always clean the brake fluid
reservoir cap before removing
it.
I I
I A CAUTION: I
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at
all. This could cause a
crash. Always use the proper brake fluid.

NOTICE:

Using the wrong fluid can badly damage
brake system parts. For example,.just a few
drops of mineral-based oil, such
as engine
oil,
in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake
fluid on your vehicle.
If you do, wash it
off immediately. See &‘Appearance Care”
in
the Index.
Brake Wear
If you have a C 3500 HD model, it has four-wheel
disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the brake
pads are worn and
new pads are needed. The sound
may come and
go or be heard all the time your vehicle
is moving (except when you are pushing on the brake
pedal firmly).
A’ CAUTION:
I
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your vehicle serviced.

NOTICE: .
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Free movement
of brake calipers and properly torqued
wheel nuts
are necessary to help prevent brake
pulsation. When tires
are rotated, inspect.brake calipers
for movement, brake pads for wear, and evenly torque
wheel nuts in the proper sequence
to GM specifications.
If you have rear drum brakes, they don’t have wear
indicators, but
if you ever hear a rear brake rubbing
noise, have the rear brake linings inspected.
Also, the
rear brake drums should be remoQed and inspected each
time the tires are removed for rotation or changing.
When you have the front brakes replaced, have the rear
brakes inspected,
too. I
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
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 brhke linings wear do.wn and you have
to
haye 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.

Battery
Every new vehicle has 21 Delco Freedom@ battery. You
never have
to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days
or more, take
off the black, negative (-) cable from
the battery. This
will help keep your battery from
runnine down.
I A CAUTION:
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see ”Theft-De-terrent
Feature”
in the Index.
Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are
off and the engine isn’t running. See “Replacement
Bulbs”
in the Index for the proper types of bulbs to use.
Halogen Bulbs
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around a battery without getting hurt.
-A i
F-
Halogen bulbs have prc-arized gas inside and
can burst
if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
