Brake Fluid - GMC Sierra 3500HD 2001 Owner's Manual

Open the cap labeled WASHER FLUID ONLY.
Add washer fluid until the tank is full.
NOTICE:
D
When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.
D
Don't mix water with ready
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.
D
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.
D
Don't use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.

Brakes

Brake Fluid

Your brake master cylinder reservoir is filled with
-
DOT 3 brake fluid. See "Engine Compartment
Overview" in the Index for the location of the reservoir.
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.
