GMC 2007 Savana - Manual (Page 319)

Notice:
• When using concentrated washer fluid,
follow the manufacturer’s instructions
for adding water.
• Do not 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 does not clean as well
as washer fluid.
• Fill your washer fluid tank only
three-quarters full when it is very cold. This
allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.
• Do not 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
on page 296 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. 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 will not work well, or
will not work at all.
