Windshield Washer Fluid; Adding Washer Fluid - GMC 2008 Envoy Denali Owner's Manual

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.

Adding Washer Fluid

Open the cap with the
washer symbol on it.
Add washer fluid until the
tank is full. See Engine
Compartment Overview
on page 5-12 for reservoir
location.
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 the washer fluid tank only three-quarters full
when it is very cold. This allows for fluid
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 the vehicle's
windshield washer system and paint.
