engine coolant GMC ACADIA 2009 Owner's Guide

What to Use
To determine what kind of uid to
use, seeRecommended Fluids and
Lubricants on page 6-12. Always
use the proper uid.
Notice:Use of the incorrect uid
may damage the vehicle and the
damages may not be covered by
the vehicle’s warranty. Always
use the correct uid listed in
Recommended Fluids and
Lubricants on page 6-12.
Windshield Washer Fluid
What to Use
When adding windshield washer
uid, be sure to read the
manufacturer’s instructions before
use. If the vehicle will be operating
in an area where the temperature
may fall below freezing, use a
uid that has sufficient protection
against freezing.
Adding Washer Fluid
When the windshield washer uid
reservoir is low, a WASHER FLUID
LOW ADD FLUID message will be
displayed on the Driver Information
Center (DIC). SeeDIC Warnings and
Messages on page 3-56for more
information.
Open the cap with the washer
symbol on it. Add washer uid
until the tank is full. SeeEngine
Compartment Overview on
page 5-10for reservoir location.Notice:When using concentrated
washer uid, follow the
manufacturer’s instructions
for adding water.
Do not mix water with
ready-to-use washer uid.
Water can cause the solution
to freeze and damage your
washer uid tank and other
parts of the washer system.
Also, water does not clean as
well as washer uid.
Fill the washer uid tank only
three-quarters full when it is
very cold. This allows for uid
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.

(e)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or damaged
safety belt system parts. If you see
anything that might keep a safety belt
system from doing its job, have it
repaired. Have any torn or frayed
safety belts replaced. Also see
Checking the Restraint Systems on
page 1-61.
(f)Lubricate all key lock cylinders,
hood latch assemblies, secondary
latches, pivots, spring anchor and
release pawl, hood and door hinges,
rear folding seats, and liftgate
hinges. More frequent lubrication
may be required when exposed to a
corrosive environment. Applying
silicone grease on weatherstrips with
a clean cloth will make them last
longer, seal better, and not stick or
squeak.
(g)A fluid loss in any vehicle
system could indicate a problem.
Have the system inspected
and repaired and the fluid level
checked. Add fluid if needed.(h)Change automatic transmission
fluid if the vehicle is mainly
driven under one or more of these
conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-17 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.
(j)Check system for interference or
binding and for damaged or missing
parts. Replace parts as needed.
Replace any components that havehigh effort or excessive wear. Do not
lubricate accelerator or cruise control
cables.
(k)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
(l)If driving regularly under dusty
conditions, inspect the filter at each
engine oil change.
(m)Change transfer case fluid if the
vehicle is mainly driven under
one or more of these conditions:
In heavy city traffic where
the outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
