coolant temperature GMC ACADIA 2009 User Guide

9. If the coolant level inside the
radiator ller neck is low, add
more of the proper DEX-COOL
coolant mixture through the
ller neck until the level is back
up to the base of the ller
neck. Replace the pressure cap.
Be sure to secure it tightly.
Notice:If the pressure cap is
not tightly installed, coolant loss
and possible engine damage
may occur. Be sure the cap is
properly and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gage on the instrument
panel cluster. SeeEngine Coolant
Temperature Gage on page 3-40.The vehicle may also display
an ENGINE OVERHEATED
IDLE ENGINE and ENGINE
OVERHEATED STOP ENGINE
message in the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-56.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
SeeRoadside Assistance Program
on page 7-6.
If you do decide to lift the hood,
make sure the vehicle is parked
on a level surface
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are
not, do not continue to run the
engine and have the vehicle
serviced.Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:If the engine catches re
while driving with no coolant, the
vehicle can be badly damaged.
The costly repairs would not be
covered by the vehicle warranty.
SeeOverheated Engine Protection
Operating Mode on page 5-23for
information on driving to a safe
place in an emergency.
Service and Appearance Care 5-21

If Steam Is Coming From The
Engine Compartment
{CAUTION
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Turn it off
and get everyone away from the
vehicle until it cools down. Wait
until there is no sign of steam or
coolant before you open the hood.
If you keep driving when the
vehicles engine is overheated, the
liquids in it can catch re. You or
others could be badly burned.
Stop the engine if it overheats,
and get out of the vehicle until the
engine is cool.
SeeOverheated Engine
Protection Operating Mode on
page 5-23for information on
driving to a safe place in an
emergency.
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be too
serious. Sometimes the engine can
get a little too hot when the vehicle:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to
N (Neutral), otherwise, shift
to the highest gear while
driving—D(Drive) or L (Low).If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull
over, stop, and park the vehicle
right away.
If there is no sign of steam, idle
the engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating Mode”
next in this section.
5-22 Service and Appearance Care

Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe place
in an emergency situation. If an
overheated engine condition exists,
an overheat protection mode which
alternates ring groups of cylinders
helps prevent engine damage. In this
mode, there is a signicant loss in
power and engine performance.
The temperature gage indicates an
overheat condition exists. Driving
extended distances and/or towing a
trailer in the overheat protection
mode should be avoided.
Notice:After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to
cool before attempting any repair.
The engine oil will be severely
degraded. Repair the cause
of coolant loss, change the oil
and reset the oil life system.
SeeEngine Oil on page 5-11.
Power Steering Fluid
The power steering uid reservoir
is located toward the front of the
engine compartment on the
passenger side of the vehicle.
SeeEngine Compartment Overview
on page 5-10for reservoir location.
When to Check Power
Steering Fluid
It is not necessary to regularly
check power steering uid unless
you suspect there is a leak in
the system or you hear an unusual
noise. A uid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
To check the power steering uid:
1. Turn the key off and let the
engine compartment cool down.
2. Remove engine oil ll cap.
3. Slide engine cover rearward and
lift to remove.
4. Wipe the cap and the top of the
reservoir clean.
5. Unscrew the cap and wipe the
dipstick with a clean rag.
6. Replace the cap and completely
tighten it.
7. Remove the cap again and look
at the uid level on the dipstick.
The uid level should be somewhere
between MAX and MIN line on the
dipstick in room temperature. If the
uid is on or below MIN line, you
should add uid close to MAX Line.
Service and Appearance Care 5-23

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.
5-24 Service and Appearance Care

(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.
