2009 GMC CANYON check engine

How to Add Fluid
Here is how to add uid. Refer to the Maintenance
Schedule to determine what kind of uid to use. See
Recommended Fluids and Lubricants on page 6-11.
1. Remove the ller plug.
2. Add uid at the ller plug hole. Add only enough
uid to bring the uid level up to the bottom of the
ller plug hole.
3. Install the ller plug. Be sure the plug is fully
seated.
Hydraulic Clutch
The hydraulic clutch linkage in the vehicle is
self-adjusting. The clutch master cylinder reservoir is
lled with hydraulic clutch uid.The hydraulic clutch uid
reservoir cap has this
symbol on it. SeeEngine
Compartment Overview
on page 5-12for reservoir
location.
It is not necessary to regularly check clutch uid unless
a leak in the system is suspected. Adding uid will
not correct a leak.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.

When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often to check the uid level in the clutch master cylinder
reservoir and for the proper uid. SeeRecommended
Fluids and Lubricants on page 6-11.
How to Check and Add Fluid
The proper uid should be added if the level does not
reach the bottom of the diaphragm when it is in place in
the reservoir. See the instructions on the reservoir cap.
Cooling System
The cooling system allows the engine to maintain the
correct working temperature.
A. Coolant Recovery Tank
B. Engine Cooling Fan
C. Radiator Pressure Cap

Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a problem
with engine overheating, seeEngine Overheating on
page 5-32.
What to Use
{CAUTION:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch re and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
Gives freezing protection down to−34°F (−37°C),
outside temperature.
Gives boiling protection up to 265°F (129°C),
engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 6-11for more information.
5-28

Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The coolant recovery tank
cap has this symbol on it.
It is located toward the rear of the engine compartment
on the passenger side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location.
Check to see if coolant is visible in the coolant recovery
tank. If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down. If
coolant is visible but the coolant level is not at or above
the FULL COLD mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant at the coolant
recovery tank, but be sure the cooling system is cool
before this is done.The vehicle must be on a level surface. When the engine
is cold, the coolant level should be at FULL COLD, or a
little higher. When the engine is warm, the level could be
above the FULL COLD level.
When the engine is cold, the coolant level should be at
least up to the FULL COLD mark. If it is not, there could
be a leak in the cooling system.
How to Add Coolant to the
Recovery Tank
{CAUTION:
You can be burned if you spill coolant on hot engine
parts. Coolant contains ethylene glycol and it will
burn if the engine parts are hot enough. Do not spill
coolant on a hot engine.
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure could
cause the engine to overheat and be severely
damaged.
When the coolant in the coolant recovery tank is at the
FULL COLD mark, start the vehicle.
If coolant is needed, add the proper DEX-COOL
®
coolant mixture at the coolant recovery tank.
5-29

Engine Overheating
The vehicle has a coolant temperature gage displayed
on the instrument panel to warn if the engine is
overheating. SeeEngine Coolant Temperature
Gage on page 3-29. If the engine is too hot, the air
conditioning might stop working. This is normal
and helps cool the engine.
You may decide not to lift the hood when the warning
appears, but instead get service help right away.
SeeRoadside Assistance Program on page 7-7.
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.
The engine cooling fan speed should increase when
idle speed is doubled by pushing the accelerator pedal
down. If it does not, the vehicle needs service.
Turn off the engine.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.
Notice:If the engine catches re because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.
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. Just 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 your engine is overheated,
the liquids in it can catch re. You or others could
be badly burned. Stop your engine if it overheats,
and get out of the vehicle until the engine is cool.

Power Steering Fluid
The power steering uid
reservoir is located near
the front of the engine
compartment, behind the
radiator. SeeEngine
Compartment Overview on
page 5-12for 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
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Then remove the cap again and look at the uid
level on the dipstick.
The level should be between the ADD and FULL marks.
If necessary, add only enough uid to bring the level
up to the proper range.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 6-11.
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 inRecommended Fluids and Lubricants
on page 6-11.
5-34

Brakes
Brake Fluid
The brake master cylinder
reservoir is lled with
DOT-3 brake uid. See
Engine Compartment
Overview on page 5-12for
the location of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down:
The brake uid level goes down because of normal
brake lining wear. When new linings are installed,
the uid level goes back up.
A uid leak in the brake hydraulic system can also
cause a low uid level. Have the brake hydraulic
system xed, since a leak means that sooner
or later the brakes will not work well.Do not top off the brake uid. Adding uid does not
correct a leak. If uid is added when the linings
are worn, there will be too much uid when new brake
linings are installed. Add or remove brake uid, as
necessary, only when work is done on the brake
hydraulic system.
{CAUTION:
If too much brake uid is added, it can spill on
the engine and burn, if the engine is hot enough.
You or others could be burned, and the vehicle
could be damaged. Add brake uid only when
work is done on the brake hydraulic system.
See “Checking Brake Fluid” in this section.
Refer to the Maintenance Schedule to determine when
to check the brake uid. SeeScheduled Maintenance
on page 6-4.
5-36

Checking Brake Fluid
Check brake uid by looking at the brake uid reservoir.
SeeEngine Compartment Overview on page 5-12.
The uid level should be
above the PP mark. If it
is not, have the brake
hydraulic system checked
to see if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is above the PP mark but not over
the MAX mark.
What to Add
Use only new DOT-3 brake uid from a sealed container.
SeeRecommended Fluids and Lubricants on page 6-11.
Always clean the brake uid reservoir cap and the area
around the cap before removing it. This helps keep
dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake uid.
Notice:
Using the wrong uid can badly damage brake
hydraulic system parts. For example, just a few
drops of mineral-based oil, such as engine oil,
in the brake hydraulic system can damage brake
hydraulic system parts so badly that they will
have to be replaced. Do not let someone put in
the wrong kind of uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 5-103.
