Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 438
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.
439

Checking Coolant
The coolant recovery
tank is located on the
driver’s side of the
vehicle, above
the engine air
cleaner/lter. See
Engine Compartment
Overview on page 438
for more information
on location.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be at
the full cold mark, or a little higher. When your
engine is warm, the level should be above the full
cold mark or a little higher. The full cold mark
is a line with an arrow pointing down at it, located
on the front of the coolant recovery tank.
Adding Coolant
If you need more coolant, add the proper
DEX-COOL®coolant mixture at the coolant
recovery tank, but be careful not to spill it.
{CAUTION:
Turning the radiator pressure cap when
the engine and radiator are hot can allow
steam and scalding liquids to blow out
and burn you badly. With the coolant
recovery tank, you will almost never have
to add coolant at the radiator. Never turn
the radiator pressure cap — even a
little — when the engine and radiator
are hot.
450

{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.
Occasionally check the coolant level in the
radiator. For information on how to add coolant to
the radiator, seeCooling System on page 454.
Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly
installed to prevent coolant loss and possible
engine damage from overheating. Be sure
the cap is properly closed.
SeeEngine Compartment Overview on page 438
for more information on location.
Engine Overheating
You will nd an engine coolant temperature gage
on your vehicle’s instrument panel. SeeEngine
Coolant Temperature Gage on page 241.
Your vehicle may also have an ENGINE
COOLANT HOT message displayed in the Driver
Information Center (DIC). SeeDIC Warnings
and Messages on page 256.

Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Radiator Pressure Cap
B. Electric Engine Cooling Fans
C. Engine Coolant Recovery Tank
D. Recovery tank FULL COLD mark{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.
If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
The coolant level should be at or above the
full cold mark. If it is not, you may have a leak at
the pressure cap or in the radiator hoses,
heater hoses, radiator, water pump, or somewhere
else in the cooling system.
454

If the overheat warning continues, there is one
more thing you can try. You can add the proper
coolant mixture directly to the radiator, but be sure
the cooling system is cool before you do it.
{CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn
you badly. They are under pressure, and if
you turn the radiator pressure cap — even
a little — they can come out at high
speed. Never turn the cap when the
cooling system, including the radiator
pressure cap, is hot. Wait for the cooling
system and radiator pressure cap to cool
if you ever have to turn the pressure cap.
How to Add Coolant to the Radiator
Notice:Your engine has a specic radiator ll
procedure. Failure to follow this procedure
could cause your engine to overheat and
be severely damaged.
1. You can remove the
radiator pressure
cap when the
cooling system,
including the radiator
pressure cap and
upper radiator hose,
is no longer hot.
Turn the pressure cap slowly
counterclockwise. If you hear a hiss, wait for
that to stop. A hiss means there is still
some pressure left, close the cap and wait for
the system to cool down.
457

2. Keep turning the pressure cap. Remove the
pressure cap.
{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.
3. Fill the radiator with the proper DEX-COOL
®
coolant mixture, up to the base of the ller
neck. SeeEngine Coolant on page 448
for more information about the proper coolant
mixture.4. Rinse or wipe any spilled coolant from the
engine and the compartment.
5. Start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fans.
6. By this time, the coolant level inside the
radiator ller neck may be lower. If the level is
lower, add more of the proper DEX-COOL
®
coolant mixture through the ller neck until the
level reaches the base of the ller neck.
7. Then replace the pressure cap. At any time
during this procedure if coolant begins to ow
out of the ller neck, reinstall the pressure
cap. Be sure the pressure cap is closed
properly.

Maintenance Footnotes
#Lubricate the suspension, steering linkage,
transaxle shift linkage, and the underbody contact
points and linkage.
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check
parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts, signs of wear, or lack of lubrication. Inspect
power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chang, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. If your vehicle
has a built-in child restraint, make sure the harness
straps, latch plates, buckle, clip, child head
restraint, and anchorages 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 look for any opened or broken
airbag coverings, and have them repaired
or replaced. The airbag system does not need
regular maintenance.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring
anchor and release pawl, hood and door hinges,
rear folding seats, liftgate hinges, fuel door
hinge, power sliding door cable, and sliding door
track(s). More frequent lubrication may be required
when exposed to a corrosive environment.
