How to Add Coolant to the Coolant
Surge Tank
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
If you have not found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level is not between the Minimum and
Maximum marks, add a 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant at the coolant surge tank,
but be sure the cooling system, including the coolant
surge tank pressure cap, is cool before you do it.
SeeEngine Coolant on page 5-22for more information.
If no coolant is visible in the surge tank, add coolant
as follows:
{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 coolant
surge tank pressure cap — even a little — they
can come out at high speed.
CAUTION: (Continued)
CAUTION: (Continued)
Never turn the cap when the cooling system,
including the coolant surge tank pressure cap,
is hot. Wait for the cooling system and coolant
surge tank pressure cap to cool if you ever
have to turn the pressure cap.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and a proper coolant.
5-28

Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{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.
1. You can remove the coolant surge tank pressure
cap when the cooling system, including the
coolant surge tank pressure cap and upper
radiator hose, is no longer hot. Turn the pressure
cap slowly counterclockwise about two or
two and one-half turns.
If you hear a hiss, wait for that to stop. This will
allow any pressure still left to be vented out
the discharge hose.2. Then keep turning the pressure cap slowly, and
remove it.
5-29

3. Fill the coolant surge tank with the proper mixture
to the Maximum mark on the coolant surge tank.
Wait about five minutes, then check to see if
the level is below the mark. If the level is below the
Maximum mark, add additional coolant to bring
the level up to the mark. Repeat this procedure until
the level remains constant at the Maximum mark
for at least five minutes.4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the Maximum mark, add more of the proper mixture
to the coolant surge tank until the level reaches
the mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer/retailer, if necessary.
Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward the
front of the engine compartment on the driver’s side
of the vehicle. SeeEngine Compartment Overview on
page 5-12for reservoir location.
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
5-30

Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have
the right wheel, wheel bolts, wheel nuts, and TPMS
sensors for your vehicle.
{CAUTION:
Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
SeeChanging a Flat Tire on page 5-70for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has been
used or how far it has been driven. It could
fail suddenly and cause a crash. If you have
to replace a wheel, use a new GM original
equipment wheel.

Section 6 Maintenance Schedule
6-1

Selecting the Right Schedule
First you will need to decide which of the two schedules
is right for your vehicle. Here is how to decide which
schedule to follow:
Short Trip/City Denition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
•Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
•Most trips include extensive idling, such as frequent
driving in stop-and-go traffic.
•If the vehicle is used for delivery service, police,
taxi, or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km):Engine Oil and Filter
Change (or 3 months, whichever occurs first).
Every 6,000 Miles (10 000 km):Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Passenger Compartment Air Filter
Replacement. Drive Belt(s) Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Spark Plug Replacement. EVAP
System Service. PCV System Service.
Every 37,500 Miles (60 000 km):Automatic
Transmission Fluid Change (severe service only).
Every 42,000 Miles (70 000 km):Engine Oil Pan Drain
Plug Washer Replacement.
Every 60,000 Miles (100 000 km):Spark Plug Wire
Replacement. Timing Belt Replacement. EVAP System
Solenoid Valve Replacement.
Every 90,000 Miles (150 000 km):Fuel Filter
Replacement.
Every 150,000 Miles (240 000 km):Cooling System
Service.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
6-5

Long Trip/Highway Denition
Follow this scheduled maintenanceonlyif none of
the conditions from the Short Trip/City Scheduled
Maintenance are true. Do not use this schedule if the
vehicle is driven in a dusty area or used off paved roads.
Use the Short Trip/City schedule for these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions will cause engine oil to break
down slower.
Long Trip/Highway Intervals
Every 7,500 Miles (12 500 km):Engine Oil and
Filter Change (or every 12 months, whichever occurs
first). Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Passenger Compartment Air Filter
Replacement. Drive Belt(s) Inspection.
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Spark Plug Replacement. EVAP
System Service. PCV System Service.
Every 37,500 Miles (60 000 km):Automatic
Transmission Fluid Change (severe service only).Every 60,000 Miles (100 000 km):Spark Plug Wire
Replacement. Timing Belt Replacement. EVAP System
Solenoid Valve Replacement.
Every 90,000 Miles (150 000 km):Fuel Filter
Replacement. Engine Oil Pan Drain Plug Washer
Replacement.
Every 150,000 Miles (240 000 km):Cooling System
Service.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.Short Trip/City Scheduled
Maintenance
The services shown in this schedule up to
100,000 miles (166 000 km) should be repeated after
100,000 miles (166 000 km) at the same intervals
for the life of this vehicle. The services shown at
150,000 miles (240 000 km) should be repeated at
the same interval after 150,000 miles (240 000 km)
for the life of this vehicle.
