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 287
for 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. 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.
294

{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.
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.
295

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, 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 276for 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.
297

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, or wheel nuts, replace them only with
new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel
bolts, and wheel nuts 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 336for 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.

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

Every 30,000 Miles (50 000 km):Engine Air
Cleaner Filter Replacement. Spark Plug

Service. Timing Belt Inspection. Brake/Clutch Fluid
Change (or 24 months, whichever occurs first).
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
