Adding Coolant - Diesel Engine
x " The coolant surge tank is located on
the
passenger side at the
rear corner of the
engine compartment.
To Check Coolant
A CAUTION:
lbrning the surge tank pressure cap when the engine and
radiator are hot can allow steam and scalding liquids to blow \
out
and burn you badly. Never turn the surge tank pressure
cap -
even a little - when the engine and radiator are hot.
When your engine is cold, the coolant level should be at the COLD mark. or
a little higher.
If this light comes on, it means you're low on engine coolant.

To Add Coolant
If you need more coolant, add the proper mix crt the surge tunk, but only
when the engine
is cool. If the surge tank is empty, see “Engine
Overheating”
in the Index for the proper fill procedure.
A 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. Don’t spill coolant on
a hot engine.
When replacing the pressure
cap, make sure it is tight.

NOTICE:
Your radiator cap is a 15 psi (105 kPa) pressure-type cap and
must be tightly installed to prevent coolant
loss and possible
engine damage from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator filler neck.

Surge Tank Pressure Cap - Diesel Engine
The surge tank
pressure cap must
be
tightly installed with
the arrows on the cap
lined up with the top
tube
of the coolant
surge tank.
NOTICE:
Your surge tank pressure cap is a unique 15 psi (105 kPa)
pressure-type cap for use with surge tank cooling systems only.
It must be tightly installed to prevent coolant
loss and possible
engine damage from overheating. Be sure the arrows on the cap
line up with the top tube of the coolant surge tank.
Thermostat
Engine coolant temperature is controlled by a thermostat in the engine
coolant system. The thermostat stops the flow
of coolant through the
radiator
until the coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

Inflation - lire Pressure
The CertificationD’ire label which is on the rear edge of the driver’s door, or
on the incomplete vehicle document in the cab, shows the correct inflation
pressures for your tires, when they’re cold. “Cold” means your vehicle has
been sitting for at least three hours or driven no more than a mile.
You can operate some vehicles at reduced inflation pressures
only when
you’ll be carrying reduced loads. On those vehicles, the minimum cold
inflation pressures for a typical reduced load are printed on the “Improved
Ride Tire Pressure” label located on
the driver’s door. Weigh the vehicle to
find the load on each tire and see the label for the minimum cold inflation
pressures for that load.

NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not.
If your tires don’t have enough air
(underinflation) you can get:
Too much flexing
0 Too much heat
Tire overloading
Bad wear
Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the tire pressure of the
spare tire.
How to Check
Use a good quality pocket-type gage to check tire pressure. Simply looking
at the tires will not tell you the pressure, especially if you have radial tires
- which may look properly inflated even if they’re underinflated.
If your tires have valve caps, be sure
to put them back on. They help prevent
leaks by keeping
out dirt and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km)
for any signs
of unusual wear. If unusual wear is present, rotate your tires as
soon as possible and check wheel alignment. Also check for damaged tires
or wheels. See “When it’s Time for New Tires’’ and “Wheel Replacement”
later
in this section for more information.

The purpose of regular rotation is to achieve more uniform wear for all tires
on the vehicle. The first rotation
is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled rotation intervals.
FRT FRT
When rotating your
tires, always use the
correct rotation
pattern shown here.
When rotating your
tires,
always use one
of the correct rotation
patterns shown here.
After the tires have been rotated, adjust the front and rear inflation pressures
as shown
on the CertificatiodTire label. Make certain that all wheel nuts are
properly tightened.
See “Wheel Nut Torque” in the Index.

Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean off better with
iust water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with a clean, dull knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the outside of the
stain, “feathering” toward the center. Keep changing to
a clean section
of the cloth.
When you clean a stain from fabric, immediately dry the area with a
blow dryer to help prevent a cleaning ring. (See the previous NOTICE.)

Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle
in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (mild
detergent) soaps. Don’t use cleaning agents that are petroleum based, or
that
contain acid or abrasives. All cleaning agents should be flushed promptly
and
not allowed to dry on the surface, or they could stain. Dry the finish
with a soft, clean chamois or a 100% cotton towel to avoid surface scratches
and water spotting.
High pressure car washes may cause water
to enter your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle by hand may be
necessary to remove residue from the paint finish.
You can get GM
approved cleaning products from your dealer. (See “Appearance Care and
Materials”
in the Index.)
Your vehicle has
a “basecoat/clearcoat” paint finish. The clearcoat gives
more depth
and gloss to the colored basecoat. Always use waxes and
polishes that are non-abrasive and made for
a basecoatklearcoat paint
finish.
NOTICE:
Machine compounding or aggressive polishing on a
basecoatklearcoat paint finish may dull the finish or leave swirl
marks.
Foreign materials such as calcium chloride and other salts, ice melting
agents, road oil and tar, tree sap, bird droppings, chemicals from industrial
chimneys, etc. can damage your vehicle’s finish
if they remain on painted
surfaces. Wash the vehicle
as soon as possible. If necessary, use
non-abrasive cleaners that are marked safe for painted surfaces to remove
foreign matter.
Exterior painted surfaces are subject
to aging, weather and chemical fallout
that can take their toll over
a period of years. You can help to keep the paint
finish looking new by keeping your vehicle garaged or covered whenever
possible.
