If you have the standard cluster, you have a gage that shows the\
engine
coolant temperature.
If the gage pointer moves to the H (red) side, your
engine is too hot!
It means that your engine coolant has overheated.
If you have been
operating your vehicle under normal driving conditions, you shou\
ld pull
off the
road, stop your vehicle and turn
off the engine as soon as possible.
If you have a digital cluster, a
box around the temperature symbol will also
flash
if your engine is too hot.
HOT COOLANT CAN BURN YOU BADLY!
In “Problems on the Road,” this manual shows what to do. See “Engine
Overheating” in the Index.

Downloaded from www.Manualslib.com manuals search engine Don’t have your vehicle towed with the wheels in contact with the ground if
it has all-wheel drive. If a vehicle with all-wheel drive must be towed with
sling-type
or wheel lift equipment, then either the front or rear wheels must
be supported on a dolly.
If your vehicle has rear-wheel drive, don’t have it towed on t\
he rear wheels
unless you must.
If a vehicle with rear-wheel drive must be towed on the rear
wheels, don’t go more than
35 mph (56 kmlh) or farther than 50 miles
(80 km) or your transmission will be damaged. If these limits must be
exceeded, then the rear wheels have to be supported on a doll\
y.
1 CAUTION
L A vehicle can fall from a car carrier if it isn’t properly secured. This
b can cause a collision, serious personal injury and vehicle dama\
ge.
The vehicle should be tightly secured with chains or steel cab\
les
before it is transported.
Don’t use substitutes (ropes, leather straps, canvas webbing,\
etc.)
that can be
cut by sharp edges underneath the towed vehicle.
Engine Overheating
You will find a coolant temperature gage and the warning light about a hot
engine on your vehicle’s instrument panel.

The following explains your cooling system and how to add cool\
ant when it is low.
If you have a problem with engine overheating, see "Engine
Overheating" in the Index.
The proper coolant for your vehicle will:
Give freezing protection down to -20°F (-29°C) or -40°F (-40°C) for
Canadian vehicles and vehicles with the cold climate option.
Give boiling protection up to 258°F (125°C).
Protect' against rust and corrosion.
Help keep the proper engine temperature.
Let the warning gages work as they should,
What to Use:
Use a mixture of clean water (preferably distilled) and antifreeze that meets
"GM Specification 6038-M," which won't damage aluminum parts.
Also use
GM Engine Coolant Supplement (sealer) with a complete coolant \
change.
If
you use these, you don't need to add anything else.

"wr radiator pressure cap is a 15 psi (1 05 kPa) pressure-type cap and
wst be tightly installed to prevent coolant
loss and possible engine
damage from overheating. Be sure the arrows on the pressure cap

When you replace your radiator pressure cap, ul~ AC@ cap is IGdommendGu.
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.
