Downloaded from www.Manualslib.com manuals search engine /f No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam, try this for a minute
or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3.
If you’re in a traffic jam, shift to “N” (Neutral).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there’s still no sign
of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now see
if the warning stops.
But then,
if you still have the warning, TURN OFF THE ENGINE AND
GET EVERYONE
OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.
When you decide it’s safe to lift the hood,
here’s what you’ll see:
A. Coolant recovery tank
B. Radiator pressure
C. Engine fan
cap
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until it cools down.

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 to the left until it first stops. (Don’t press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means there is still some
pressure left.
2. Then keep
turning the
pressure cap, but now push down
as you turn it.
Remove the pressure cap.

with the proper
mix, up to the
base
of the filler
neck.
4. Then fill the
coolant recovery
tank to the
ADD
mark.
5. ht the cap back
on the coolant
recovery tank,
but leave the
radiator pressure cap
off.

Radiator Pressure Cap
I 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.
When you replace
your radiator pressure cap, a
GM cap is
recommended. See
“Service Replacement
Part and Filter
Recommendations” in
the Index.

Downloaded from www.Manualslib.com manuals search engine 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.
Power Steering Fluid
NOTICE:
Always turn the engine off before checking or adding power
steering fluid. The power steering cap is close
to the fan and
other moving parts.

To Add
I Open the cap labeled
“WASHER
FLUID
ONLY.” Add washer
fluid until the bottle
is
full.
NOTICE:
When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
0 Don’t mix water with ready-to-use washer fluid. Water can
cause the solution
to freeze and damage your washer fluid
tank and other parts
of the washer system, AIso, water
doesn’t clean as well as washer fluid.
Fill your washer fluid tank only 3/4 full when it’s very cold.
This allows for expansion, which could damage the tank
if it is
completely full.
can damage your washer system and paint.
0 Don’t use radiator antifreeze in your windshield washer. It
Fluid Leak Check
After the vehicle has been parked for a while, inspect the su\
rface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system after it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.

Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system
in your vehicle needs refrigerant, be sure the proper refrigerant is
used. If you’re not sure, ask your
GM dealer. For additional information, see
your “Warranty and Owner Assistance Information” booklet.
Air Conditioning Refrigerant Capacity
TYPE SYSTEM QUANTITY*
R-l34a c-60 30 oz. (35 kg)
*All
q1 Les are approximate. ..
NOTICE:
R-134a refrigerant is not compatible with R-12 refrigerant in
an air conditioning system. R-12 in an R-134a system will caus\
e
compressor failure, refrigerant oil sludge,
or poor air
conditioning system performance.

Downloaded from www.Manualslib.com manuals search engine Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed
in this section. Make sure
whoever services your vehicle uses these. All parts should be \
replaced and
all necessary repairs done before you or anyone else drives the vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* - ALWAYS USE
API SERVICE SH OR SG ENERGY CONSERVING I1 OILS
OF THE
PROPER VISCOSITY. The “SH” or
“SG’ designation may be shown
alone or in combination with others, such as “SWCD”, or
“SH, SG,
CD,” or “SGKD”, etc. To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE 5W-30), see “Engine
Oil” in the Index.
2. CHASSIS LUBRICATION - Lubricate the front suspension, ball
joint, steering linkage, and transfer case shift linkage, parking brake\

cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first
.
Ball joints should not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before
lubricating them or they could be damaged.
Also, be sure
to check all the vehicle fluid levels at this time.
3.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “\
GM
Specification 6038-M” (4.3L engine) or “GM Specification 6043-M”
(2.2L engine). See “Engine Coolant” in the Index for the proper coolant
and mixture to use in your vehicle.
Also inspect the hoses and replace them if they are cracked, \
swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck. To ensure proper operation,
pressure test the radiator and cap.
4. AIR CLEANER FILTER REPLACEMENT* - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
5. FRONT WHEEL BEARING REPACK (%WHEEL DRIVE
ONLY) - Clean and repack the front wheel bearings at each brake
relining, or at the specified interval, whichever comes first.
*An Emission Control Service
