Engine Coolant Temperature Warning Light
This light tells you that your engine
coolant has overheated or your radiator
cooling fan is not working. If you have
been operating your vehicle under normal driving conditions, you should
pull
off the road, stop your vehicle and
turn the engine
off as soon as possible.
HOT COOLANT CAN BURN YOU
BADLY!
In
Problems on the Road, this manual
shows what to
do. See the Index under
Engine Overheating.
Engine Coolant Temperature
Gage
(OPTION)
If you have the gage cluster, you have a
gage that shows the engine coolant
temperature. If the gage pointer moves
into the red area, your engine is too hot!
That reading means the same thing as
the warning light. It means that your
engine coolant has overheated. If you
have been operating your vehicle under
normal driving conditions, you should
pull
off the road, stop your vehicle and
turn off the engine as soon as possible.

Low Coolant Warning Light
(v6 ENGINES)
If this light comes on, your system is
low on coolant and the engine may
overheat. See the
Index under Engine
Coolant and have your vehicle serviced
as soon as you can.

Engine:
If you get the overheat warning but see
or hear no stem, the problem may not
be
too serious. Sometimes the engine
can get
a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no
sign of steam, try this for a minute or

Engine Overheating
You will find a coolant temperature
gage or the warning light about a hot
engine on your Chewolet’s instrument
panel. You also have a low coolant
warning light on your instrument panel.
See the
Index under Coolant
Temperature Gage for the gage cluster. Steam from
an overheated
engine can burn you badly,
/I‘ even if you just open the hood. Stay
away from the engine if you see or
hear steam coming from it. Just
turn it
off and get everyone away
from the vehicle until it cools down.
Wait until there is no sign of steam
or coolant before opening the hood.
If you keep driving when your
engine
is overheated, the liquids in
it can catch fire. You or others
could be badly burned. Stop your
engine
if it overheats, and get out of
the vehicle until the engine
is cool.
2. Tm on your heater to full hot at the
I I highest fan speed and open the
window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine
I runs slower). IL

The proper fluid should be added if the
level does not reach the bottom of the
diaphragm when it’s
in place in the
reservoir. See the instructions on the
reservoir cap.
Engine Coolant
The following explains your cooling
system and how to add coolant when it
is low. If you have a problem with
engine overheating or
if you need to add
coolant to your radiator, see the
Index
under Engine Overheating.

Adding only plain water to
your cooling system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant
mix. With plain water or the wrong
mix, your engine could get too hot
but you wouldn’t get the overheat
warning. Your engine could catch fire and you or others could be
burned. Use a
50/50 mix of clean
water and a proper antifreeze.

Radiator Pressure Cap
214
Your radiator cap is a 15 psi
(105 Wa) pressure-type cap and
must be tightly installed to prevent
coolant loss and possible engine
damage
from overheating. Be su
the arrows on the cap line up wi
the overflow tube on the radiato
filler neck.
When you replace your radiator
pressure cap, an
AC@ cap is
recommended.
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
How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level
on
the dipstick.
When the engine compartment is hot,
When the engine compartment is cool,
the
level should be at the
H mark.
the level should be at the
C mark.

6 Camshaft Timing Belt Inspection (3.4L Code X
engine only)*-Inspect for cracks, wear or oiliness.
Check tensioner for proper operation. See the
service manual.
(To purchase a service manual,
see the
Index under Service Publications.)
Replace parts as needed.
Cooling System Service*-Drain, flush and refill
the system with new or approved recycled coolant
conforming to
GM Specification 1825M. Keep
coolant at the proper mixture as specified. See the
Index under Coolant. This provides proper freeze
protection, corrosion inhibitor level and engine
operating temperature.

Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash the pressure cap
and neck.
To help ensure proper operation, we recommend a
pressure test of both the cooling system and the
pressure cap.
Transaxle Service-For manual transaxles, fluid
doesn’t require changing.
For automatic transaxles, change both the fluid
and filter every 15,000 miles (25
000 km) if the
vehicle is mainly driven under one or more
of
these conditions:

SERVICE
In heavy city traffic where the outside
temperature regularly reaches
90°F (32°C) or
higher.
In hilly or mountainous terrain.
When doing frequent trailer towing. (With some
models you shouldn’t ever tow a trailer. See the
Index under Towing a Trailer.)
Uses such as found in taxi, police car or delivery
service.
If you do not use your vehicle under any of these
conditions, change both the fluid and filter every
100,000 miles
(160 000 km).
Spark Plug Replacement*-Replace spark plugs
with the proper type. See the
Index under
Replacement Parts.
Spark Plug Wire Inspection*+Inspect for
burns, cracks
or other damage. Check the boot fit
at the coils and at the spark plugs. Replace wires
as needed.
