If you get the overheat warning with no
sign
of steam, try this for a minute or
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the
SO:
highest fan speed and open the
window as necessary.
3. Try to keep your engine under load
(in a drive gear where the engine
runs slower).
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, If
there’s still
no sign of steam, you can
idle
the engine for two or three minutes
while you’re parked, to
see if the
warning
stops. But then, if you still
have the warning,

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else until it cools down.
ProCarManuals.com

The coolant level should be at or above
the
COLD mark. If it isn’t, you may
have a leak in the radiator hoses, heater
hoses, radiator, water pump or
somewhere else in the cooling system.
~ CAUTION
A
Heater and radiator hoses,
and other
engine parts, can
be very hot. Don’t touch them. If
you do, you can be burned.
Don’$ run the engine if there is a
leak. If you run the engine, it could
lose all coolant. That could cause
an engine fire, and you could be
burned. Get any leak fixed before
I vou drive the vehicle.
If there seems to be no leak, check to
see if the electric engine fan is running.
If the engine is overheating, the fan
should be running. If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank:
If you haven’t found a problem yet, but
the coolant level isn’t at or above
COLD, add a 50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze at the coolant recovery tank.
(See the
Index under Engine Coolant
for more information about the proper
coolant mix.)
A
Adding only plain water to
your cooling system
can be
dangerous. Plain water,
or some I
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.

Gasolines for Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits
from forming in your engine and fuel
system. That helps keep your engine in
tune and your emission control system
working properly. It’s good for your
vehicle, and you’ll be doing your part
for cleaner air.
Many gasolines are now blended with
materials called oxygenates. General
Motors recommends that you use
gasolines with these blending materials,
such
as MTBE and ethanol. By doing
so, you can help clean the air, especially
in those parts of the country that have
high carbon monoxide levels.
214
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed
to reduce vehicle emissions. General
Motors recommends that
you use
reformulated gasoline. By doing
so, you
can help clean the air, especially in
those parts
of the country that have
high ozone levels.
You should ask your service station
operators
if their gasolines contain
detergents and oxygenates, and
if they
have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another
country outside the
U.S. or Canada,
unleaded fuel may be hard to find.
Do
not use leaded gasoline. If you use even
one tankful, your emission controls
won’t work well or at all. With
continuous use, spark plugs can get
fouled, the exhaust system can corrode,
and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means
costly repairs that wouldn’t be covered
by your warranty.

Eagine Oil
It’s a good idea to check your engine oil
every time you get fuel.
In order to get
an accurate reading, the oil must be
warm and the vehicle must be on level
ground. Turn
off the engine and give
the oil a few minutes to drain back into
the oil pan.
If you don’t, the oil dipstick
might not show the actual level.
To Check Engine Oil:
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back
in all the way. Remove it again, keeping
the tip lower.

When to Add Oil:
If the oil is at or below the ADD line,
then you’ll need to add some
oil. But
you must use the right kind. This
section explains what kind
of oil to use.
