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:
Climb a long hill on a hot day.
0 Stop after high speed driving.
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
3. If you’re in a traffic jam, shift to “N” (Neutral).
window as necessary.
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.

Downloaded from www.Manualslib.com manuals search engine 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. Engine fan
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until it cools down.
The
coolant level should be at or above FULL. 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.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed
is doubled by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn
off the engine.

If you haven’t found a problem yet, but the coolant level \
isn’t at or above
the
FULL mark, add a 50/50 mixture of clean water (preferably distilled)
and
a proper antifreeze at the coolant recovery tank. (See “Engine Coolant”
in the Index for more information about the proper coolant mix.)
..
..
I NOTICE:
In cold weather, water can freeze and crack the engine, radiator,
heater core and other parts. Use the recommended coolant.
When the coolant in the coolant recovery tank is at or above the FULL,
mark, start your vehicle.
If the overheat warning continues, there’s one more thing
you can try. You
can add
the proper coolant mix directly to the radiator, but be sure the
cooling system
is cool before you do it.

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.
