0 When using concentrated washer fluid, follow the
manufacturer’s instructions for adding water.
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. Also, 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,
Don’t use radiator antifreeze in your windshield washer. It
can damage your washer system and paint.

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.
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 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.
When
you decide it’s
safe to
lift the hood,
here’s what you’ll see:
A. Coolant recovery
B. Radiator pressure
C. Engine fan tank

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 the ADD 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.
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.
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
the
ADD 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.)

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 the ADD
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.

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.

pressure cap, but
now push down
as
you turn it.
Remove the
pressure cap.

on the coolant
recovery tank,

off'.
6. Start the engine
and let it run until
you can feel the
upper radiator
hose getting hot.
Watch out for the
engine fan.
7. By this time the coolant level inside the filler neck may be lower. If the
level
is lower, add more of the proper mix through the filler neck until
the
level reaches the base of the filler neck.
8. Then replace the
pressure cap. At
any time during
this procedure if
coolant begins to
flow out of the
filler neck,
reinstall the
pressure cap. Be
sure the arrows
on pressure cap
line
up like this.

If you use an improper coolant mix, your engine could overheat
and be badly damaged. The repair cost wouldn’t be covered by
your warranty.
Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.
Some conditions, such as air trapped in the cooling system, can affect the
coolant level in the radiator. Check the coolant level when the engine
is cold
and follow the steps under “Adding Coolant” for
the proper way to add
coolant.
If you have to add coolant more than four times a year, have your dealer
check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to add extra
inhibitors or additives which claim to improve the system. These
can be harmful.
Adding Coolant
To Check Coolant
When your engine is cold, the coolant level should be at “ADD,” or a little
higher. When your engine
is warm, the level should be up to “FULL HOT,”
or a little higher.
To Add Coolant
If you need more
coolant, add the
proper mix
at the
coolant recovery tank.
