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 your vehicle has air conditioning, the auxiliary
electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don't
do anything else until it cools down.

engine parts. Coolant contains ethylene glycol
and it will

a hot engine.

When the coolant in the coolant recovery tank is at
ADD, 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.

cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have to

A
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 counterclockwise 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.

of the filler neck.
4. Then fill the coolant recovery tank to the ADD mark.
5. Put the cap back on the coolant recovery tank, but
leave
the radiator pressure cap off.

upper radiator hose getting hot. Watch out for the
engine fan.
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.
7. By this time the coolant level inside the radiator

this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows on the pressure cap line up like this.

Downloaded from www.Manualslib.com manuals search engine Checking 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.
Adding Coolant
If you need more coolant, add
the proper mix at the
coolant
recovery tank.
A CAUTION:
I--
lbrning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little -- when the engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will
burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

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.
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 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.
