A CAUTION:
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,

Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can’be burned.
Don’t run the engine

an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.

Downloaded from www.Manualslib.com manuals search 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 the ADD mark, add a SO/SO mixture of clenrz
wter (preferably distilled) and DEX-COOL”
(silicate-free) antifreeze at the coolant recovery tank.
(See ”Engine Coolant”
in the Index for more
information.)
A CAUTION:
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 >‘ou wouldn’t get the overheat
warning. k‘our
engine could catch fire and you or
others
could he hurned. Use a 50/50 mix of clean
water and DKX-CWOL” coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant
mix.

I 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.
When the coolant in the coolant recovery tank is at 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.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
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
turn the pressure cap.

1. You can remove the pressure cap when the cooling
system, including the 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.

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 Ievel is lower. add more of the
proper
DEX-COOL@ coolant mixture 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 the pressure cap line up like this.
