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.

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.

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.
