When you decide it’s safe to lift the hood, here’s what you’ll see:
Coolant recovery tank

7 Electric engine fans
’ A CAUTION: I
An 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.

you may have
a leak in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine parts, can be very
hot. Don’t touch them. If you do, you can be burned.
Dodbrun the engine if there is a leak. If you run the engine, it
could lose all coolant. That could cause an engine fire, and you
could be burned. Get any leak Pied before you drive the vehicle.

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.
I
When the coolant in the coolant recovery tank is at or above near “FULL
COLD,” 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.

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 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.

the pressure cap,

on the coolant
recovery tank, but
leave the radiator
pressure cap
off.
6. Start the engine
and let it run
until
you can feel the
upper radiator
hose getting hot.
Watch out for the
engine fans.
7. By this time the coolant level inside the radiator 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.
