How to Add Coolant to the Radiator

CAUTION:
{
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan.
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 surge tank
pressure cap — even a little — they can come out
at high speed. Never turn the cap when the
cooling system, including the surge tank pressure
cap, is hot. Wait for the cooling system and surge
tank pressure cap to cool if you ever have to turn
the pressure cap.

If coolant is needed, add the proper mixture directly to
the radiator, but be sure the cooling system is cool
before this is done.
2. Keep turning the pressure cap and remove it.
3. Fill the cooling system with the proper DEX-COOL
coolant mixture, up to the base of the filler neck.
See Engine Coolant on page 5-28 Engine Coolant
for more information about the proper coolant
mixture. Rinse or wipe any spilled coolant from the
engine and the compartment.
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.
If you hear a hiss, wait for
that to stop. A hiss means
that there is still some
pressure left.
