How to Add Coolant to the Radiator
Notice: Your engine has a specific radiator fill
procedure. Failure to follow this procedure
could cause your engine to overheat and
be severely damaged.
Turn the pressure cap slowly counterclockwise.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left, close
the cap and wait for the system to cool down.
2. Keep turning the pressure cap. Remove 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.
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. Do not spill
coolant on a hot engine.
3. Fill the radiator with the proper DEX-COOL
coolant mixture, up to the base of the filler
neck. See Engine Coolant on page 432
for more information about the proper coolant
mixture.
4. Rinse or wipe any spilled coolant from the
engine and the compartment.
5. Start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fans.
6. By this time, the coolant level inside the
radiator filler neck may be lower. If the level 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.
