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.
How to Add Coolant to the Cooling
System (V6 Engines)
Notice: Your engine has a specific radiator fill
procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.
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 cap slowly
counterclockwise.
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 and remove it.
{
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 5-26 for more
information about the proper coolant mixture.
