How to Add Coolant to the Radiator
{ WARNING:
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.
{ WARNING:
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.
1. Remove the radiator pressure cap when the cooling
system, including the upper radiator hose, is no
longer hot. Turn the pressure cap slowly
counterclockwise about one full turn.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Keep turning the cap to remove it.
3. Fill the radiator with the proper DEX-COOL
®
coolant mixture, up to the base of the filler
neck. See Engine Coolant on page 6-28 for more
information about the proper coolant mixture.
