Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. 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 coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done. Then check the
recovery tank and add coolant if
needed.
1. Detach the fasteners and lift off
the panel that covers the
radiator cap.
2. 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 a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left in the
system.
3. Keep turning the pressure cap
slowly and remove it.
4. Fill the radiator to the base of
the filler neck with the proper
DEX-COOL coolant mixture.
