and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
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.
Caution
Warning
Vehicle Care
If no coolant is visible in the surge
tank, add coolant:
1. Remove the coolant surge tank
pressure cap when the cooling
system, including the coolant
surge tank pressure cap and
upper radiator hose, is no
longer hot.
Turn the pressure cap slowly
anticlockwise about one full turn.
If a hiss is heard, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure cap
slowly and remove it.
3. Fill the coolant surge tank with
the proper mixture to the FULL
COLD mark.
