The coolant level should be at or
above the FULL COLD mark on the
coolant surge tank. If it is not, there
may be a leak at the pressure cap
or in the radiator hoses, heater
hoses, radiator, water pump,
or somewhere else in the cooling
system.
How to Add Coolant to the
Coolant Surge Tank
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.
I n f o r ma t i o n P r o v i d e d b y :
WARNING
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.
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant surge tank.
