236 Vehicle Care
If ambient temperatures are
anticipated below−28 °C (−18 °F),
make sure a proper mixture ratio of
50% DEX-COOL coolant and 50%
clean, drinkable water is used.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the cold fill line, add a
mixture of 40% DEX-COOL coolant
and 60% clean, drinkable water at
the coolant recovery tank, but be
sure the cooling system is cool
before this is done. See Engine
Overheating 0237.
The engine coolant surge tank is
toward the rear of the engine
compartment on the passenger side
of the vehicle. See Engine
Compartment Overview 0218.
When the engine is cold, the coolant
level should be at the cold fill line on
the coolant surge tank.
When the engine is hot, the level
could be higher than the cold fill
line. If the coolant is below the cold
fill line when the engine is hot, there
could be a leak in the cooling
system.
If the coolant is low, add the coolant
or take the vehicle to your dealer for
service.
How to Add Coolant to the
Coolant Surge Tank
{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.
{Warning
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
DEX-COOL coolant mixture directly
to the surge tank, but be sure the
cooling system is cool before this
is done. 1. When the cooling system, including the coolant surge
tank pressure cap and upper
radiator hose, is no longer hot,
remove the pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
If a hiss is heard, wait for that
to stop. A hiss means there is
still some pressure left.
