Caution

In cold weather, water can freeze
and crack the engine, radiator,
heater core, and other parts. Use
the recommended coolant and
the proper coolant mixture.

{

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.

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
counterclockwise about
one-quarter of a turn. If you
hear a hiss, wait for that to

stop. This will allow any
pressure still left to be vented
out the discharge hose.

2. Keep turning the pressure cap

slowly and remove it.

3. Fill the coolant surge tank with

the proper mixture to the
indicated level mark.

4. With the coolant surge tank

pressure cap off, start the
engine and let it run until you
can feel the upper radiator
hose getting hot. Watch out for
the engine cooling fan.

By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level reaches the
indicated level mark.

5. Replace the pressure cap

tightly.

6. Verify coolant level after the

engine is shut off and the
coolant is cold. If necessary,
repeat coolant fill procedure
Steps 1

6.

If the coolant still is not at the
proper level when the system
cools down again, see your
dealer.

Caution

If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.

Engine Overheating

The vehicle has several indicators
to warn of the engine overheating.

The instrument cluster has an
engine coolant temperature gauge
and an engine coolant temperature
warning light.
