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 DEX-COOL coolant
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 fans.

By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
DEX-COOL coolant mixture to

the coolant surge tank until the
level reaches the indicated
level mark.

5. Replace the pressure cap

tightly.

Check the level in the coolant surge
tank when the cooling system has
cooled down. If the coolant is
not at the proper level, repeat
Steps 1

3 and reinstall the pressure

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

Engine Overheating

The vehicle has an engine coolant
temperature gauge and may also
have an engine coolant temperature
warning light on the instrument
cluster to warn of engine
overheating. See
