WARNING

Removing the Cooling System Cap:
Removing the cooling system cap
while the engine is running or hot is
dangerous. This might lead to cooling
system and engine damage and could
result in serious injury from escaping
hot coolant or steam. Turn off the
engine and wait until it's cool. Even
then, be very careful when removing
the cap.
Wrap a thick cloth around the cap and
slowly turn it counterclockwise to the
first stop (3.0-liter engine) or about
two and a half rotations (2.3-liter
engine).
Step back while the pressure escapes.
When you're sure all the pressure is
gone, press down on the cap (3.0-liter
engine)

—

2. Only when the engine is cool, remove

the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.

3. Flush out the system with running

water.

4. Drain the system completely. Insert and

tighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water as necessary to provide
freezing and corrosion protection.

5. In extremely cold climates, add the

mixture percentage recommended in
the coolant mixture percentage table.

6. Run the engine at idle with the cooling

system cap off. Slowly add additional
coolant if necessary.

7. At this point, wait until the engine

reaches normal operating temperature;
then depress the accelerator two or
three times. Add more coolant, if
necessary, until the system is full.

8. Install the cooling system cap. Inspect

all connections for leaks. Inspect the
level in the coolant reservoir one more
time.
