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) still using a cloth
the cap, and remove it.
1. Make sure the engine is not running
and it has cooled.
2. Remove the cooling system cap.
