If the Engine Overheats
4. If the temperature gauge stays at
the red mark, turn off the engine.
5. Look for any obvious coolant
leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 602).
6. If you do not find an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the
temperature gauge, or lower,
before checking the radiator.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.

9. Start the engine and set the
climate control to AUTO at ''Hi.''
Add coolant to the radiator up to
the base of the filler neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see Emergency
Towing on page 602).
11. If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.
