If the Engine Overheats
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 311).
6. If you don't 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 high
temperature indicator goes off
before checking the radiator.
302
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
temperature control dial to
maximum heat. 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 high temperature indicator. If
it begins to blink or comes on
again, the engine needs repair (see
Emergency Towing on page 311).
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.
