Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn off all
the accessories, and turn on the
hazard warning lights.
2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. If you do not see steam or spray,
leave the engine running, and
check the high temperature
indicator. If the high heat is due to
overloading, the engine should
start to cool down almost
immediately. If it does, wait until
the high temperature indicator
goes off, then continue driving.
4. If the high temperature indicator
stays on, turn off the engine.

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 412 ).
6. If you don't find an obvious leak,
check the coolant level in the
radiator reserve tank (see page
289 ). 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.
