If Your Engine Overheats  
The high temperature indicator  
should not come on under most  
conditions. It may begin to blink if  
you are driving up a long steep hill  
on a very hot day. If it comes on, you  
should determine the reason.  
3. If you do not see steam or spray,  
leave the engine running and  
watch the high temperature  
indicator. If the high heat is due to  
overloading (climbing a long,  
steep hill on a hot day with the  
A/C running, for example), the  
engine should start to cool down  
almost immediately. If it does, wait  
until the high temperature  
Steam and spray from an  
overheated engine can  
seriously scald you.  
Do not open the bonnet if  
steam is coming out.  
Driving when the high temperature  
indicator keeps coming on can cause  
serious damage to your engine.  
1. Safely pull to the side of the road.  
Put the transmission in neutral or  
Park, and set the parking brake.  
Turn off the heating and cooling/  
climate control system and all  
other accessories. Turn on the  
hazard warning lights.  
indicator turns off, then continue  
driving.  
Your vehicle can overheat for several  
reasons, such as lack of coolant or a  
mechanical problem. If the high  
temperature indicator turns on with  
the engine running or you see steam  
or spray coming from under the  
bonnet, you should take immediate  
action.  
4. If the high temperature indicator  
still turns on, turn off the engine.  
5. Wait until you see no more signs  
of steam or spray, then open the  
bonnet.  
2. If you see steam and/or spray  
coming from under the bonnet,  
turn off the engine.

6. 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 381 ).  
10.Start the engine and set the  
temperature control dial to  
maximum. 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.  
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.  
Remember to have the cooling  
system drained and refilled with  
the proper mixture as soon as you  
can.  
7. If you don’t find an obvious leak,  
check the coolant level in the  
radiator reserve tank (see page  
236 ). If the level is below the  
MIN mark, add coolant to halfway  
between the MIN and MAX marks.  
9. Using gloves or a large heavy  
cloth, turn the radiator cap anti-  
clockwise, without pushing down,  
to the first stop. This releases any  
remaining pressure in the cooling  
system. After the pressure  
11.Put the radiator cap back on  
tightly. Run the engine and watch  
the high temperature indicator. If  
it turns on again, the engine needs  
repair (see Emergency Towing  
on page 381 ).  
8. If there was no coolant in the  
reserve tank, you may also have to  
add coolant to the radiator. Let the  
engine cool down until the high  
temperature indicator turns off  
before checking the radiator.  
releases, push down on the cap  
and turn it until it comes off.  
12.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.
