If No Steam Is Coming From

Your Engine

If you get an engine overheat warning but see

or hear no steam, the problem may not be

too serious. Sometimes the engine can get a

little too hot when you:

• Climb a long hill on a hot day.

• Stop after high-speed driving.

• Idle for long periods in traffic.

• Tow a trailer. See “Driving on Grades”

under Towing a Trailer on page 306.

If you get the overheat warning with no sign

of steam, try this for a minute or so:

1. In heavy traffic, let the engine idle in

NEUTRAL while stopped. If it is safe to

do so, pull off the road, shift to PARK (P)

or NEUTRAL and let the engine idle.

2. Turn off the air conditioning.

3. Turn on your heater to full hot at the

highest fan speed and open the windows

as necessary.

If you no longer have the overheat warning,

you can drive. Just to be safe, drive slower

for about 10 minutes. If the warning does not

come back on, you can drive normally.

If the warning continues, pull over, stop, and

park your vehicle right away.

If there is still no sign of steam, idle the engine for

three minutes while you are parked. Push down

the accelerator until the engine speed is about

twice as fast as normal idle speed for at least

three minutes while you are parked. If you

still have the warning, turn off the engine and get

everyone out of the vehicle until it cools down.

You may decide not to lift the hood but to

get service help right away.
