If No Steam Is Coming From Your

Engine

An overheat warning, along with a low coolant light, can

indicate a serious problem. See Low Coolant Warning

Light on page 3-30.

If you get an engine overheat warning with no low

coolant light, 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.

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 (N)

while stopped. If it is safe to do so, pull off the road,

shift to PARK (P) or NEUTRAL (N) and let the

engine idle.

2. 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, you can idle the engine

for 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.
