If No Steam Is Coming From

Your Engine

The ENGINE COOLANT HOT message, along with a

low coolant condition, can indicate a serious problem.

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 Towing a Trailer on page 4-62.

If you get the ENGINE COOLANT HOT message with

no sign of steam, try this for a minute or so:

1. If you have an air conditioner and it is on, turn it off.

2. Turn on your heater to full hot at the highest fan

speed and open the windows as necessary.

3. 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.

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 and your vehicle is

equipped with an engine-driven cooling fan, 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 there is still no sign of steam and your vehicle is

equipped with an electric cooling fan, 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. Also,

see “Overheated Engine Protection Operating Mode”

later in this section.

You may decide not to lift the hood but to get service

help right away.
