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.

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 and you have not stopped, 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.

Overheated Engine Protection
Operating Mode
(4.6L V8 Engine Only)

If an overheated engine condition exists and the
message ENGINE OVERHEATED STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and
engine performance. This operating mode allows your
vehicle to be driven to a safe place in an emergency.
Driving extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.

Notice:

After driving in the overheated engine

protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil and
reset the oil life system. See
