To Use the Engine Coolant Heater

1. Turn off the engine.

2. Open the hood and unwrap the electrical cord.

On vehicles with the 3.9L V6 engine, the coolant
heater cord is located on the driver side of the
vehicle, near the strut tower. On vehicles with the
4.6L V8 engine, the cord is located on the driver
side of the vehicle on the right side of the engine air
cleaner. It is between the engine cover and the
engine air cleaner.

{

CAUTION:

Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.

3. Plug the cord into a normal, grounded 110-volt AC

outlet.

4. Before starting the engine, be sure to unplug and

store the cord as it was before to keep it away
from moving engine parts, and prevent damage.

The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.
