The engine coolant heater, if available, can help in cold weather conditions at or below 0°F (-18°C) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting your vehicle.

1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.

On vehicles with the 3.8L V6 engine, the coolant heater cord is located on the passenger's side of the vehicle, above the headlamp assembly. On vehicles with the 4.6L V8 engine, the cord is located on the driver's 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. If you do not, it could be damaged.

How long should you keep the coolant heater plugged in? The answer depends on the outside temperature, the kind of oil you have, and some other things. Instead of trying to list everything here, we ask that you contact your dealer/retailer in the area where you will be parking your vehicle. The dealer/retailer can give you the best advice for that particular area.
