To Use The Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The electrical cord is attached to the generator bracket assembly, between the generator and the windshield washer fluid tank. With the headlamps closed, route the cord in the opening between the headlamp door and the fender panel on the driver's side of the vehicle. Do not pinch the cord when closing the hood. 3. Plug it 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 in the area where you will be parking your vehicle. The dealer can give you the best advice for that particular area. {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. 2-24
