To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. On the 2.4L L4 ECOTEC® engine, the engine coolant heater cord is located near the air cleaner box on the passenger' side of the engine compartment. On the 3.5L, 3.6L and 3.9L V6 engines, the engine coolant heater cord is located on the driver side around the battery box. See Engine Compartment Overview on page 5-14 for more information on location. 3. Plug the cord into a normal, grounded 110-volt AC outlet. { 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. 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 your vehicle for the best advice in this. 2-25
