component with tie-straps. The heater warms the engine providing easier engine starting and faster warm-up in low temperatures. The heater is

OPERATION
Connecting the power cord to a grounded 110-120 volt AC electrical outlet with a grounded, three wire extension cord activates the heating element
warming the engine coolant.
