Abstract: An apparatus for heating a cold engine includes a cylinder band heater, a battery heater, an oil sump heater, and a wiring harness. The cylinder band heater includes a heating element, a tightening device, and a cylinder electrical connector. The tightening device is preferably a hose clamp, but could be any other type of tightening device which may be securely fastened around a cylinder. The heating element is attached to either the inside or outside of the tightening device with preferably some type of adhesive. A thermostat may be on the wiring harness. A battery heater includes a battery heater element, and a battery electrical connector. A thermostat is preferably included between the wiring harness and the battery heater to keep the temperature relatively constant. The wiring harness includes a power cord which is suitable for mating with an extension cord. The wiring harness preferably provides a connection to at least one cylinder band heater, a battery heater, and an oil sump heater.
