ABSTRACT:
A method of installing an engine block heater includes the provision of an O-ring carried by the cylindrical body of the heater. The heater also includes a flange portion with a passage therein. The engine block wall is provided with a threaded opening located adjacent to the typically found aperture in the engine block. The heater can be easily installed by aligning the passage in the heater flange with the opening in the engine block and then inserting the body into the aperture such that the O-ring seal engages the aperture wall to provide a sealing engagement therebetween. The heater can be secured by way of a fastener passing through the flange passage which is threaded into the engine block opening.
