A heating element for use in an engine pre-heater comprising a housing having a passage extending therethrough for passage of coolant through the pre-heater. The housing provides at least one opening defined therein separate from the passage, and the heating element is inserted vertically therein, projecting downwardly into the passage whereby the heating element is in direct contact with the coolant to heat it. The heating element is supplied with electrical power from a power source for enabling it to heat the coolant, and a lower end of the heating element is L-shaped, the lower end thus being substantially perpendicular in relationship to the remainder of the heating element, giving the heating element a greater surface area with which to contact, and thus heat the coolant.
