Abstract
An engine pre-heater system 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 an electric heating element is inserted therein, the heating element projecting 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. The engine pre-heater system is also operably able to heat the coolant, engine oil and transmission oil, therefore heating the coolant and warming the engine in a faster and more efficient manner for quick start-ups.
