March 17 2004. Pre-heating a competition engine before it is used under load is essential. In the past the only way to bring the engine up to optimum operating temperature has been to "run it up" under its own power, but this creates unnecessary wear and tear and uses up valuable engine life.

Now, following research by its design team, Earl's Performance Products has developed a solution to this problem — the new Earl's Engine Pre-Heater System. The pre-heater system raises the coolant temperature from ambient to 80° C in approximately 40 minutes (typical 5 litre water system) — without having to run the engine!

Supplied in a lightweight aluminium case, Engine Pre-Heater System includes a set of female weld bosses to be attached to the water rails either side of the engine. The bosses need to be located in accessible areas to allow easy coupling and decoupling of the dry break fittings supplied. Pro-Lite™ feed and return hoses then connect the thermostatically controlled 200v AC heater/pump unit, contained in the case, to the engine. When the system is switched on the coolant is circulated and heated until it reaches its optimum temperature. The engine need not be started until this time. The pre-heater system can be activated using a timer switch — not supplied — heating the engine before the team mechanics arrive.

This type of system is commonly used in Formula 1, Formula 3000, Formula 3, Sportscars, World Rally and many other categories.

Earl's Engine Pre-Heater System now makes this engine-preserving technology accessible to all levels of motorsport.
