ABSTRACT:
A simplified, yet highly effective, engine heating apparatus and method is provided which facilitates starting of a cold automotive engine by preheating the engine with hot antifreeze from a fluid-cooled service engine temporarily coupled to the cold engine; in this manner, the cold engine can be heated prior to attempts at starting so that damage to the battery, starter or other internal components thereof is eliminated. In preferred forms, the apparatus includes fluid-conveying conduits permanently coupled to the cooling systems of the cold and service engine and normally detachably secured together to define respective closed fluid loops with the associated engines, along with transfer conduits which can be quickly and easily connected through the use of quick-couplers between the disconnected engine conduits to establish fluid communication between the separate engine cooling systems. Running of the hot service engine thus circulates hot antifreeze through the cold engine block and serves to heat the cold antifreeze to permit quick starting of the engine.
