Abstract
An apparatus and method for heating a dead, cold, fluid cooled internal combustion engine which includes the use of another internal combustion engine with a cooling system having heated coolant circulated by a circulation pump and transferring the heated coolant to the cold engine cooling system. The apparatus includes three male quick couplings communicating with the cooling system and rigidly attached to each engine and a pair of coolant transfer conduits with female quick couplings at both ends. The male quick couplings are connected by the transfer for conduits and the heated coolant is transferred to the cold, dead engine and back to the hot service engine to be warmed up again. Either engine may be used as the hot service engine or can receive heated coolant from a hot service engine.
