-8- ABSTRACT This invention relates to systems devised to rapidly heat an engine to facilitate the starting thereof. Substantial reduction in vehicle operator effort, in size and quantity of structure required, and in reliance upon moving parts of an engine for actuation of a device, are provided by the invention. An accumulator reservoir (26) is coupled to an insulated fluid storage reservoir (28) which in turn is coupled to the engine cooling system. A circuit (51) opens the valve structure (31), the accumulator (26) forcing fluid coolant out of the reservoir (28) into the cooling system, the circuit (51) disabling ignition of the engine until the coolant system is filled. Upon shut-down of the engine, the circuit (51) after a time delay operates a pump (41) to move the coolant back into the reservoir (28) where the coolant is stored at an elevated temperature.
