This patent describes a vehicle having a main internal combustion engine for driving the vehicle and an electrical system and having a main liquid cooling system connected to the main engine and having fluid passage means for circulating liquid coolant of the cooling system through the engine block of the main engine. The vehicle has an operating compartment and further has a vehicle heating system selectively actuable for providing heat to the operating compartment from the main engine cooling system. The combination consists of an auxiliary internal combustion engine, an auxiliary liquid cooling system connected to the auxiliary engine and connected to the main liquid cooling system, heat transfer means selectively actuable for connecting the vehicle heating system to the auxiliary liquid cooling system for transferring the heat absorbed from the auxiliary engine to the vehicle compartment heating system. The heat transfer means is selectively actuable to a first condition to circulate the liquid coolant for the auxiliary cooling system to the compartment heating system and blocking flow from the auxiliary cooling system to the engine block via the fluid passage means. The heat transfer means is selectively actuable to a second condition to circulate the liquid coolant of the cooling system from the heat exchanger to the engine block via the fluid passage means.
