An improved engine cooling system is combined with an automotive air conditioning system for utilizing otherwise waste heat from an engine to vaporize refrigerant fluid which is condensed and pumped back to the engine in a closed cycle. In a cooling mode, vaporized refrigerant is conveyed via a jet ejector to the automobile radiator, a condensed portion of the refrigerant fluid being drawn by the ejector through a throttling valve and a conditioner air coil to provide evaporative cooling. In a heating mode, the vaporized refrigerant is conveyed directly to the conditioner air coil, which then serves as a condenser to provide condensation heating. The partially condensed refrigerant is further condensed at the radiator and then pumped back to the engine.
