ABSTRACT:
A cooling system for a water cooled engine provides increased heating capacity on cold starts and prevents icing of the throttle body. This is achieved by preheating the cooling water delivered to the throttle body and a heater core with a heating device. The heating device includes a first housing for passing the cooling water from the engine to the throttle body and the heater core, and a second housing disposed around the first housing to form an exhaust passage between the first and second housings. An exhaust gas control device selectively passes exhaust from the engine to the exhaust passage of the heating device to heat the cooling water. The exhaust from the engine is passed to the heating device as a function of when the cooling water temperature.
