ABSTRACT:
An auxiliary liquid cooling system for snowmobiles that is easily adapted as an aftermarket item and provides both auxiliary engine cooling capacity and added operator warmth. The auxiliary cooling system consists of a small automotive type radiator mounted along one or both sides of a snowmobile drive tunnel in a position just above the front operator footrests. The engine cooling liquid flows through the radiators in addition to the factory heat exchangers adding extra cooling capacity. The turbulence created by the rotating clutch and drive members aid the airflow through the radiators and cause the warmed air to be directed toward the operator.
