Thermostatic Air Cleaner: Description

Air cleaner is equipped with an air control valve (inside snorkel) which allows either heated exhaust shroud air or cooler ambient air into carburetor, depending on valve position. Valve position is controlled by a vacuum motor which responds to a bimetal temperature sensor, located inside air cleaner housing, on all models except Champ and Colt (FWD). On Champ and Colt (FWD), a bimetal sensor, located at hinge of control valve, sets valve position.
