Air Cleaner - Thermostatic: Description
The Thermostatic Air Cleaner controls the temperature of the air entering the carburetor so more accurate carburetion can be achieved, giving better combustion and emission control. The thermostatic air cleaner consists of the air cleaner housing with an intake air snorkel, air flow control door and temperature sensing device.
On 626 models, a vacuum diaphragm linked to the air flow control door is controlled by a thermo sensor valve mounted to the base of the air cleaner. B2000 and GLC models use a bi-metallic thermostatic device attached to air flow control door in snorkel to regulate incoming air.
