This thermostat is specifically designed for use with carbureted engines, making it a valuable find for enthusiasts and restorers seeking authentic replacement parts for their classic vehicles.

The CM-3680 Carburetor Choke Thermostat is an essential element of the engine's starting system, as it regulates the temperature of the choke circuit to ensure a smooth and efficient cold start.

This Motorcraft part is meticulously crafted to meet the highest quality standards. It features a robust, durable design with a precision-engineered thermostat housing, ensuring reliable and consistent performance even after prolonged use. The CM-3680 is designed to fit select Ford and Mercury vehicles from the 1981 model year, including but not limited to:
