Airtex 2C1098 Carburetor Choke Thermostat

The Airtex 2C1098 carburetor choke thermostat is a critical component for carbureted engines, automatically regulating the air-fuel mixture during cold starts and engine warm-up. This thermostat replaces Standard Motor Products CV329 and fits various Buick, Checker, Chevrolet, GMC, Oldsmobile, and Pontiac vehicles equipped with carburetors.

How It Works:

The choke thermostat uses a bi-metallic coil that expands and contracts with temperature changes to control the carburetor's choke valve. When the engine is cold, the thermostat keeps the choke valve closed, restricting airflow to create a richer fuel mixture necessary for cold starting. As the engine warms up, the bi-metallic coil heats up and gradually opens the choke valve, allowing more air into the carburetor for optimal performance at operating temperature.

Key Features:

• Direct replacement for Standard Motor Products CV329
• Precision-calibrated bi-metallic coil for accurate choke operation
• Ensures proper air-fuel mixture during cold starts and warm-up
• Helps prevent hard starting, rough idle, and excessive fuel consumption
• Quality construction for reliable, long-lasting performance
