Detailed Product Description
The Hygrade CV350 carburetor choke thermostat is tailored for GM carburetors used in a range of vehicles such as the Buick LeSabre, Cadillac Fleetwood, Chevrolet Caprice, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix models. This thermostat controls the choke mechanism by sensing temperature changes, allowing the choke to open and close at the correct times during engine warm-up. Unlike electric assist thermostats, the CV350 operates mechanically, providing a reliable and maintenance-friendly solution for carburetor choke control.

Installation Notes and Tips
- Ensure compatibility with your specific GM carburetor model before installation
- Remove the old choke thermostat carefully to avoid damage to the carburetor linkage
- Verify that the thermostat moves freely and is properly aligned with the choke plate
- Test choke operation by observing choke plate movement during engine warm-up
- Consult vehicle service manual for torque specifications and detailed installation procedures
