Review BORGWARNER Borg Warner Choke Thermostat

The Borg Warner TH-100 choke thermostat is an essential automotive component designed to regulate the choke system in older carbureted engines. This thermostat plays a critical role in ensuring a smooth and efficient cold start by controlling the amount of fuel and air mixture delivered to the engine.

The TH-100 choke thermostat is a vacuum-operated device with a bimetallic element at its core. This element responds to engine temperature changes and opens or closes the choke plate accordingly. When the engine is cold, the thermostat allows the choke plate to remain open, allowing richer fuel mixture into the carburetor for easier starting. As the engine temperature rises, the thermostat closes the choke plate, allowing the engine to run leaner for better fuel efficiency and reduced emissions.

The Borg Warner TH-100 choke thermostat is made from high-quality materials, including brass and stainless steel, ensuring durability and longevity. Its vacuum-operated design allows it to work seamlessly with the engine's vacuum system and requires minimal maintenance.

This thermostat is an essential replacement part for older vehicles with carbureted engines that experience difficulty starting in cold weather. Installing a new Borg Warner TH-100 choke thermostat can help improve the vehicle's starting performance, reduce fuel consumption, and enhance overall engine performance.

The TH-100 choke thermostat comes with a gasket and is available in various vacuum hose connections to fit different engine applications. It is easy to install and can be done by most DIY automotive enthusiasts or professional mechanics. If you are experiencing cold start problems with your older carbureted vehicle, consider replacing the choke thermostat with a new Borg Warner TH-100 model.
