Review CARTER Carburetor Choke Thermostat Bwd

The Carter 170-1270 carburetor choke thermostat is a crucial component in the starting system of your vehicle, specifically designed for use in Chrysler Throttle Body Drive (TBD) systems with the Throttlebody 99 series engine, such as those found in certain Jeep models. This thermostat plays an essential role in regulating the temperature of the engine coolant that flows through the carburetor during engine starting.

The Carter 170-1270 is a mechanical thermostat, meaning it uses a bimetallic strip to expand and contract in response to changing temperatures. When the engine coolant temperature drops below a certain threshold during cold starts, the thermostat allows the thicker, unmixed choke fuel to flow into the carburetor, enriching the air-fuel mixture for easier engine ignition. Once the engine temperature reaches a certain point, the thermostat closes, allowing the normal, thinner fuel mixture to flow through the carburetor.

This thermostat is constructed of high-quality materials, ensuring durability and reliability. Its brass housing is corrosion-resistant and can withstand the harsh conditions of an engine bay. The bimetallic strip is made of precise, heat-treated metals, allowing for accurate temperature sensing and control.

The Carter 170-1270 carburetor choke thermostat features an easy-to-install design, with simple bolt-on mounting and no special tools required. It is also compatible with OEM (Original Equipment Manufacturer) gaskets, making installation even more straightforward.

In summary, the Carter 170-1270 carburetor choke thermostat is a vital component in the starting system of Chrysler TBD engines. Its unique design enables it to regulate the temperature of the engine coolant flowing through the carburetor during cold starts, ensuring easier engine ignition and improved overall performance. Constructed of high-quality materials, this thermostat offers durability, reliability, and easy installation.
