Installation of the Carter AC238S is a straightforward process for those with some automotive experience. The thermostat simply replaces the existing thermostat in the engine cooling system. It is recommended to follow the manufacturer's instructions carefully to ensure proper installation and to prevent any potential damage to the engine.

In summary, the Carter AC238S Carburetor Climate Control Choke Thermostat is an essential component in the engine heating system of carbureted engines with part numbers 170 and 170-308. Its durable design and ability to regulate coolant flow based on engine temperature make it an invaluable addition to any engine, especially in colder climates. With proper installation, this thermostat can help ensure efficient engine performance and a comfortable cabin temperature.
