Description

A thermostat is a crucial component of a truck’s cooling system that regulates the engine temperature. The 3946849 thermostat is specifically designed for use in certain types of trucks and works by opening and closing to allow or restrict coolant flow to the radiator. This action helps maintain a constant operating temperature for the engine, which improves fuel efficiency, prevents overheating, and reduces emissions. When the engine is cold, the thermostat remains closed, allowing it to warm up quickly. Once it reaches its optimal operating temperature, the thermostat opens and allows coolant to circulate through the system. If the thermostat fails or becomes stuck in either an open or closed position, it can cause problems such as poor fuel economy, reduced power output, or even engine damage due to overheating.Hawks Parts is a professional Cummins parts wholesale supplier in China, We can provide Genuine/Original, OEM, and aftermarket Cummins parts as well as a one-stop service for you.
