A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 5.9L cooling system with a Mishimoto Dodge 5.9L Cummins Low-Temperature Thermostat! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a lower activation temperature (174°F) compared to the factory thermostat (180°F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing/driving conditions.
