A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 5.9L/6.7L cooling system with a Mishimoto Dodge 5.9L/6.7L Cummins Low-Temperature Thermostat! This Cummins performance thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a lower activation temperature (180°F) compared to the factory thermostat (190°F for 99-10 and 2013 trucks & 200°F for 10-12 trucks).

The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This Cummins performance thermostat is ideal for use in warmer climates or under extreme towing/driving conditions.
