Mishimoto High-Temperature Thermostat - 1999-2013 Dodge 5.9L/6.7L Cummins

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 High-Temperature Thermostat! This Cummins performance thermostat is designed as a direct-fit replacement for your aged factory unit.
The Mishimoto thermostat has a higher activation temperature (205°F) compared to the factory thermostat (190°F for 99-10 and 2013 trucks & 200°F for 10-12 trucks). The higher activation temperature restricts coolant flow longer to allow a quicker engine warm-up, making this Cummins performance thermostat ideal for use in cold climates.
