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 (205ยฐF) compared to the factory thermostat (190ยฐF for 99โ10 and 2013 trucks & 200ยฐF 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. As with all our Cummins performance parts, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
Features:
- Direct fit for 1999โ2013 Dodge Ram with 5.9L/6.7L Cummins

- Ideal for cool climates
