The Mishimoto MMTS-RAM-94H High Temperature Thermostat for your 1998.5-2013 Dodge 5.9L/6.7L Cummins is an excellent option for those in colder climates. 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 Cummins High-Temperature Thermostat! This 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 9910 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 thermostat ideal for use in cold climates. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
