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 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 (190°F) compared to the factory thermostat (180°F). 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.
