Description
This item is brand-new, factory sealed.
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 (205F) compared to the factory thermostat (190F for 99-10 and 2013 trucks; 200F 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.Direct fit for 1999-2013 Dodge Ram with 5.9L/6.7L Cummins Higher activation temp restricts coolant flow for quicker engine warm-up Ideal for use in cold climates Mishimoto Activation: 205F (96C) / OEM Activation: 190F (87.5C) Mishimoto Lifetime Warranty
