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 warmup, 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.
Mishimoto Automotive (“Mishimoto”) warrants its products under this lifetime limited warranty policy (“Warranty Policy”). This Warranty Policy applies solely to: (i) Mishimoto Products purchased directly from Mishimoto or Mishimoto authorized dealers (each a “Mishimoto Product” and collectively, the “Mishimoto Products”) and (ii) the original purchaser of such Mishimoto Product (“Purchaser”). This Warranty Policy is non-transferable and all claims under this Warranty Policy must be accompanied by the original sales receipt. The terms and conditions of this Warranty Policy are subject to change by Mishimoto at any time without notice.
