Mishimoto MMTS-RAM-99L – Dodge 5.9L/6.7L Cummins Low-Temperature Thermostat

A defective thermostat can result in engine overheating and potential internal damage. This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a lower activation temperature 180F compared to the factory thermostat 190F for 99C10 and 2013 trucks 200F for 10C12 trucks. The lower activation temperature allows coolant to flow through the engine earlier which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing/driving conditions.
