Mishimoto Low Temperature Thermostat for 98.5-13 Dodge Cummins 5.9L/6.7L Diesel MMTS-RAM-99L



The Mishimoto MMTS-RAM-94L Low Temperature Thermostat for your 1998.5-2013 Dodge 5.9L & 6.7L Cummins is a perfect option for those that live in warmer climates. A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your cooling system with a Mishimoto Dodge Cummins Low-Temperature Thermostat. This thermostat is designed as a direct-fit replacement for your aged factory unit.

The Mishimoto thermostat has a lower activation temperature (180°F) compared to the factory thermostat (190°F for 98.5–10 and 2013 trucks & 200°F for 10–12 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. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
