Mishimoto Low-Temperature Thermostat for 1999-2013 Dodge/Ram 2500/3500 (5.9L / 6.7L)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1999-2013 Dodge and Ram 2500/3500 trucks (5.9L / 6.7L Cummins).
The Mishimoto Low-Temperature Thermostat provides a proactive approach to cooling for your Cummins-powered Dodge or Ram truck. Designed to activate at a lower temperature than the factory unit, this thermostat allows coolant to circulate through the radiator earlier. This prevents the engine from reaching higher peak temperatures, which is especially critical when towing heavy loads or operating in hot climates.
This component serves as a direct-fit replacement for the OEM unit, ensuring a clean installation into the factory housing. By maintaining lower overall engine temperatures, it helps reduce the risk of heat-related component wear and improves thermal efficiency during high-demand operation.
- Lower activation temperature allows for earlier coolant flow through the system
- Maintains cooler engine temperatures under high-load or high-ambient conditions
- Direct-fit replacement for factory thermostat
- Ideal for heavy towing, hauling, and warm climate operation
- Manufacturer Part Number: MMTS-RAM-99L
