Mishimoto Dodge 5.9L/6.7L Cummins Low-Temperature Thermostat

When you're working on your 1999-2010 Dodge Ram 2500 with a 5.9L or 6.7L Cummins engine, a reliable cooling system is key. This Mishimoto thermostat is a direct-fit replacement for your stock unit, designed to help manage engine temperatures more effectively. It opens at a lower temperature, allowing coolant to circulate sooner and keep your engine running cooler, which is especially beneficial in warmer climates or when you're putting the truck to work with heavy towing.

Unlike the factory thermostat, which typically opens around 190-200 degrees Fahrenheit depending on the year, this Mishimoto unit activates at 180 degrees Fahrenheit. This earlier opening means coolant flows through the radiator sooner, helping to reduce and maintain lower overall engine temperatures. It's a straightforward way to improve the cooling system's performance, especially if you've noticed your truck running a bit warm under load or in hot weather.

This thermostat is a solid option for anyone looking to enhance their Cummins engine's reliability. It's designed to install just like the original, making it a practical upgrade for your cooling system.
