About this part
The 12-valve first-gen Cummins in your Ram is considered one of the best diesel engines ever produced and for good reason. Fuel efficiency torque and simplicity are just a few characteristics that give the Cummins its stellar reputation. We're huge fans of the Cummins engine which is why we've developed a high-temperature thermostat for the 1989-1993 5.9L 12v Cummins. This Mishimoto thermostat activates at a higher temperature (189.5F) compared to the factory thermostat (180F). By raising the activation temperature coolant flows through the system later promoting quicker engine warmup. The Mishimoto high-temperature thermostat is ideal for vehicles in cold climates where rapid warmup and quicker in-cabin heat is vital. This thermostat includes a high-quality replacement gasket and our signature Mishimoto Lifetime Warranty.
