Product Description Reviews
Description:

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 (189.5¡ãF) compared to the factory thermostat (180¡ãF). 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.

Features:

  • Direct fit for 1989-1993 Dodge Ram with 5.9L Cummins
  • Higher activation temperature restricts coolant circulation for a longer time, providing quicker engine warmup
  • Ideal for cold climates
  • Includes thermostat and high-quality replacement gasket

  • (1) Mishimoto Thermostat
