Product Details

The Mishimoto High-Temperature Thermostat is a direct-fit replacement engine coolant thermostat for Dodge Cummins diesel engines. It replaces an aged factory unit and helps keep the cooling system reliable. A defective thermostat can lead to overheating and potential internal engine damage.

Key Features:

  • Higher activation temperature than the factory thermostat. This restricts coolant flow for longer, so the engine warms up more quickly.
  • Suited to cold climates, where faster warm-up and quicker in-cabin heat matter.
  • Direct-fit design installs in place of the factory thermostat. Mishimoto rates installation difficulty as easy.
  • Mishimoto Lifetime Warranty backs the product's quality and craftsmanship.

Mishimoto builds Cummins performance cooling parts with the aim of improving cooling system reliability. Choose the option in this product line that matches your engine to get a direct-fit thermostat with a higher opening temperature than stock.
