Built to correct a known weak point in the Cummins cooling system, this Fleece Performance Coolant Bypass kit fits 2019-2024 Ram 2500/3500 6.7L Cummins and evens out coolant temperature from front to rear.

Key Features

  • Secondary thermostat operates on temperature rather than pressure, so flow increases before pressure becomes a problem
  • Increases coolant flow to the rear cylinders and lowers coolant temperature there
  • Helps prevent the pressure build-up that pushes out external freeze plugs and the smaller plugs under the valve cover
  • AN O-ring fittings and black braided nylon hose for a leak-free installation

What's Included

  • Rear thermostat housing
  • Front thermostat housing
  • New EGR cross-over tube gaskets
  • Black braided nylon coolant bypass hose with AN fittings
  • Mounting hardware
