Fits 1994-1998 Dodge Ram 2500 and 3500 (5.9L / 6.7L Cummins).

The rear cylinders on the Cummins engine platform often suffer from restricted coolant flow, leading to localized hot spots and excessive cooling system pressure. If left unaddressed, this pressure can result in catastrophic failure by blowing out external freeze plugs or the smaller plugs located under the valve cover. The Fleece Performance Coolant Bypass Kit is a proactive solution designed to improve the reliability and longevity of your engine.

Unlike other kits that rely on pressure-activated valves, this kit utilizes a secondary thermostat that operates based on temperature. This design ensures consistent coolant flow across all six cylinders, resolving temperature imbalances before damaging pressure builds up. It is a vital upgrade for high-horsepower applications or vehicles operating in demanding environments.

  • Lowers coolant temperatures at the rear cylinders
  • Ensures consistent temperature distribution across the entire block
  • Prevents damaging pressure buildup that leads to freeze plug failure
  • Includes high-quality braided hose and AN O-ring fittings for a leak-free seal
  • Manufacturer Part Number: FPE-CLNTBYPS-CUMMINS-12V
