Fleece Performance Engineering Cummins Coolant Bypass Kit
Keep your Cummins engine cooling system pressure's down!

Increased Coolant Flow Decreased Coolant Temperatures
The rear cylinders suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the system, especially the rear of the block and possibly blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Fleece has designed their coolant bypass kit with a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders

Features:

  • 03-07 5.9 auto trucks will have to remove the trans fluid heat exchanger that isn't needed in warmer climates
  • Complete kit
  • Relieves coolant pressure build up
  • Lowers coolant temperature to the rear cylinders
  • Great for mild to wild power trucks
