The complete kit includes high-quality AN O-ring fittings and AN hose connections with a braided hose to guarantee a leak-free installation. Professional installation is recommended.

It enhances the reliability and longevity of your 6.7 Cummins engine, eliminating the risk of scored rear cylinders and blown freeze plugs.

Description

Product Features:

  • Lowers coolant temperature at the rear cylinders
  • Ensures consistent temperatures across all cylinders
  • Prevents damaging coolant pressure build-up
  • The complete kit comes with a braided hose and AN O-ring fittings to ensure a leak-free installation

One of the biggest issues fit for the 5.9L/6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blowouts of the freeze plugs in an over-temperature / over-pressure condition. The Coolant Bypass is one of the most important additions you make to improve the reliability and longevity  fit for the Cummins platform.

The rear cylinders fit for the 5.9L/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block, and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Our coolant bypass kit adds 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.
