1994-1998 Cummins Coolant Bypass Kit (FPE-CLNTBYPS-CUMMINS-12V)

Description

Fits

The rear cylinders on the 5.9 & 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. The Fleece Performance coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before the pressure becomes an issue by ensuring consistent temperatures across all six cylinders. You will receive an increase in coolant flow and a decrease in coolant temperatures. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.
