2003-2007 Cummins M/T Coolant Bypass Kit (FPE-CLNTBYPS-CUMMINS-MAN)

Fits

The Cummins is a great motor that has a proven track record in making power and being reliable, but they still have some shortcomings that the aftermarket has found ways to solve! This Fleece coolant bypass kit moves coolant to the rear of the motor where high temperatures and pressure can build causing reliability and longevity issues. This excessive pressure builds 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. This fleece 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.
