    Product Details

    Coolant Bypass by Fleece Performance Engineering®. For 2003-2007 Manual Transmission w/ Stainless Steel Braided Line. The rear cylinders on the 5.9L 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. 1 Year Limited Parts Warranty.

    Why do I need a Fleece Performance Coolant Bypass?

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