Fleece Coolant Bypass Manual Transmission (FPE-CLNTBYPS-CUMMINS-MAN) for 2003-2007 Cummins 5.9L

The Fleece Coolant Bypass for Manual Transmission (FPE-CLNTBYPS-CUMMINS-MAN) is a high-performance aftermarket upgrade designed specifically for 2003–2007 Dodge Ram trucks equipped with the 5.9L Cummins diesel engine and a manual transmission. This coolant bypass kit addresses a common issue in Cummins engines where the rear cylinders receive inadequate coolant flow, leading to elevated temperatures and potential long-term engine damage. By rerouting coolant from the rear of the engine, the Fleece bypass ensures more balanced temperature distribution across all cylinders, improving thermal management and engine longevity. Engineered for durability and easy installation, it includes all necessary hoses, fittings, and hardware, making it a popular choice among Cummins enthusiasts seeking improved reliability and performance in demanding conditions.
