The Fleece FPE-CLNTBYPS-CUMMINS-MAN Coolant Bypass Kit addresses the common issue of poor coolant flow to the back cylinders in your 2003-2007 Dodge Ram 5.9L Cummins with manual transmission. As you add performance parts to your stock engine, the factory cooling system can no longer supply the demand for the increased heat that's generated. When coolant temperature increases, pressure begins to build to critical levels, potentially blowing the freeze plugs out on the engine block which can cripple your truck!

By designing their coolant bypass kit with a temperature activated thermostat, the pressure never reaches damaging levels and ensures consistent temperatures across all six cylinders. Included with the kit are high quality O-Ring fittings and AN hose connections with your choice of braided black nylon or braided stainless steel hose for a secure, leak-free installation.
