This Coolant Bypass kit from Fleece Performance routes additional coolant to the rear of the block on 2003-2007 Dodge Ram 2500/3500 5.9L 24V Cummins, where factory flow is weakest and coolant temperatures run highest.
Key Features
- Secondary thermostat operates on temperature rather than pressure, so flow increases before pressure becomes a problem
- Increases coolant flow to the rear cylinders and lowers coolant temperature there
- Helps prevent the pressure build-up that pushes out external freeze plugs and the smaller plugs under the valve cover
- AN O-ring fittings and stainless steel braided hose for a leak-free installation
Fitment
2003-2007 Dodge Ram 2500/3500 5.9L 24V Cummins with manual transmission.
Manual transmission trucks do not use a transmission fluid heat exchanger, so no additional parts are required.
Model years covered: 2003, 2004, 2005, 2006, 2007.
