Fleece Coolant Bypass Kit for 1998.5-2002 Dodge Ram 5.9L VP Cummins
FPEFPE-CLNTBYPS-CUMMINS-VPHave a 24 valve VP44 truck? The rear cylinders run hotter than the rest, and this bypass fixes that.
The 5.9/6.7L Cummins has a known coolant flow problem at the rear cylinders, which run the highest temperatures. Pressure builds at the rear of the block and can blow out freeze plugs externally or the smaller plugs under the valve cover. Fleece's secondary thermostat works on temperature instead of excessive pressure, solving the problem before pressure becomes an issue and keeping all six cylinders consistent.
Benefits
- Lowers coolant temperature at the rear cylinders
- Ensures consistent temperatures across all cylinders
- Prevents damaging coolant pressure build up
- Braided hose and AN O-ring fittings for a leak-free install
