Improve cooling-system reliability on your 1994-1998 Dodge Ram 2500 or 3500 5.9L 12-valve Cummins with the Fleece Performance Coolant Bypass Kit. Part FPE-CLNTBYPS-CUMMINS-12V adds a temperature-actuated secondary thermostat to improve coolant circulation at the rear cylinders, helping maintain more consistent temperatures across all six cylinders. By reducing excess coolant pressure at the rear of the engine, this kit helps protect against freeze-plug failures and supports long-term Cummins reliability.
