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-SS uses a temperature-actuated secondary thermostat to improve coolant flow at the rear cylinders, helping maintain more consistent temperatures across all six cylinders. The stainless steel braided bypass line and AN O-ring fittings provide a durable, leak-resistant installation while helping reduce excessive coolant pressure that can lead to freeze-plug failures.
