Fleece Stainless Steel Hose Coolant Bypass Kit CLNTBYPS-12V-SS

The Fleece CLNTBYPS-12V-SS Stainless Steel Hose Coolant Bypass Kit from is what your 1994-1998 Dodge 5.9L Diesel needs today. The Fleece FPE-CLNTBYPS-12V-SS Coolant Bypass Kit is a must-have on any high-performance Diesel Engine. The engine's cooling system was designed to adequately cool a 300-350hp engine. When horsepower is increased there is also an increased demand on the cooling system. The rear cylinders suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the system, especially the rear of the block and possibly blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure.

The Fleece FPE-CLNTBYPS-12V-SS Coolant Bypass Kit has a secondary thermostat (180 degrees), that, unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. Our kit comes with high-quality leak-free O-ring fittings and AN hose connections with stainless steel braided hose to ensure a leak-free installation.
