FLEECE FPE-CLNTBYPS-CUMMINS-12V-SS CUMMINS COOLANT BYPASS KIT 12V 94-98 WITH STAINLESS STEEL BRAIDED LINE

Increased Coolant Flow, Decreased Coolant Temperatures. The rear cylinders on the 5.9/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures.

This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure.

Our coolant bypass kit adds a secondary thermostat, 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.

Benefits:

• Lowers coolant temperature at the rear cylinders
• Ensures consistent temperatures across all cylinders
• Prevents damaging coolant pressure build up
• Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation.
• Kits for MY 2003 and up include billet hose brackets.

Why do I need a Fleece Coolant Bypass?
One of the biggest issues on the 5.9/6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.
Application Notes:

• The 2003 - 2007 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed.
• For model years 2007 - 2018 6.7L trucks, including both automatic and manual equipped transmissions, factory installed transmission fluid heat exchangers are uncommon. For customers with a 6.7L that has a heat exchanger, a heater tube can be purchased at your local Chrysler Dealership [PN:68048997AA] to complete the installation.

  The Fleece Coolant Bypass Kit (FPE-CLNTBYPS-CUMMINS-12V-SS) is an essential upgrade for 1994-1998 Dodge Ram 2500 and 3500 models equipped with the 5.9L and 6.7L Cummins engines. Designed to enhance the performance and reliability of your vehicle's cooling system, this kit directly addresses one of the most problematic issues known in these engines: inadequate coolant flow to the rear cylinders.
  
  High temperatures in the rear cylinders can lead to excessive pressure in the cooling system, often resulting in catastrophic failures, including blown freeze plugs and increased chances of engine damage. The Fleece Coolant Bypass Kit alleviates this by incorporating a secondary thermostat that reacts to temperature variations rather than pressure, ensuring a balanced and reliable coolant distribution across all cylinders.
  
  Highlighted features include significantly lowered coolant temperatures at the rear cylinders, which promotes engine longevity and prevents damaging pressure buildup. The complete kit includes a stainless steel braided hose and AN O-ring fittings, ensuring a seamless, leak-free installation. For model years 2003 and above, enhanced with billet hose brackets, the installation process becomes even more streamlined.
  
  The Fleece Coolant Bypass is not merely an accessory but a vital enhancement for maintaining engine integrity and performance. It offers peace of mind for users who rely on their trucks, especially in high-performance or challenging driving conditions. Whether you're a daily driver or a high-performance enthusiast, investing in this bypass kit means ensuring the reliability and efficiency of your Cummins engine for years to come. Experience enhanced cooling performance and safeguard your engine with the Fleece Coolant Bypass Kit today.
