FLEECE FPE-CLNTBYPS-CUMMINS-VP-SS CUMMINS COOLANT BYPASS KIT VP 98.5-02 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+ 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 (VP 98.5-02) for Cummins 5.9/6.7L engines is an essential enhancement for those striving for optimal performance and reliability. Crafted specifically for 1998-2002 Dodge Ram 2500 and 3500 models, this innovative kit addresses a critical issue: insufficient coolant flow to the rear cylinders. As these cylinders are notorious for experiencing elevated temperatures, the Fleece Bypass Kit effectively mitigates the risk of catastrophic failures often associated with excessive coolant pressure.
  
  By integrating a secondary thermostat that operates based on temperature instead of pressure, the kit ensures a more efficient cooling process. This prevents the build-up of dangerous coolant pressure that can lead to blown freeze plugs, safeguarding against engine damage and extending the lifespan of your vehicle. The Fleece Coolant Bypass guarantees lower coolant temperatures at the rear cylinders, resulting in consistent operating temperatures across all cylinders, promoting overall engine health.
  
  Installation is straightforward with the complete kit, featuring a durable stainless steel braided line and AN O-ring fittings to ensure a leak-free experience. For model years 2003 and later, included billet hose brackets enhance the overall structural integrity of the installation.
  
  Drivers seeking improved durability and performance for their Cummins engine will find the Fleece Coolant Bypass Kit a vital upgrade. With the assurance that all cylinders will be adequately cooled, this kit stands out as one of the most significant modifications for enhancing the reliability of the Cummins platform. Make a sound investment in your truck’s longevity and performance with this key coolant management solution. Experience peace of mind knowing your engine is operating at peak efficiency, reducing the risks associated with high-pressure coolant scenarios.
