FLEECE FPE-CLNTBYPS-CUMMINS-19 COOLANT BYPASS KIT FOR 2019-PRESENT RAM WITH 6.7L CUMMINS

Just in time for Summer! Our all-new Fleece Performance coolant bypass for the 2019-Present RAM with 6.7L Cummins! Our patent pending design seamlessly integrates with your truck for an OE fit-and-finish.

Features:

• Increased Coolant Flow, Decreased Coolant Temperatures
• The rear cylinders on the 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.

Why do I need a Fleece Coolant Bypass?
One of the biggest issues on the 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.

Kit Includes:

• Rear coolant bypass thermostat housing
• Front coolant bypass thermostat housing
• New EGR cross-over tube gaskets
• Black braided nylon coolant bypass hose with AN fittings
• Mounting hardware

Warranty:

• 1 Year Limited Parts Warranty

  The Fleece Performance Coolant Bypass Kit for the 2019-Present RAM 6.7L Cummins provides an essential upgrade to your truck's cooling system, particularly addressing the common issue of inadequate coolant flow to the rear cylinders. Designed with a patent-pending technology, this kit ensures a seamless integration with your vehicle, delivering both outstanding performance and an OE fit-and-finish.
  
  This innovative coolant bypass system features a secondary thermostat that is uniquely engineered to operate based on temperature rather than excessive pressure. By effectively managing coolant flow, it prevents the detrimental buildup of pressure that can lead to catastrophic failures, such as blown freeze plugs. These common issues arise due to high temperatures in the rear cylinders; however, with the installation of the Fleece Coolant Bypass Kit, you can expect notable reductions in coolant temperatures, effectively enhancing the longevity and reliability of your engine.
  
  Included in the kit are all the necessary components for a complete installation: the rear and front coolant bypass thermostat housing, new EGR crossover tube gaskets, and a black braided nylon coolant bypass hose with AN fittings. Each component is designed to ensure a leak-free experience and is accompanied by mounting hardware for straightforward setup.
  
  With detailed fitment for various RAM models from 2019 to 2022, including the Big Horn, Laramie, Limited, and more, this coolant bypass kit is a crucial addition for any serious Cummins enthusiast. With a 1-year limited parts warranty backed by Fleece Performance, peace of mind accompanies your investment in a solution to one of the most pressing challenges facing 6.7L Cummins engines today. Elevate your vehicle’s cooling capabilities and safeguard your engine with this essential enhancement.
