The Fleece Performance coolant bypass kit is designed specifically for the 2013-2018 Dodge Ram 2500 / 3500 with the 6.7L Cummins engine, offering a seamless integration for an OE fit-and-finish. This comprehensive kit addresses the common issue of insufficient coolant flow to the rear cylinders, which can lead to high coolant temperatures and potential engine damage. The core feature of this kit is the inclusion of a secondary thermostat that operates based on temperature rather than pressure, ensuring consistent cooling for all six cylinders and preventing excessive pressure buildup.

Kit Components and Technical Specifications

The Fleece coolant bypass kit comes with all the necessary components for a complete and leak-free installation. This includes a rear coolant bypass thermostat housing, a front coolant bypass thermostat housing, new EGR cross-over tube gaskets, a black braided nylon coolant bypass hose with protective high temperature sleeve, and AN fittings. Each component is engineered for durability and performance, providing a reliable solution to the coolant flow issue. The kit also includes mounting hardware for easy installation, ensuring a secure and precise fit on your RAM 6.7L Cummins.

Benefits and Applications

The Fleece coolant bypass kit offers numerous benefits for both performance and reliability. It lowers coolant temperature at the rear cylinders, ensuring consistent temperatures across all cylinders, and prevents damaging coolant pressure buildup. These benefits translate to a longer engine lifespan, improved fuel efficiency, and reduced risk of catastrophic failure. This kit is an essential upgrade for any RAM 6.7L Cummins owner looking to enhance the performance and longevity of their vehicle. By addressing the coolant flow issue, the Fleece coolant bypass kit is one of the most important additions you can make to your engine, providing peace of mind on the road.
