Cummins Coolant Bypass Kit for Enhanced Performance

Experience the ultimate in cooling system efficiency with the Cummins Coolant Bypass Kit. This comprehensive kit is designed to improve coolant flow and decrease temperatures in your 5.9/6.7L Cummins engine. Say goodbye to the common issues faced by rear cylinders, which often suffer from inadequate coolant circulation and high temperatures. This kit is a game-changer for your engine's health and performance.

Advanced Coolant Management System

Our coolant bypass kit features a secondary thermostat that operates based on temperature, not pressure, ensuring consistent temperatures across all six cylinders. This innovative approach prevents excessive pressure build-up and protects your engine from potential failure. The kit includes a braided hose and AN O-ring fittings for a leak-free installation. For models from 2003 and up, we've included billet hose brackets for added durability.

Key Benefits and Applications

The Fleece Coolant Bypass Kit is a vital addition for improving the reliability and longevity of your Cummins engine. With this kit, you can expect to see a significant reduction in coolant temperatures at the rear cylinders, ensuring consistent engine performance. The benefits are numerous, including lower coolant temperatures, consistent temperatures across all cylinders, and prevention of damaging coolant pressure build-up. This kit is perfect for both everyday drivers and enthusiasts looking to optimize their Cummins engine's cooling system. With the kit's ability to eliminate factory transmission fluid heat exchangers and its compatibility with various transmission types, it's a versatile solution for any Cummins owner.
