Fleece Performance Coolant Bypass Kit for 2007.5-2012 Dodge Ram 6.7L Cummins

The Fleece Performance coolant bypass for the 2007.5-2012 RAM with 6.7L Cummins 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 aFleece 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 Braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings Exhaust back pressure sensor mounting block and back pressure sensor line Mounting hardware Recommended Cross Sell Skus - FPE-351-0712/FPE-34560

The Fleece Performance Coolant Bypass Kit for the 2007.5-2012 Dodge Ram with 6.7L Cummins engine is designed to improve cooling efficiency and engine longevity. This comprehensive kit features a secondary thermostat that operates based on temperature, unlike other brands that rely solely on pressure, effectively preventing excessive coolant pressure buildup in the rear cylinders. By ensuring consistent coolant temperatures across all cylinders, this kit significantly reduces the risk of freeze plug blowouts and engine failure caused by overheating. The installation includes braided nylon coolant hoses with high-temperature sleeves, AN O-ring fittings for a leak-free connection, and all necessary mounting hardware, making it a reliable upgrade for your truck. Proper coolant flow is critical in the 6.7L Cummins, especially for the rear cylinders that tend to experience higher temperatures due to restricted flow. This issue can lead to catastrophic damage, including blown freeze plugs and costly repairs. The Fleece Performance coolant bypass addresses these concerns by providing a dedicated flow path that maintains optimal temperatures, thereby enhancing engine durability and performance. This kit is compliant with EPA standards and is an essential addition for owners seeking to maximize their truck's reliability and prevent potential cooling system failures. Whether you're restoring or upgrading your vehicle, this kit offers a straightforward, high-quality solution to ensure your Cummins engine runs cooler and more efficiently under demanding conditions.
