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.

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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eIncludes braided nylon coolant hoses with protective high-temperature sleeves and AN fittings for leak-free installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdds a secondary thermostat to regulate coolant temperature based on real-time conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsures consistent coolant temperatures across all cylinders, especially the rear ones\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eReduces coolant temperature at the rear cylinders to prevent overheating\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrevents damaging coolant pressure buildup that can lead to freeze plug blowouts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eComplete kit with all necessary mounting hardware and gaskets for an easy upgrade\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for 2007.5-2012 Dodge Ram 6.7L Cummins engines\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImproves engine reliability and longevity by optimizing coolant flow\u003c\/li\u003e\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Eo Number: D-834-7\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: Compliant\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Fleece Performance","offers":[{"title":"Default Title","offer_id":53602323202321,"sku":"FPE-CLNTBYPS-CUMMINS-0712","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/3830\/0689\/files\/1ae7c7853f9f3b354668b0199ebe5632.png?v=1779936271","url":"https:\/\/shoprenegade.com\/products\/fleece-performance-coolant-bypass-kit-for-2007-5-2012-dodge-ram-6-7l-cummins","provider":"Renegade Speed by Renegade Racing \u0026 Performance","version":"1.0","type":"link"}
