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.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLowers coolant temperature at the rear cylinders\u003c\/li\u003e\n\u003cli\u003eEnsures consistent temperatures across all cylinders\u003c\/li\u003e\n\u003cli\u003ePrevents damaging coolant pressure build up\u003c\/li\u003e\n\u003cli\u003eComplete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eWhy do I need a Fleece Performance Coolant Bypass?\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eOne 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 Performance Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKit Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRear coolant bypass thermostat housing\u003c\/li\u003e\n\u003cli\u003eFront coolant bypass thermostat housing\u003c\/li\u003e\n\u003cli\u003eNew EGR cross-over tube gaskets\u003c\/li\u003e\n\u003cli\u003eBlack braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"fleeceperformance.com\/media\/wysiwyg\/FPE-2022-84-FPE-CLNTBYPS-CUMMINS-0712_1318.pdf\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/p\u003e","brand":"Fleece Performance","offers":[{"title":"Default Title","offer_id":46886012059897,"sku":"FPEFPE-CLNTBYPS-CUMMINS-1318","price":379.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5428\/0953\/files\/1e6788356d7a2cce9e1dcdebbd67de8c.png?v=1758754794","url":"https:\/\/octanehaus.com\/products\/fleece-performance-13-18-ram-2500-3500-6-7l-cummins-coolant-bypass-kit","provider":"Octane Haus","version":"1.0","type":"link"}
