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\u003col\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.

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\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e2003-2005 \u003cspan\u003eDodge Ram 2500\/3500 5.9L 24V Cummins\u003c\/span\u003e w\/ Auto Trans\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplication Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe 2003 - 2007 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger.
