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. Kits for MY 2003+ include billet hose brackets. Why do I need a Fleece Coolant Bypass? One of the biggest issues on the 5.9\/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. The '03-'07 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is not a fluid cooler, it was designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed. All 07-13 6.7 trucks, both automatic and manual equipped transmissions, do not have a transmission fluid heat exchanger.\nRecommended Cross Sell Skus - FPE-HX35-63-FMW\n\u003cul\u003e\n  \u003cli\u003eComplete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation\u003c\/li\u003e\n  \u003cli\u003eEnsures consistent temperatures across all cylinders\u003c\/li\u003e\n  \u003cli\u003eLowers coolant temperature at the rear cylinders\u003c\/li\u003e\n  \u003cli\u003ePrevents damaging coolant pressure build up\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Fleece Performance coolant bypass kit is designed specifically for the 5.9L Cummins engines in Dodge Ram trucks from 1994 to 1998, providing a crucial upgrade to address coolant flow issues that affect rear cylinders. This kit enhances engine cooling efficiency by adding a secondary thermostat that operates based on temperature, ensuring uniform coolant temperature across all cylinders. Proper coolant flow reduces the risk of excessive pressure buildup, which can lead to blowouts of freeze plugs and costly engine damage. The comprehensive kit includes braided hoses and AN O-ring fittings for a secure, leak-free installation, with billet hose brackets included for MY 2003+ models, ensuring durability and ease of setup. Maintaining optimal coolant temperatures is vital for engine longevity, especially in high-demand or towing applications, and this bypass system helps prevent overheating at the rear cylinders while promoting consistent engine performance. The design also eliminates the factory transmission fluid heat exchanger in certain models, simplifying the cooling system and reducing potential failure points without compromising vehicle operation. This upgrade is essential for owners seeking improved reliability and extended engine life in their Dodge Cummins trucks. The kit's compatibility with a range of Dodge Ram models from 1994 to 1998 makes it a versatile solution for enhancing cooling performance across various configurations, ensuring your vehicle operates smoothly under demanding conditions. Whether you're restoring an older model or upgrading for increased durability, the Fleece Performance coolant bypass kit offers a practical, high-quality solution to common cooling challenges faced by Cummins owners.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAdds a secondary thermostat that operates based on temperature, not pressure\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsures consistent coolant temperatures across all cylinders\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLowers coolant temperature at the rear cylinders\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrevents damaging coolant pressure buildup\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes braided hoses and AN O-ring fittings for leak-free installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eKit for MY 2003+ models includes billet hose brackets\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for 5.9L Cummins engines in Dodge Ram trucks from 1994 to 1998\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEliminates factory transmission fluid heat exchanger in certain models for improved cooling efficiency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImproves engine reliability and longevity by addressing coolant flow issues\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n1994 Dodge Ram 2500 Base\u003cbr\u003e\n1994 Dodge Ram 3500 Base\u003cbr\u003e\n1995 Dodge Ram 2500 Base\u003cbr\u003e\n1995 Dodge Ram 3500 Base\u003cbr\u003e\n1996 Dodge Ram 2500 Base\u003cbr\u003e\n1996 Dodge Ram 3500 Base\u003cbr\u003e\n1997 Dodge Ram 2500 Base\u003cbr\u003e\n1997 Dodge Ram 3500 Base\u003cbr\u003e\n1998 Dodge Ram 2500 Base\u003cbr\u003e\n1998 Dodge Ram 3500 Base\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\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\u003eCarb Eo Number: D-834-9\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":53602490548497,"sku":"FPE-CLNTBYPS-CUMMINS-12V","price":379.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/3830\/0689\/files\/59a8768bd6210aa1c0a88d31474b3cb5.jpg?v=1779946812","url":"https:\/\/shoprenegade.com\/products\/fleece-performance-94-98-dodge-5-9l-cummins-12v-coolant-bypass-kit","provider":"Renegade Speed by Renegade Racing \u0026 Performance","version":"1.0","type":"link"}
