This kit features a secondary thermostat that operates based on temperature rather than pressure, ensuring consistent coolant temperatures for all cylinders. It effectively lowers coolant temperatures at the rear cylinders, preventing excessive pressure buildup that can lead to freeze plug blowouts or failures. Constructed with braided hoses and AN O-ring fittings, the kit guarantees a leak-free installation, while MY 2003+ versions include billet hose brackets for added durability. This upgrade is essential for enhancing engine reliability and longevity, especially under demanding conditions.\u003c\/p\u003e\n\u003cp\u003eDesigned for 2003-2007 Dodge Ram trucks equipped with the 5.9L Cummins engine and automatic transmissions, this coolant bypass kit addresses common coolant flow issues in the rear cylinders.

The kit is suitable for street use, towing, and high-mileage driving, providing a reliable solution to prevent overheating and potential engine damage. It includes all necessary components for installation and is compatible with vehicles that experience coolant flow and temperature management challenges.\u003c\/p\u003e","brand":"Fleece Performance","offers":[{"title":"Default Title","offer_id":52562630312223,"sku":"FPE-CLNTBYPS-CUMMINS-0305","price":379.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0229\/3877\/files\/d13239d9eee4201063d3ca84fcc52294.jpg?v=1779509973","url":"https:\/\/shop.wheelflip.com\/products\/fleece-performance-03-07-dodge-5-9l-cummins-coolant-bypass-kit-03-05-auto-trans","provider":"WheelFlip","version":"1.0","type":"link"}
