Designed to address a critical cooling system weakness, this kit improves coolant flow to the rear cylinders of the 6.7L Cummins engine, which are prone to overheating due to insufficient coolant circulation. By integrating a secondary thermostat that operates based on temperature rather than pressure, the kit ensures consistent coolant temperatures across all cylinders, preventing excessive pressure buildup and potential freeze plug failures.\u003c\/p\u003e\n\u003cp\u003eThis coolant bypass solution is essential for owners seeking to enhance the reliability and longevity of their Cummins-powered Ram trucks, especially under demanding driving conditions or heavy-duty use.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003eThe Fleece Performance Coolant Bypass Kit offers a range of benefits that directly improve engine cooling efficiency and durability:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncreases coolant flow to the rear cylinders of the 6.7L Cummins engine\u003c\/li\u003e\n  \u003cli\u003eReduces coolant temperatures, preventing hot spots and overheating\u003c\/li\u003e\n  \u003cli\u003eMaintains consistent coolant temperature across all six cylinders\u003c\/li\u003e\n  \u003cli\u003ePrevents damaging pressure buildup in the cooling system\u003c\/li\u003e\n  \u003cli\u003eFeatures a secondary thermostat that activates based on temperature, not pressure\u003c\/li\u003e\n  \u003cli\u003eIncludes braided nylon coolant hose with high-temperature protective sleeve\u003c\/li\u003e\n  \u003cli\u003eAN O-ring fittings ensure a secure, leak-free installation\u003c\/li\u003e\n  \u003cli\u003eOE-style fit and finish for seamless integration with factory components\u003c\/li\u003e\n  \u003cli\u003eHelps prevent freeze plug failures and costly engine damage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eConstruction \u0026amp; Design\u003c\/h3\u003e\n\u003cp\u003eFleece Performance designed this coolant bypass kit with durability and precision in mind.
