Fleece Performance Coolant Bypass Kit for 2019+ RAM 6.7L Cummins

Introducing the ultimate solution for 2019+ RAM owners with the 6.7L Cummins engine – the Fleece Performance Coolant Bypass Kit. This innovative kit is designed to enhance the cooling system of your RAM, ensuring optimal performance and longevity. With its patent-pending design, the kit seamlessly integrates with your vehicle, providing an OE fit-and-finish that you can trust.

Key Features and Benefits

The Fleece Performance Coolant Bypass Kit boasts several remarkable features that set it apart from other products on the market. One of its standout benefits is the increased coolant flow, which leads to decreased coolant temperatures. This is especially crucial for the rear cylinders of the 6.7L Cummins engine, which often suffer from a lack of coolant flow and subsequently experience higher temperatures. The kit includes a secondary thermostat that operates based on temperature rather than pressure, effectively preventing coolant pressure buildup and ensuring consistent temperatures across all six cylinders. The benefits are clear:
  • Lowers coolant temperature at the rear cylinders
  • Ensures consistent temperatures across all cylinders
  • Prevents damaging coolant pressure build up
  • Comes with braided hose and AN O-ring fittings for a leak-free installation

Why Choose the Fleece Coolant Bypass Kit?

The 6.7L Cummins engine has a well-known coolant flow issue, which can lead to catastrophic failure or blowouts of freeze plugs in an over-temperature/over-pressure situation. The Fleece Coolant Bypass Kit is the perfect solution to address this problem, improving the reliability and longevity of your Cummins engine. By adding this kit to your RAM, you'll enjoy enhanced performance and peace of mind on the road. The kit is a must-have for anyone looking to protect their investment and ensure their engine operates at peak efficiency. With its comprehensive features and easy installation, the Fleece Coolant Bypass Kit is a smart choice for RAM owners seeking top-notch cooling system performance.
