Description

The Fleece Performance Coolant Bypass for the 2013-2018 RAM with 6.7L Cummins seamlessly integrates with your truck for an OE fit-and-finish. It increases coolant flow and decreases coolant temperatures, preventing damaging coolant pressure buildup and ensuring consistent temperatures across all six cylinders. The kit includes front and rear coolant bypass thermostat housings, new EGR cross-over tube gaskets, braided hose with AN O-ring fittings, and mounting hardware. For some applications, an additional heater tube may be required.
