Good To Know

Q: What does a freeze coolant bypass kit do? A: It reroutes engine coolant so the intake manifold is not heated by the cooling system. That helps keep intake air cooler on turbo diesel engines.

Q: Will this fit both the 5.9L and 6.7L Cummins engines? A: This kit is listed for the 2003-2007 Dodge Ram 5.9L and the 2007.5-2018 Cummins 6.7L. Confirm your model year and engine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
