For 2003-2007 Dodge Ram 5.9L 2007.5-2018 Cummins 6.7L Freeze Coolant Bypass Kit

Freeze Coolant Bypass Kit for Dodge Ram Cummins

This freeze coolant bypass kit reroutes coolant away from the factory EGR cooler on 2003-2007 Dodge Ram 5.9L and 2007.5-2018 Cummins 6.7L diesel engines, helping reduce coolant temperatures and protect the cooler from rupture.

Overview

This freeze coolant bypass kit is designed for 2003-2007 Dodge Ram 5.9L and 2007.5-2018 Cummins 6.7L diesel trucks. The freeze coolant bypass kit redirects coolant flow around the EGR cooler to help lower coolant temperatures under load. It is intended for diesel owners who want added protection against coolant overheating and cooler failure.

Specs At A Glance

Good To Know

Q: What does a freeze coolant bypass kit do? A: It reroutes coolant so it bypasses the EGR cooler, which helps lower coolant temperatures and reduce stress on the cooler. This can help prevent cooler rupture in the listed diesel applications.

Q: Does this kit require tuning or other modifications? A: Installation typically involves plumbing changes to the coolant circuit, and some setups may require supporting modifications depending on the truck. Confirm compatibility with your specific 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.
