Fits Year Make Model Engine 2019-2022 Dodge Ram 2500/3500 24V 6.7L Cummins The rear cylinders on the 6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure.

Technical Specifications:

• Fleece Performance coolant bypass kit adds a secondary thermostat, that, unlike other brands, works based on temperature instead of excessive pressure.
• This solves the problem before the pressure becomes an issue by ensuring consistent temperatures across all six cylinders.
• One of the biggest issues with the 6.7L Cummins is the coolant flow problem to the rear cylinders.
• This can cause catastrophic failure or blowouts of the freeze plugs in an over-temperature / over-pressure condition.
• The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.
