Sinister Diesel 03-18 Dodge RAM Cummins 5.9L Radiator Pipe

This radiator pipe from Sinister Diesel is made from durable, mandrel-bent aluminum tubing. It's designed to replace the stock rubber hose that connects your radiator to the coolant reservoir on 2003-2018 Dodge RAM trucks with the 5.9L Cummins engine. Upgrading to a solid aluminum pipe helps prevent the common issue of the factory rubber hose collapsing under vacuum, which can restrict coolant flow and lead to overheating.

The mandrel-bent construction ensures smooth, consistent bends without any kinks or flat spots, allowing for optimal coolant flow. This means your engine's cooling system can operate more efficiently, especially under demanding conditions. The aluminum construction is also resistant to the heat and chemicals found in the engine bay, offering a long-lasting solution compared to the original rubber hose.

This pipe is a direct replacement for the factory part, meaning it fits right into place without needing modifications. It's a solid option for anyone looking to improve the reliability of their Cummins cooling system.
