Product Overview
The Sinister Diesel Radiator Pipe for the 2010–2018 Ram Cummins is designed to replace the weak factory coolant tube with a stronger, more reliable solution built for the demands of a turbo diesel engine.

Factory coolant tubing is known to become brittle and fail over time, especially in high-heat environments and tuned applications. This upgraded radiator pipe replaces those weak points with durable 6061 aluminum tubing and high-strength silicone boots designed to handle long-term heat and pressure without cracking or deterioration.

Precision mandrel bends ensure a proper fit while maintaining smooth coolant flow throughout the system. Combined with stainless steel clamps and 4-ply silicone boots, this setup delivers a secure, dependable seal built for daily driving, towing, and performance applications.

Finished in Sinister Blue powder coat, this pipe not only improves durability but adds a clean, finished appearance under the hood.

Installation is straightforward with a direct-fit design requiring no cutting or modifications.
