Upgrade your Chevy/GMC 2500HD or 3500HD 6.6L Duramax with the Fluidyne 5 Row Extruded Tube Aluminum Radiator. Built for diesel trucks that tow, work, and run under heavy heat, this radiator is designed to deliver stronger cooling performance and long-term durability compared to standard aftermarket radiators.
Fluidyne’s extruded aluminum core uses a strong single-piece tube design that helps eliminate common failure points found in folded and brazed radiator tubes. With race-proven cooling technology, thick aluminum construction, and a proprietary fin design for improved heat dissipation, this radiator is built to handle real diesel stress from daily driving to heavy towing and performance use.
Designed as a direct-fit crossflow radiator for Chevy/GMC 2500HD and 3500HD models with the 6.6L Duramax, this aluminum radiator includes an integrated transmission cooler and ships in heavy-duty protective packaging to help ensure it arrives ready to install.
