If you’ve dealt with cracked plastic tanks, leaking seams, or radiators that struggle to keep temps under control while towing or driving hard, you’re not alone. The Fluidyne 5 Row Extruded Tube Aluminum Radiator for the Chevy/GMC 2500HD and 3500HD 6.6L Duramax was built to solve those common problems with a stronger and more durable design made for real diesel use. Whether your truck is a daily driver, tow rig, work truck, or performance build, this radiator is designed to help maintain lower temperatures and dependable cooling under heavy load.

Unlike traditional aftermarket aluminum radiators that use thin, folded and brazed tubes, Fluidyne uses a single-piece extruded aluminum core design that removes one of the most common failure points found in standard radiators. The result is improved durability, better heat transfer, and added confidence when towing, hauling, or pushing your truck harder than stock. Backed by more than 30 years of racing and cooling experience, including use in NASCAR applications, this crossflow radiator features a dense 5-row aluminum core, proprietary fin design for improved airflow, thick aluminum tanks, and an integrated transmission cooler. It’s designed as a direct-fit replacement for Chevy/GMC 2500HD and 3500HD Duramax trucks and ships in heavy-duty protective packaging to help ensure it arrives ready to install.

This radiator features a natural aluminum finish, 34-inch core length, 23.5-inch core height, 2-inch core depth, upper driver-side inlet, lower passenger-side outlet, and built-in transmission cooler. Overall dimensions measure 44.8 inches long, 24.7 inches high, and 5.57 inches deep. Please note, fan and radiator cap are not included.
