The Last Diesel Radiator You'll Ever Need
Fluidyne Extruded Aluminum Diesel Radiator For 2006 - 2010 GMC/Chevy 2500/3500 - Diesel & Gas
Sick of cracked, leaking aftermarket radiators? So are we. For decades, diesel truck owners have settled for radiators that simply can't take the heat. At Fluidyne, we're putting an end to that permanently.
Over 30 Years of Proven Performance
For more than three decades, Fluidyne has been a leader in high-performance cooling systems. Our products have powered championship-winning NASCAR teams, extreme off-road builds, and high-horsepower street machines. When it comes to cooling under pressure, nobody does it better.
Now, we're bringing that same elite-level technology to the diesel world. Our extruded aluminum diesel radiators are engineered from the ground up to outperform and outlast every traditional radiator on the market.
Built with NASCAR-Proven Technology
Our extruded tube core is a single-piece design not a patchwork of thin, brazed tubes like most aftermarket aluminum radiators. This solid-core construction eliminates the header joint, the #1 failure point in conventional designs. It's the same technology we use in our official NASCAR oil coolers and now it's available for your truck.

Thickest Tanks in the Game

Compatible with 2006 - 2010 GMC/Chevy 2500/3500 6.6 Duramax & 5.7/6.0/8.1 Gas
Upgrade the Whole System
