Maybe you’re still the first owner. Maybe you’re the sixth. That old 24 Valve still wants to work. You could replace your tired worn out radiator with an equivalent from the local parts house- or find a “performance” one online. But they both have the same thing in common: the way they’re made. When you form a tube from a flat piece of aluminum, it’s bound to leak. That’s why we borrowed a page from our NASCAR designs- using tube extrusion. Seamless tubes are formed for all of our diesel radiators- so you get leak free performance year after year.

You bought a Cummins because you expect it to work. The radiator should be able to keep up.

FLUIDYNE Performance extruded tube radiators for the 2013–2018 Cummins are built for the towing, hauling, added power, summer heat, and everyday miles these trucks see.

Better construction, more cooling, and one less thing holding your truck back when you ask it to do what you bought it for.

If your 4th Gen Cummins is on its second replacement- or you just want to find a reliable upgrade- the search stops here. Compared to stock AND the competition- we are the only aftermarket supplier of extruded tube radiators- which is fancy speak for “IT WONT LEAK”.
While others use the cost effective way to make theirs, we invested into making sure you don’t have to call us for a warranty.
The choice is simple - keep replacing with the same thing over and over, or make this one the last radiator you’ll need.

If you’re done filing warranty claims with other brands, maybe it’s time to make a change. The difference from us and all the others is our extruded tube design- which means you’ll never have a leak. You shouldn’t have to swap out a radiator once or twice a year- move to Fluidyne and forget it.

When you look at the factory transmission cooler, you’ll think “That’s not professional Grade. The bean counters will skimp where they can. And your transmission isn’t a place you want to concede. Give it the cooling it deserves- with our extreme heavy duty bar plate cooler. More fins, more dissipation, and more capacity over stock.

Doesn’t seem like a hard concept. We could have made the accountants happy with less material, and making tubes out of thin laser welded flat plate.. or we could fire the bean counters and do our own thing.
We chose the latter. If you’re on your second or third warranty replacement “performance” radiator, you’re using the wrong one. Make the switch and see the Fluidyne difference.

You bought the radiator to keep your diesel cool- but did you think about the transmission? Each time your transmission shifts or the torque converter unlocks, it generates more heat. And just like your engine, keeping a cool transmission will help keep it alive. That’s why we have invested into bringing the stoutest and biggest transmission coolers to market- that STILL fit in the OEM position. Plus with its added capacity- it ensures you’ll have more cool atf on tap. Ready to upgrade? Check out the entire lineup of true performance transmission coolers - at Fluidyne.com

There’s a reason we don’t have to sell the warranty first.

If you’re comparing radiators, compare the engineering. Fluidyne’s extruded tube design wasn’t built to win a marketing contest. It was built to keep your truck cool and LEAK FREE when it actually matters.

Some radiators are built to cool. Others are built to keep a warranty department busy. Our extruded tube radiators for the 2011-2016 6.7L Powerstroke were built to stay in your truck, not come back out.
