If you're looking to keep your ride cool under pressure, let me tell you about the CSF radiator. These guys have been in the game for over 50 years, and they’ve sold more than 30 million units worldwide. That’s not just a number; it’s a testament to the quality and reliability you can expect from their products.

CSF has a massive lineup, covering more than 3,200 applications. Whether you’re rolling with an Acura or a Volkswagen, they’ve got a radiator that fits your needs. And it doesn’t matter what type you have—Copper-Brass, Plastic-Copper-Brass, Plastic-Aluminum, or All Aluminum—CSF has you covered. They use the same materials and construction style as the original equipment (OE), so you know you’re getting something that performs.

What really sets CSF apart is the attention to detail in their engineering. Each radiator is built to high performance standards and is wind tunnel tested to validate cooling performance. The tanks are made from virgin-grade engineered plastic resins, which are glass-filled for that extra strength and durability. Plus, they use special EPDM rubber for the gaskets, ensuring they can handle extreme temperatures—down to -120°F. That’s some serious resilience!

And let’s talk about the core design. The high-performance multi-louvered fins are what really get the job done, maximizing cooling efficiency. Before these radiators leave the factory, they go through a rigorous leak test at 150% of the operating pressure. Talk about peace of mind! They even package these bad boys to withstand a 10-foot drop, so you know they’ll arrive in one piece.

Now, if you’re curious about the specs, here’s the rundown: it’s a crossflow radiator with a single row. The core measures 34 inches long, 22.75 inches wide, and 7/8 inch thick, made of aluminum. The inlet is located on the upper driver side, and the outlet is on the lower passenger side, with diameters of 1.25 inches and 1.5625 inches, respectively. Plus, it comes with a high-efficiency plate-type oil cooler.

As for fitment, this radiator is perfect for the Chevrolet Silverado 2500 and 3500 from 2011 to 2019, as well as the GMC Sierra 2500 and 3500 for the same years. Just a heads up—when you swap out your radiator, take a minute to check the old pressure cap for wear and tear. It’s those little things that can make a big difference in your cooling system’s performance.

Take care of your radiator, as under circumstances listed below the warranty will be void.

If the radiator is installed and is returned deformed (bulging tanks, warped core etc.), this is an indication that the radiator is the victim of some other problem and not the cause. The deformation is a result of the radiator being subjected to extremely high pressure and or temperature caused by any of the following reasons:Defective Pressure Cap, Defective Head Gasket, Defective Temperature gauge (incorrect readings), Defective Water Pump etc. Such units are not covered under the warranty.

If a radiator seems to have a “fit problem” there is the possibility that there is some confusion about a multi-fit radiator that might look different. Your nearest CSF WD can clarify the application, just give them a call. A perceived fit problem is not covered under warranty.

If a unit is damaged in shipping, please file a claim with the carrier. Damages caused during shipping, installation or handling are not covered under warranty.
