If you're looking to keep your engine cool and running smoothly, you might want to check out the CSF radiator. I’ve been around the block with radiators, and let me tell you, CSF knows what they’re doing. They’ve got a massive lineup, covering over 3,200 applications, so whether you’re driving an Acura or a Volkswagen, they’ve got you covered.

What I really appreciate about CSF is their commitment to quality. They manufacture radiators that match the original equipment (OE) style and materials, so you know you’re getting something reliable. They’ve been in the game for over 50 years and have sold more than 30 million units worldwide. That’s a lot of trust from drivers who want performance and durability.

Now, let’s dive into some of the features that set these radiators apart. The construction is pretty impressive, with an OEM specified Plastic Tank-Aluminum Core setup. The tanks are made from virgin-grade engineered plastic resins, and they’re glass-filled for extra strength. You won’t have to worry about them cracking under pressure. Plus, the gaskets are crafted from special grade EPDM rubber, designed to handle extreme temperatures—up to a chilly -120°F. That’s some serious resilience!

The fins, which are the heart of the radiator, feature a high-performance multi-louvered design that maximizes cooling efficiency. And you can trust that every unit is 100% leak tested before it leaves the factory, operating at 150% of the standard pressure. They even go the extra mile with their packaging, passing a "10-foot drop test" to ensure it arrives at your door in perfect condition.

When it comes to specs, this radiator is a crossflow type with two rows. The core measures 33 7/16" in length, 27 7/16" in width, and 2 3/16" in thickness, all made of aluminum. The tanks are plastic, and you've got the inlet located on the upper driver side and the outlet on the lower passenger side. The inlet diameter is 2", while the outlet is 2 1/4". Plus, there's an 11 1/2" right oil cooler that’s a high-efficiency plate type, which is a nice touch for those who really push their vehicles.

As for fitment, this radiator works perfectly with the Chevrolet Silverado 2500 and 3500 models from 2017 to 2019, as well as the GMC Sierra 2500 and 3500 of the same years. Just a heads-up: when you’re swapping out your radiator, make sure to check the old radiator pressure cap for any signs of wear and tear. It’s one of those little things that can save you headaches down the line.

In short, if you want a radiator that’s built to last and perform, CSF is a solid choice. It’s not just about cooling; it’s about keeping your ride in tip-top shape.
