If you're looking to keep your engine running cool and strong, you might want to check out the CSF Engine Coolant Radiator. It’s not just another radiator; it’s designed with OE-style precision, which means it fits right in and gets the job done without any fuss. Trust me, keeping your cooling system in top shape is crucial if you want your vehicle to last. I’ve seen too many engines suffer from overheating simply because someone neglected this part.

Now, let’s get into the nitty-gritty. This radiator is a crossflow type with a single row, which is perfect for efficient cooling. The core measures in at 17 5/16" long, 17 1/4" wide, and 1 1/4" thick, crafted from lightweight yet durable aluminum. The tanks are made from high-quality plastic, designed to take a beating without cracking. It’s got the inlet located on the upper driver side and the outlet on the lower passenger side, with diameters of 1 5/8" and 1 9/16" respectively. That’s some solid engineering right there.

What really sets this radiator apart is its construction. The OEM specified plastic tank-aluminum core combo is a game-changer. The tanks are made from virgin grade engineered plastic resins that are glass-filled for extra strength. Plus, the gaskets are crafted from special grade EPDM rubber, so they can handle extreme temps—up to -120°F. And let’s not forget about the fins; they feature a high-performance multi-louvered design that maximizes cooling efficiency.

Before leaving the factory, every radiator is leak tested at 150% of operating pressure. That’s confidence you can count on. And if you’re worried about shipping, CSF’s packaging is top-notch, passing a rigorous 10-foot drop test. They really thought of everything, even ensuring that all components are installed, torqued, and tested during assembly.

CSF has been in the game for over 50 years, and they’ve sold more than 30 million units worldwide. They offer a wide variety of radiator models that cover over 3,200 applications—from Acura to Volkswagen. Whether your ride has a copper-brass, plastic-copper-brass, or all-aluminum radiator, CSF has got you covered. They’re all about quality, using the best materials and innovative designs that are wind tunnel tested for performance validation.

Now, if you’re driving a BMW 3-Series from 1991 to 1999 or a Z3 from 1996 to 1998, this radiator is a perfect fit. Just a quick tip: when you’re swapping out your radiator, don’t forget to check the old radiator pressure cap for any signs of wear. It’s the little things that can make a big difference.

In short, if you’re serious about keeping your engine cool, the CSF radiator is a solid choice. It’s built to last and designed for performance, so you can hit the road with confidence.
