If you're looking to keep your engine cool without breaking the bank, the CSF radiator is a solid choice. I've had my fair share of experiences with various radiators, and I can say that CSF really knows their stuff. They’ve been in the game for over 50 years, and with more than 30 million units sold, you can trust they’ve got the quality down to a science.
What I love about CSF is the variety—they’ve got over 3,200 applications covered, so whether you’re driving an Acura or a Volkswagen, chances are they’ve got a radiator that fits. This particular model is designed with a crossflow layout, which means it’s engineered for optimal cooling efficiency. It’s got a single row core that measures 22 13/16” long, 17 5/8” wide, and 1 1/4” thick, making it a compact yet powerful option for your ride.
One of the standout features here is the OEM specified Plastic Tank-Aluminum Core construction. The tanks are crafted from virgin grade engineered plastic resins, and they’re glass-filled for added strength and durability. This means you won’t have to worry about them cracking under pressure. Plus, the gaskets are made from special grade EPDM rubber, which can handle extreme temperatures—up to -120°F. That’s some serious resilience!
When it comes to performance, CSF doesn’t skimp. They’ve got a high-performance multi-louvered design in the fins, which really helps with airflow and cooling. And before these radiators leave the factory, they undergo rigorous testing—each one is leak tested at 150% of the operating pressure. That’s peace of mind right there.
Installation is straightforward, with the inlet located on the upper driver side and the outlet on the lower passenger side, both with a diameter of 1 1/2”. Just a heads up, if you’re swapping out your radiator, make sure to check the old pressure cap for any wear. It’s a small detail that can save you headaches down the road.
This radiator fits the BMW 320i from 1999 to 2006 and the BMW Z4 from 2003 to 2008, making it a perfect fit for those models. If you’re in the market for a reliable, high-quality radiator that won’t let you down, give CSF a shot. You won’t regret it!
