Review on CSF 3717 Radiator by Joe Bottomkent

My wife's 2013 BMW X1 (N20 2.0L Turbo) had a radiator leak. If you look around, there are many options. Some cost several hundred dollars. It was a direct replacement. There are slight differences in the aluminum core. But the size and connections are perfect. My original BMW part number is 17 11 7 547 059. The CSF part number is 3717. Might be a few bucks less elsewhere. But Revain sent in 3 days. Packed in a big box at the top of the factory. No damage at all. Excellent work.
