PART NUMBER: 61-3645
Protect your investment and increase not only performance, but also reliability with an upgraded aluminum high-performance radiator from CSF.
Fits 2002-2006 Mini Cooper S Hatchback (R53) and 2005-2008 Mini Cooper S Convertible (R52). Manual transmission only. Does not fit the non-supercharged Cooper as the inlet and outlet angles are different on those cars.
CSF gorgeous 2 row cores with B-tube technology, total core thickness is 31mm!

"B-Tube" technology - Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in a shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded.
The design (inlet in the middle of tube that is seam brazed) increases the heat transfer surface area of the tube by approximately 15% over regular tubes. You get the efficiency of 2 smaller tubes vs. 1 large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow."
The tubes are made from aircraft grade special clad aluminum and are intricately formed on our high precision 6-stage tube forming mill. No other aftermarket radiator manufacturer uses this technology. This technology raises the bar and sets the standard for high performance radiator cores.
Automatic Transmission: This radiator physically fits both manual and automatic cars, but it does NOT have a transmission cooler built into it for the auto transmission (factory automatic radiators have a transmission cooler integrated in to the radiator). This means you will need to install your own separate transmission cooler to attach the lines that come from the transmission to.
