CSF’s exciting engine cooling offering for those seeking to swap BMW’s S54B32 into their E30/E36. A drop-in solution with provisions for an electric fan and an uprated oil cooler.

At first glance this radiator looks very similar to CSF’s E36 M3 Radiator (#3054). While the overall shape is very similar, there are several key features that make the new swap radiator special. Because the S54 requires a much more robust oil cooling system than the E36’s S52/S50 or E30’s S14, CSF made special provisions to fit two different race spec oil coolers. Please note, this radiator and oil cooler combination can be used for S50 swaps as well. To do this, the height of the radiator was reduced slightly so the CSF race spec coolers can fit it in a factory-style location. The radiator includes a custom designed oil cooler mounting bracket which has provisions to fit both CSF #8032 & #8240 oil coolers. In addition, a custom designed radiator cover plate allows for an optimized coolant overflow line placement which is concealed for an OEM+ appearance.

CSF also includes brackets for an electric fan conversion. These brackets are designed to fit a single 16″ SPAL fan (not included). While it is possible to retain a clutch-type fan, it is much easier to convert to an electric fan on top of the performance benefits.

The two-row 42mm aluminium core offers the largest coolant capacity possible and incredible heat dissipation. CSF’s exclusive B-Tube technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. All mounting brackets are CNC Machined for precise fitment. The cooling inlet/outlet connections use E36/E30 OEM style slip on connections.

This product includes fan brackets for use of 16 inch SPAL fan (SPAL #30100400 – not included), Oil Cooler Mounting Bracket for fitment of both the CSF #8240 (w/ A/C) & CSF #8032 (w/o A/C) and two top cover plates (black and satin) to cover the top of the radiator for a clean OEM+ look.
