CSF has developed the ultimate performance cooling radiator for the BMW E39 with trusted R&D partners and BMW specialists. The CSF Dual-Pass Race-Spec Oil Cooler can be paired with this radiator but requires custom work to connect to the E39 M5’s oil lines.

Even though our E39 M5 has been well maintained and is in excellent shape, it is still a 20-year-old car and some components were starting to show their age. In our car the radiator, as is common with most modern cars, started to develop some weeping where the plastic end tanks are crimped to the aluminum radiator core. Nearly all newer cars have this type of radiator construction and most will start to leak like this at 10-20 years of age as the seal between the tanks and the core starts to deteriorate. We decided to intervene before our seeping turned into a major leak and replaced the OEM radiator with a high-quality racing radiator from CSF Race..
