E39 M5 and E52 Z8 Discussion
Since the only DIY on your radiator is for a 530, I'm going to do a writeup for my M5. I'm in the process of pulling the radiator now. I made a few mistakes along the way (and will eventually post pictures.)
Tools needed:
1-1/4" wrench (or metric equivalent) for pulling the fan.
Dual-hole fan...
