850 electric fan in 240



  • I noticed this has been up for a few years now and wanted to see how peoples experiences have been. I'm doing this conversion this weekend with 850 fan and bmw 2 speed fan switches. I've got a couple to test:

    1. on 91 - off 86, on 99 off 94
    2. on 80 - off 75, on 88 of 83

    Any consensus on whether to use the top or bottom hose? and what temps/speeds to use?

  • Top hose.
