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:
on 91 - off 86, on 99 off 94on 80 - off 75, on 88 of 83
Any consensus on whether to use the top or bottom hose? and what temps/speeds to use?
