As for the fan dude, is there not a sticker that has all the manufacturer b*llocks on etc? If so does it not have a little arrow on it stating the direction? (i'm just going by the Spal fans we have in work for the busses

For the water wetter, i've read up a bit on the delete kit and from what some of the peeps have decided to do when refilling the coolant system is 50/50 mix of water and antifreeze +1 bottle of water wetter. Thats going from what i've read up on e36coupe.com
