Looks great, I need to do this badly. Maybe I will swing by the junkyard tomorrow and try to get something rolling. Eric you game for helping me wire it?

Yeah, I'm game, I think one good arm and one bum arm can do it

What about just wiring it to a in cabin on/off switch? How hard would it be to just flip the switch when you see the temp hit halfway? I'd *much* prefer this so I have total control. Besides, it would give me something to do.

You only need to forget once to have a really bad day. I can switch on my cooling fan manually by hitting the AC button. I usually end up switching on the AC before the engine needs the extra air flow of the fan. But once in a while the temp switch kicks in the fan without me noticing.

^Good point.
I check my temp guage constantly though, impossible for me to forget as my peripheral vision would catch the temp rise. Living in Hawaii, where it's 85 everyday I tend to pay attention to the guage more than most.

an a side note... an alternator from an E36 will fit and gives out 105A. ( don't remember year though)

I changed to the 80/88C temp switch, added two bottles of water wetter, and just yanked the whole clutch fan. I'm running only the stock aux fan. It kicks on when the temp gets a tad above 1/2. Even in stop and go with the A/C on full, it has never been up to 3/4 on the temp gauge.

I'm tempted to do the water wetter too. I did that on my e34m20 and it's worked like a charm. The temperature on the m42 isn't stable like the m20 though, maybe a leak or two that I have to cure before I go all fan delete-delete.

Were you having an issue with the temperature switch or did you replace it with the 318ti one? Mine turns on somewhere between 1/2-3/4 but it seems to work just fine. like that.

Nope nothing was ever wrong with that switch... I just never let it get high enough to have it switch on by itself. It switches on just before the 3/4 mark which seems fine to me. And we have 100 degree days almost every day now.

^Yup. I always wanted to do this, but the wiring always scared me..

I wired up mine differently than Wizard and it was not scary.

I have to go to New York for a few days, but will do a write-up when I get back...Wiring is fairly straight forward though..

Hey, thanks for this! I'm still confused about using the volvo relay.(sorry, I am very bad with wiring)

DLag30 · « **Reply #28 on:** June 26, 2009, 09:20:51 PM »

btw, can I use a aftermarket pusher fan instead(summit)?

tjts1 · « **Reply #29 on:** June 26, 2009, 11:53:25 PM »

You can but you already have a pusher fan in the car.
