    Default Electric cooling fan, yes or no?

    I think my fan clutch might be going. My temp tends to rise a tad at idle, even towards the 3/4 mark this afternoon, I turned on the heating. I've been thinking about installing an electric fan, the one bmwe34.net suggests. Is anyone on here running an electric fan, if so, would you recommend one? How about an adjustable Tstat to go with it? (is it even necessary?)?

    You can't go wrong fitting an electric fan! I haven't got one on my M20'd engine but cars I've owned in the past have had them and they work great. Just make sure the fan's thermostat is reliable - a known weak spot in aftermarket kits.

    Cheers,

    Revision, just tried spinning my radiator fan by hand, offered lots of resistance, no free spinning whatsoever so I guess the clutch is fine. Still though, for the guys who have replaced their clutched radiator fans with electric ones, would like to hear from ya.

    Lenny, sounds like your electric fan isnt working. Check it by turning the AC on and see if the fans running in front.

    The aux fan works, but only when I turn the A/C on. I just replaced the resistor, which had blown. I'll replace the aux fan switch tonight. Still though, the temp shouldn't be climbing even without a working aux fan, I would think.

    when my fan clutch goes i'm going to do the conversion and then i'll get back to you guys. considering the clutch is about $90+ and so is an electric fan i figured why not ? i looked up the brand bruno mentioned on his site and other people had given it positive reviews as well so i'm not too worried about it dying unexpectedly.

    your right Lenny, shouldnt overheat without the aux fan. Maybe your radiator is partially clogged or something.
