E34 condenser fan.

Filed under: Uncategorized — admin @ 2:36 am

525i, ’94 wide grille model.
The a/c works. The condenser fan doesn’t. It appears to have siezed.
I turned it, using a screwdriver through the grill, but it’s still quite
stiff, so is probably burnt out, and will need replacing.
Anyone know if the fan be removed and replaced by simply removing the
radiator grille and panel?
TIA.
Mike.

    Hi Mike,

    You need to remove the front bumper to get at the mounting screws at the
    bottom and to disconnect the power connector to the fan. I had an 1996 E34
    518i and this is what I had to do to replace it. The fan comes out from the
    bottom. I don’t believe you can get it out from the top. If anyone knows
    better, then please correct me. Taking the bumper off is not a big job,
    about 10 minutes if that.

    Regards,
    Hamid

  2. You can remove it from the top. Remove the fan and shroud, unbolt the
    radiator, push it toward the engine unscrew the aux fan and you can work it
    out. It is a tedious procedure. Be carefule not to damage the rad or
    condensor.

    Easier to remove the bumper, surely? You can then also clean out all the
    crap that probably cause the fan to fail…

    Removing the bumper sounds the easiest way as long as the bolts, screws etc
    are not too rusted. If they are, the top method offers an alternative, so
    thanks for both suggestions.
    Maybe a non std fan will be replacing it, after seeing that the OEM one
    appears to cost around £100 !!. :-)
    Mike.

    137gbp according to my new Eurocarparts cat which arrived yesterday.
    Dunno if it’s possible to open them up and fix them – it’ll probably just
    be the armature that’s burnt out.

    They can always be opened up.
    Reassembly might need a bit more ingenuity. :-)

    Whilst it is possible to get small motors rewound, IME it’s usually not
    economical. Even less so if the commutator and brushes are also worn.
    Commutators  can be skimmed, but finding new brushes to fit can be a pain.
    If it’s a simple fix OK. Otherwise there appears to be ample space to fit a
    non std fan assembly. 12 volt fans are common enough on modern cars.
    I’m not far from GW Bridges near Crawley. I’m sure a browse round his yard
    will turn up a fan I can fit. Maybe even a good used BMW one, though it does
    seem a fairly common failure especially on older BM’s.
    From what I gather the OEM one has three speeds, presumably by using a
    temperature sensor to control the supply voltage. Those also appear to fail,
    giving one speed only. All getting a bit complicated for me.
    One speed should be enough to keep the a/c air cool whilst stationary or
    crawling along in traffic.
    Mike.
