Default Alternative cooling fan/motor for V6?

I have a non working fan motor, I suspect, on a V6.
Have anyone got experience with changing the motor and fan from another popular car, like BMW, VW (or anything else).
If so I would be interested in knowing more about it.
I am trying to replace the whole fan with an alternative good unit from any popular car. I would be interested in a wiring diagram as well.
(I have earlier replaced brushes, but the motor has now given up, maybe it has stopped working, I will find out in due course.)

Why? That is the most complicated and troublesome solution possible.

Ah, that's probably because you didn't buy the brushes from Engineering Carbon Products Ltd. in Croydon, England. Am I right or wrong Kaiser?

Kaiser - also curious as to alternatives as I don't like the press fit ones now supplied as genuine as my blades parted company, and sooner or later commutator wear will be terminal.

These seem very similar to ours, Siemens too, but whenever I try to find them over this side of the pond even with the same number the likeness ends. Perhaps the BMWs in Yankland had different fans fitted. Might be a chance that BMWs down your way have the Siemens type.

Thumbs up

Workaholic ro has used a Ford Mondeo fan and he posted a thread on how he did it. Ceedy posted on the same thread of using a fan from an alternative vehicle too. Thread is here: Click

How about one of these?

Has plenty of power and is only a little smaller than the original so that could be made up with some foam if it was needed.

Being VW it should be available world wide and be reliable, there is also plenty of copies of this fan available if you wanted to go that route, I suspect the mounting would need fiddling but nothing a few washers could not fix.

I was going to try one of these but have never got round to it, I am going to make it one of my winter projects I will let you know how it goe's or you could be the first to try it something along this line, more investigation required yet though as to which would be the best one to replace with.

Artic, I would be careful of using that fan, it is a puller not a pusher and as it has no makers name so will be of unknown quality ( probably Chinese). It does not even quote its Watts or CFM.

As far as controlling the fan there are various ways of controlling it, a probe in the bottom hose with a pre set temp or even a pulse width modulator controller like this http://autocooling.co.uk/

Buying a used fan from a scrapyard what ever vehicle it is from you need to careful. With most cars having A/C the cooling fan gets a lot of use and if you look how many aftermarket fans are available there has to be a demand.

OK the fan is out, the brushes are gone. It looks as if the middle section has worn through the copper on the commutator and has caused arcing between the brushes and the steel? under the copper coating.

I have found a motor that is virtually dimensionally identical. However it only has two permanent magnets and three wires in. It is off the BMW E36 for the air conditioning. It uses the same fixing of the fan itself.
Also from Siemens in Canada.

I now have to find out how to connect it to the existing wiring system.

Unlucky I guess, I've opened about eight fans and only one was worn exposing the bakelite (?).

BMW seem to be a minefield of different fans, I find one with the right three legged blade mounting and then the rear has four mounts unlike our three. Have you got a part no. for your near identical?
