Another thanks to Chris for the original solution - brought the resistor online from "element14" here in HK - sprayed black with hi-temp paint to help heat dissipation
So I took my car for a hard drive up in the hills yesterday, and afterwards my car had the humming noise going after it was shut off. After reading threads I believe the power steering pump was still on, My battery has drained when I woke up today.
I'm unsure what needs to be fixed at this point - do I need to replace this resistor? Is my fan not working properly? My steering felt fine and the pump just kept running, so is the pump likely ok?
Also, the power steering fluid reservoir looked like it had leaked out the top, possibly from overheating.
Does anyone have any recommendations on what I should check out first? I have an early 06 mcs.
The radiator fan (which this thread is about) is a different thing that what you're experiencing. There is a small fan on the underside of your power steering pump, and that's a potential problem as well.
I'm not sure, but there's probably some relay somewhere that's staying on, causing your power steering pump to run on.
Hi / Changed my post now after re-reading entire thread think i have the correct assembly for my 02 cooper
Just to report im in the middle of rebuilding the midlands gearbox as bought the car for my wife... cheap with a shot transmission
anyways taking everything apart i found an almost brand new fan assembly cant be more than a year old and look at the coating on the resistor
cant see any breaks on the coil itself though and its not reading any ohms ?
Also i was not getting first stage cooling so i will have to investigate more
Just thought i would leave this picture up just to show how quickly these go.........not much point fitting dealer fans really unless you have deep pockets.
Thanks for this thread guys its a big help.

I mounted mine on the aluminum engine mount on the drivers side. bolted it with three screws tapped into the mount, and used heatsink paste for a better contact point. it makes the mount fairly warm, and the resistor gets far too hot to touch. been working for almost a year now!
Just finished my install following the information provided by Chris.
Ordered from Mosher and took two days to deliver.
I mounted mine in the same location as Chris.
Drilled 7/64 holes and used self tapping metal screws. My cordless drill make easy work of this.
I also used 12 guage wire and three way scotch connectors.
The one thing I did slightly different was I used crimp connectors for attaching the wires tp the Mosher unit. These had heat shrink material on them so the connection is not only tight but will keep junk out.
For what it's worth, I purchased my connectors, wire and "thermal paste" all at Radio Shack. So if you have one of those near by, they can help.
Now my fan works as advertised and no more cooling worries (for now)
Big thank you to Chris and eveyone else who contributed to this thread........helped educate me and solve my issue.
As an additional FYI, I searched NAPA Auto Parts online catalog and they list the replacement fan assembly for $114 and is noted as a Dorman product.
Hey All,
There is now a direct replacement for this unit, I'm stocking these now as is Chad at DT. its worth it. Its a few wires to swap over and bolts right in place.
