Retrofit PS Fan to Mini Cooper

Hello,

I'm in the South of France and we have a Mini Cooper (not S) and we're having some issues with the PS pump not working when it's warm outside, which is a lot at the moment.

I figured this was probably because the fan wasn't working but in fact there is no fan fitted to the car at all (I believe it may have been a German car when new).

Does anyone know if you can retro-fit a fan? I can't see any additional or spare wiring near the pump so I'm wondering if it's possible?

Thanks for your help in advance!

Chris

PS pump fan only fitted to S here in UK due to extra underbonnet heat generated by supercharger. I guess the same for German export MINI's as it is similar northern europe climate. I believe some hotter export climates also have the fan fitted to the Cooper and One models but I doubt the wiring is fitted to all versions.

Hi ya

As above +1 if you are starting to have a problem you need to find the fault

I would also look at the wiring to start with. I would personally start by look at you engine to body earths do a resistance check on them and I would also check your engine bay fuse box this can be a problem area.
Then run a diagnostic on the power steering pump. This can be done using the bmw dis software. (eBay)

You may find the pump is on its way out, these pump scan cause some really funny faults.

How old us your battery ?

Hope this helps

Thanks for the replies. The connections all looked okay and not sure on the battery. Could be old but the problem is very heat dependant so I guess the thing is either cutting out on purpose because it thinks it's too hot or something is getting too hot, causing to cut out.

Either way I'm hoping to take it out at the weekend dismantle it and clean it up, as per the guides. I do have DIS and INPA etc so will check that out too.

Was just hoping to be able to add the fan to help it going forward. Guess it wouldn't be too hard to hook one up and have it controlled off the A/C fan if necessary.

Chris, if the pumps got faults ( there are only 4 fault codes it holds in memory) then your pumps on the way out, cleaning the motor (brushes) may add some life but if the electronic control circuits are damaged then its just a matter of time, The cooling fan if you fit one to the original wiring is independent of the power steering pump and controlled by the engine temp and dependant on the wiring will turn on with either the low circuit or high circuit when the engine reaches a pre determined temp.

The power steering pump reduces to 80% efficiency at a set temp, if the threshold reaches 100% then the pump shuts down to protect its electronic controller.

If you choose to replace the pump with a ZF OEM pump, they are supposed to be better than the original factory units, not sure what their cost is in the EU but here in Australia they retail from AU$750.00 to AU$1100 which I find a bit annoying considering they are manufactured in Kulim, Malaysia since the start of 2014 as ZF has set up the main manf plant there for power steering pumps and steering racks etc.

Quick Update on this as I've managed to spend some time on it over the weekend. Some notes

* took off the pump, dismantled and cleaned, re-assembled, no change, still working intermittently
* It already has been changed at some point with a reman one
* little tabs to the brushes and already been cut and were re-soldered
* The circuit board was pretty clean and the two main power transistors had been changed
* Some of the other chips have signs of heat - see pics
* Checked earth resistance and voltages on the supplies and it all seems good
* cleaned terminals

Interrogated with INPA:
* Had a couple of faults in INPA including an overheating one
* When it's not working, the control unit can be identified but it's error memory / live data can not be read
* when it is working, all the live data and memory works fine

Seems to be no rhyme or reason on when it does and doesn't work. Can toggle the ignition a dozen times and it won't work once, or it'll work a couple of times in a row.

Seems to be the control unit has just packed up. I'm going to contact the previous owner to see if he has a receipt for the replacement box.

Battery is reading about 12.5 when idle and 14.5 engine running. I've got it on a charge now to see if it will make any difference.

Not sure what else to do / try so any ideas are greatly appreciated.

Chris, with my pump, aside from the previous owner using normal PS fluid which is incorrect and to heavy for the pump, once the pumps controller unit is on the way out, your pumps had it and sadly you will need to replace the pump. I tried to service mine but again, it was to far gone so I replaced the pump with a new ZF OEM unit as there are no remanufactured pumps here in Australia and to import one from the UK or US would cost the same if not more.

Bottom line is, its a new pump.

Yip, feeling more or less the same way to be honest. On the plus side, I fixed the passenger window with a few thumps and the rear wash with a pin and a clean!

Ha Ha Chris, I was thinking more along the lines of the rear engine mount as I have a funny shudder in 1st but im positive its not the clutch so this weekend is booked out for maintenance. Looking at those images, you can see the heat stress damage to the chips so that controller is definitely shot.
