Air Conditioning pulley

[Greeny]

When I turn on the A/C, the engine revs drop a little,to be expected, but the pulley gets really hot and starts to smoke. Do I just replace the pulley, or is it a symptom of something more sinister. Cold air does come from the vents, although I have not run it for long due to the smoking pulley. Any advice welcome!

If the smoke is coming from the pulley then surely it's the belt slipping (very badly)!

[Greeny]

No, definatley from the front of the pulley.

Maybe the pump is buggered, bearings gone? I think someone on here had one explode a few months ago. Nasty business.

the pulley on the compressor has an electric clutch on it sounds like that is FKED to me

Thats what I was thinking. So just change the pulley then?

Had the same problem in my 840 and eventually changed the whole unit for an exchange one. Cost was £220.00 fitted
