Last year before my trip to Mongolia I replaced my compressor with a brand new Denso unit with what looked like an oversized aftermarket magnetic clutch pulley and it all work fine until the tensioner pulley bolt broke which loosed the belt considerably and I realised that the pulley on the compressor was loose Since installed it had done about 15-20k miles with a considerable amount of off-roading so the shiny new unit was soon covered with a layer of mud/sand/dust etc. So after I cleaned the up the engine bay a bit including the compressor I took it in for a warranty repair and it was removed and sent back to the supplier who said it has somehow overheated due to the huge amount of dust inside (I assume they mean in the clutch mechanism) and will not be doing a warranty repair. They said that they have never seen such a dirty unit. Anyway they will fit a new clutch and recon the whole unit for £200 as a good will gesture.
What I would like to find out is if anyone else has had their magnetic clutch fail and if it had anything to do with off-road use (was the whole engine bay covered in a layer of dried mud?). I have a suspicion that if a genuine denso/toyota clutch was fitted I would not have this issue.
I highly doubt that the really hot Russian summer could have done this as it was above 35 degC for a good few days with but the aircon was keeping up fine with no problems.
