[QUOTE="LCP, post: 198697, member: 2424"] Oh yes, forgot to mention that I also switched off the aircon when the sound came on, and with the aircon off, the on and off whining sound was still there... but then the bearings on the aircon compressor is always turning, only difference is there's no load when the aircon compressor is not running. Could it be bearings failure on some other pulleys... The belt on the M50 engine sure loops around lotsa pulleys. If it is the aircon compressor bearings, what's the remedy like, replace the whole compressor or just the bearings? [/QUOTE]
