    I have inherited a little rattle what seems like its coming from the alternator clutch pulley, the noise has gradually got worse, when I turn the air ccon on it stops, and it seems to me when the engine is wwarm too the noise isn't as loud.

    Does any one know how tto diagnose the problem or had this before?

    Regards chris

    Sounds like the alternator pulley is seized,does the drive belt jump about a bit when its cold?
