A common cause for premature alternator clutch pulley failures can be due to a tensioning issue. Often the pulley is blamed but the main reason for the failure is due to excessive tension being applied to the pulley. Before replacing the alternator it is highly recommended that you inspect the original old unit alternator pulley for any defects. Check that the internal fan is turning when the pulley is rotated.

Check the function of the clutch pulley mechanism. If the pulley is not functioning as it should then you have a pulley failure, this indicates that a vehicle fault need investigating before the fitment of the replacement alternator as failure to do so may cause premature failure of the pulley on the replacement unit.

If you don't see the engine size you're looking for this may be because the manufacturer describes it by rounding up or down incorrectly for marketing purposes, e.g, a 2.1 litre engine may be listed as as 2.0 or 2.2 in a small number of cases. If model is 'Various' engine size will be listed as '0.0'.
