Aux / Alternator Belt And Pulley Question...
Posted 02 July 2020 - 09:22 AM
I've tried to Google, search the forums, and asked on the Facebook group but as yet can't find the answer...
Question for the experts out there...
I recently purchased a 35k mileage VX220 turbo and decided to replace the alternator/auxiliary belt. The old belt appeared in good order with no tears or damage and I quickly removed it without any fuss... But, when fitting the new one I noticed that the belt has 5 ribs, but the guide pulley (which sits where the aircon would be) has 6 grooves... so, should the belt sit on the inner 5 grooves (closer to the cambelt cover) or the outer 5 grooves (closest to the wheel arch)... or do I have the wrong parts 🤔

I’m fairly sure there is only meant to be 5 grooves in the original alternator pulley to fit the 5PK belt. Maybe yours has been changed at some point?

Is anyone with a turbo able to have a look at their car if its not too much trouble?

Just checked for you and the turbo defiantly has 5 ribs and NOT 6
Thanks. Do you mean 5 ribs on the belt? That is what I have and is consistent with all the searches I have done.
My original pulley had 6 grooves but I removed the old belt without keeping a record of where it sat. I have been sent a picture by another member who had the same on his car. He took a photo of the belt placement prior to the change and the belt was mounted on the outer 5 grooves - i.e. the groove nearest the engine was empty.
I ordered a new OE Gates Pulley and it arrived today. It also has 6 grooves and I am going to fit it as described above.
Hopefully this info will be useful is anyone else notices the same issue when changing their aux belt.
