All the belts were done 40k ago.
Think the issue may be the aux belt tensioner.
There is another poster on the forum who posted a youtube clip with the exact same sound but he seems to have not finished posting a result except to say he got to using soap or similar to quieten the belt.
Is the aux belt tensioner pulley plastic or metal?
Just cant quite figure out why it suddenly gets so loud only when the aircon is engaged.
