Belts and Pulleys
I have a 2003 A4 Anniversary Edition Vert. Currently has 74,000 miles. I have all the maintenance records going back to 2006 when it had 20,000 miles. There is no record of the belts or pulleys ever being replaced.
I am going to replace:
Main serpentine belt
Main idler pulley
Main tensioner pulley
AC belt
AC tensioner pulley
AC idler pulley
Does anyone have the Goodyear Gatorback belt part numbers and the AC Delco, Dayco or Gates part numbers for the pulleys? Is any manufacturer better than the others on the pulleys?

Unless the spring tension is weak on the tensioners there really isn't a need to change them. Save yourself the 150 bucks and just replace the belts. IF the belts squeal then I'd replace them. I still have the oem tensioners on my 99 and haven't had any issues.
