XC90 V8 Accessory Belt Replacement

While replacing the alternator, I noticed the accessory belt looked a little rough. The edges of the belt was showing signs of wear and there were some cracks forming in the belt’s surface. Since I didn’t have a spare belt on hand, I just reinstalled the original belt back on when I buttoned the car back up.

Here are the specifications on the belt:

  • Length\Circumference: 99 inches
  • Width: 0.82 inches
  • Number of ribs: 6
  • Dayco part number: 5060990

The brand of the belt I got was from Dayco – the part number was 5060990 and cost me $25 from Amazon.com. I purchased it from Amazon because I had several gift cards from there so it was essentially “free” for me – there are other places that also sell the belt and it is also made from several different manufacturers. Here’s a list of part numbers and prices from RockAuto.com

  • Goodyear – 4060990 – $11.95
  • Dayco – 5060990 – $16.65
  • Gates – K060990 – $21.99
  • AC Delco – 6K990 – $24.79

Did you find any of the information useful? Have I helped you save a bit of money / time / frustration? I've spent a lot of time taking pictures and meticulously documenting everything to post it here. I'd really appreciate it if you could send me some money via Paypal! This helps defray the cost of running this website and also provides me with beer to continue writing these articles. Thanks!
