When should accesory belts be replaced? I have almost 89k miles on my car and getting prepared for the winter season and snowboarding trips. I don't want to get stuck on the road if the belts break.

 

Definitely a good idea to look at them. If they are cracked and missing pieces, change them. I haven't looked at the FSM because I don't have one, but I don't believe there is a specified change interval. That's a lot of miles though, so I would say definitely consider it. It's not too hard, but you may need one of those swivel top wrenches for the PS belt...I did.
