The belt was squealing on cold/damp mornings. Since I had never replaced it and I am almost at 90k it seemed like a simple thing to tackle. It wasn’t on the dealer’s list. I vaguely remember them mentioning it a while back during an oil change service but I blew it off (because it hadn’t started squealing and I’m sure they quoted me $350).
This is one of the easiest things you can replace. It’s a $30 belt, and to get it off, you just need a 15mm wrench/socket to move the tensioner to put slack on the belt. Then it’s just a matter of routing the belt properly.
