What's left of the serpentine belt. It shredded.
Had to remove the air inlet manifold. Actually wasn't too bad, once I got past some sticky fasteners.
There's the culprit. Idler pulley, completely seized. Wouldn't turn at all. Pulled it off, and this is what was left:
Incidentally, that's not what it's supposed to look like.
So I walked down to the NAPA on the corner for a new serpentine belt and a new idler pulley. Unfortunately, they were sold out of the idler pulley that I needed. The only one they had was slightly larger, like a quarter inch. It may not sound like much, but it is. I had to get a slightly larger serpentine belt to compensate.
The new idler pulley is a different style as well. Not really a big deal as long as it works.
Did I mention the shredding? See all that stuff that's wrapped around the fan core? That was a pain in the ass to remove.
There we go, all installed.
The clearance is kinda tight, but it's clearance.
It runs, and all is happy. Yay!
But now I am cold. Very cold.
