I'm replacing the water pump and timing belt. I've got everything in place and in the process of putting it all back together when I see this washer on the ground. I have no idea where it came from, I don't remember seeing it during the tear down. After looking around and trying to see where it might fit, the best I could come up with is it goes on the bolt the holds the bottom of the power steering pump in place. Can anyone who's done these repairs recognize this washer? I don't dare finish the project until I find where it goes, it looks too substantial to just toss in the spare parts bin with the stuff that's left over after working on my jeep.
