I just finished my first major project for me w/ my Z. I had to replace the water pump. While I was in there I also replaced all the belts (and pretty much anything else I could find while I was in there) Anyways - change went good. I filled everything up - no leaks. Ran it for about 20 mins - all good. It sat for about 6hrs - I just started it back up and got a loud squeek from the belts for a few secs then it went away.
Is this normal or something I should be worried about?
