2012 JKU Belt Squeal

My 2012 JKU has what I think is belt related squeal from a tensioner being loose or bad. I'm having a hard time finding a picture so I can identify the location of the tensioners. I dropped it off at service ten days ago. The service manager even heard the noise over the telephone, but Murphy's Law hates me and of course it didn't make the noise once it got there. They changed the coolant per Chrysler, which I am pretty sure is unrelated. It's not making the noise consistently now, but I thought I heard it start earlier. I just recieved it back today. I'm thinking they just put conditioner on the belt and sent me on my way. I guess time will tell. Anyone else have this issue?

I had what sounded like a belt squeal turn out to be the water pump. Maybe that's why they flushed your coolant...

The front driver's side belt on my 2012 sometimes squeals/grinds/chatters (sort of a combo sound) when I extend it. Typically only happens when it's been sitting in the sun for while. I figured it was poor lubrication on the tensioner.

And no, it's not the water pump -- unless the water pump pumps coolant without the key in the ignition or the engine running.

I was planning on complaining about it when I take it to the dealer the next time to have some other warranty work done.

The water pump is on back order all over the place. That means they use alot of water pumps.
