Timing belt components squeak?

Well, off to the dealer I guess. They need to figure out why I've had to add 740ml of coolant this year as well as this newly developed squeak. It only happens on cold start. I removed the serpentine to rule out alternator, compressor, tensioner pulley and the belt itself, but the squeak remains.

Sounds like a dry bearing.

Call back from dealer. Top timing belt roller bad... wow. At 34k. Be attentive and listen for issues, friends.
