304 Bearing noise

[Clivevt5.0]

hi, I’ve got what sounds like a bearing noise but not sure what pulley or tensioner it might be. I’ve recently replaced the water pump so doubt it’d be a new w/pump bearing but stranger things have happened haha. Just wondering if anyone has had the same problem/s and if it’s a simple as changing a tensioner pulley that may be noisey. Haven’t gone as far as using a screwdriver to pin point which one it may be.

Cheers
