Squeaking belt

My drive belt is squeaking like a squeak squeak squeak noise... it squeaks once per revolution. Am I right in thinking that the most likely culprit is the belt tensioner pulley bearings, and that if repacking them doesn't fix it then the next most likly cause is the water pump?

Sounds right on to me. My old truck did this, too. Usually when it was cooler, or damp outside. Once it warmed up, it would stop.
I am not sure how serviceable the tensioner pulley is. Let us know if you do the repair, and how it works. This would be very useful info.

The bearing in the tensioner assembly is a sealed bearing assembly, meaning no way to pack with grease. If the belt checks out OK, you will then need to replace the tensioner. Dependinng upon availablity, you my need whole assembly, or could get pulley with bearing pressed into it.
