Squealing Noise From Engine

Hey guys,

I just had my water pump replaced about two months ago and now my Jeep is starting to squeal when I start it up and if any of the vents are on, either it be air conditioning or just the defroster at any speed.

I had a water pump go about 2 years ago and I put on a new belt. So I was wondering if the shop that did the latest water pump did not tighten the belt enough or if I have an idler pulley going. What do you guys think?

Hallo. Try to adjust the belt first. Maybe it is seated well now after 2 years.
