I have a loud "shrieking" coming out of my engine bay ever since I took of the intake manifold. I swapped out my air pump for another and changed the alternator and main belts and you can still hear it and its loud. Anyone have any suggestions? It seems to be coming from the left side of the engine bay. Water pump possibly? Does the water pump make noises when its bad? Thanks guys

in most cases the waterpump leaks if it's bad. Try to find yourself a stethoscope and listen where the noise comes from. could also be the pulleys making that noise... check the belts as well like 9Base3 says.

I replaced the belts wth brand new ones. Well at least the alternaor belt and the one on the far right, main drive bel?. Doesn't the water pump belt run off the alternator belt .Are there any others? The belts are tight. Thanks fdboost, I thought it might be because of the location the noise was coming from. Anyone ever have any simular problems or ever heard of any. I'm pullin my hair out on this one!

It could be your waterpump bearings.. Mine is in the same condition. I thought it might have been my idler pulley bushing at first but after replacing that it was still squealing. After pulling everything off in the process of going single, I spun the water pump around and realized that it was the culprit. It doesn't feel loose at all but it sure does squeal.
..For what it's worth.

yeah they have a seal on the shaft, and the weep hole lets the water leak before it gets to the bearings
