2002 Hyundai Sonata: Squealing problem.

I own a 2002 Hyundai Sonata. My problem is when I begin to start the Sonata and begin to Drive, sometimes it runs perfectly fine. No Engine Light, no nothing. Although at times like Today for example (Rainy Weather Conditions) the Sonata will start to make a loud, squealing noise from somewhere underneath of My Hood and the Squealing sound only seems to occur as soon as I accelerate. While accerlerating, the loud, squealing sound will go away after a couple of Minutes. Although when it is squealing, when I take My Foot off of the Accerlerator, the sound goes away. When I press the Accerlerator there it is. The squealing only seems to occur when it wants to. I could be stopped at a Red Light and Go once it turns Green and the Sonata would Run perfectly fine. Other times, it be very loud. When I start the Sonata it runs fine. Just the odd time when I do accelerate there it is. While it is Squealing there is no Engine Light. My Mechanic just put a new Belt on the Sonata to Stop it from Squealing but it is still there. I even have a Brand New Altinator that was put in it. Every once in awhile My Engine Light will come on and it is P4055. Which is a Gas Cap which wouldn't have anything to do with the Squealing so that isn't the problem. My question to You is, what would be causing this Squealing? Thought at first it was a Fan Belt issue but Mine was just replaced and brand new same as My whole Altinator. If it means anything, My 2002 Hyundai Sonata does have low Mileage at just over 118,000Km. It's already undercoated and has been every August. Listed below is what has been done to the 2002 Hyundai Sonata.

BRAND NEW:
-- Radiator & Battery.
-- Gas Lines & Brake Lines.
-- Sway Bar Mount & Oil Pan.
-- Front & Back Frame.
-- Altinator & Fan Belt.
-- Alignment.
-- Sway Bar Link.
-- Inspection. (August of 2013).
-- Wipers.

If You can help Me find out as to what My squealing problem is it would most greatly be appreciated!.

Remove or loosen the tension on the new belt so you can hand spin all the pulleys. The crankshaft being the exception. I'm thinking one or more of them might be hard to turn. If they all check out ok, check for glazed pulleys. Badly glazed pulleys and a new belt is kind of like wearing hiking boots to walk across a frozen lake. No traction.

Thank-You for the advice. I will see if that happens to Work. This Car has a lot of Life left in it and I don't want it to see it kick the bucket over alittle thing. I might be looking at a lot of Money though if We are Talking Pulleys. =/

You can change both pulleys yourself for under 75.00, if it is the the AC compressor or the power steering pump it gets a little more expensive, but still not out of the park....The detailed replacement list does not included a timing belt...at 118k miles this should be the first thing on your list to get replaced... Because if the timing belt breaks, the valves will bend and the repair cost will exceed the value of the vehicle...Timing belt cost eighty bucks at Autozone, 275.00 to replace depending on your location...

I think it is the water pump should be replaced with a new one, Check if there is a water leak under your car after a short park for 15-30 minutes near to the front right wheel
