...now my car is making a whining? noise when i acclerate you cant hear it as much because of engine noise but when its at idle the squealing noise is somewhat loud does anyone know what it could be ? its not the water pump because i bought it new and im not overheating and the belts arent too tight either i have already checked them
no its not the alternator because i bought a alternator from jegs and its like 3months old and the i turned and theres no sound
 
When I was a kid and had my 53 Chevy 2 dr hard top with a 327 Chevy engine in it. I remember it having a squalling. Kinda sounded like belts or pulley or alt. nope I found out what it was. It had just rained and for some reason the crank shaft seal or timing cover seal drys up and was making a squealing sound. All I did was squirt WD 40 and problem was fixed. But do remove the fan belts and start the engine as to try and eliminate the problem. Good luck
 
Take the fan belt off and spin the water pump by hand. If it's dead silent make sure the new water-pump outer flange is holding the pulley directly over the pulley's on the crankshaft. If they aren't in perfect alignment or you hear noise tear the pump off and take it back. The outer pulley flange or noisy impeller makes it a candidate for a new pump.

Why not get your money back from the whining pump and order a Stewart or Moroso aluminum racing pump for a few bucks more.
