Hey guys i need to know which pulley is located right below the alternator, i was hearing a loud noise from that area so i thought it was the bearings shots in the alternator, so i replaced the alternator and the noise is still there! Any help would be greatly appreciated. Shoebox this is what was the noise i was talking about.

 

alternator.. power steering pump.. ac compresser.. idler pulley... from top to bottom...
