Hello everyone, this is my first post.My mom purchased a 2004 nissan pathfinder from a used car dealership about 6 months ago. Recently, the engine has been squealing very loudly on cold starts and goes away after the engine has warmed up enough. So far Ive replaced the power steering pump, idler pulley, alternator, fan clutch, and belt. However, this morning my mom told me it was squealing again. I have no idea what it could be now. From my research these were the most common causes of the problem but ive also read it could be the harmonic balancer or water pump. My dad told me when he removed the belt and started the truck the noise went away. It sounds like its coming from the passenger side so i dont think its the ac compressor or the other idler pulley.Any help would be greatly appreciated. Thanks
