Hi all. My 2004 hemi has a pretty loud whining sound originating from the front of the engine. It also has a slight mechanical (very light metal on metal maybe) sound if you listen closely but the whine is by far the most pronounced. I raised the hood and it immediately draws your attention to the alternator but I noticed that the water pump (I think, it was a quick look) and an idler pulley/tensioner are very near the alternator so even though it sounds exactly like it is coming from the alternator it very well could be one of the other two. I may replace the belt anyway but I do not think it is the belt.
Am I correct that the water pump is located just below and maybe to the left if I remember correctly from the alternator? Any thoughts on how I can diagnose which one is making the noise? The temp seems to run perfectly normal. I don't want to replace the alternator needlessly (even though I guess I could return it if it didn't fix it) because the [email protected]#* thing is $175!! Thanks in advance!
