Whine in engine

Good idea. Already did this. I will keep looking. This one is a mystery. I will post solution when I figure it out. If you have any other suggestions, let me know.

It sounds like an alternator whine when it is under a heavy load or trying to charge a bad battery. It doesn't have that bearing noise like metal on metal. It kinda sings. Sounds like the old whine in your radio in the old days when you didn't use resister plugs or sheilded plug wires. It's downright irritating.

Another good suggestion. It is not a whistle typically assocoiated with a vacuum leak. It would send a service engine message if this were the problem, plus it idles too smoothly for this to be the issue. However, it's worth a double check. I'm leaning towards the water pump, even though it's not the typical bearing noise. I was hoping someone had come across this issue before. It's very hard to diagnose something when you can't hear for yourself. You would know what I mean if you heard it. I've had three of my best mechanic friends listen to it and they all thoght it was the alternator. It had been replaced when I got it. I suspect it was traded in because no one had been able to figure it out. I had a brand new one in my parts bin I put on it and the same issue remained. You are full of good ideas. Are ou sure you weren't in my auto mechanics class?

It makes the noise whether the fan clutch is engaged or not. I will retry some of the ideas. I may try running it with the fan clutch off the pulley. I replaced the belt and checked the idler bearing. Did not run it with belt off. Cleaned all the pulleys and water pump flat side which drives the water pump. Again, thanks for your imput. I am going to bed. I will check it after work tomorrow. I had to take a retirement job. I am teaching GED classes at the state prison. Helps the retirement funds. LOL
