Whining noise from engine
 
I replace the power steering this weekend. Piece of cake. But after putting it On I discovered the old pump was hiding a whine to the engine. It's coming from the bell crank or inside the block (can't get my face down there to tell. Sounds like a Ford Explorer. Also to mention that this is a refurb engine with less than 6k miles on it.

Any ideas?

Water pump. Mine did the same thing for about a month just before the water pump decided to puke all over the highway.
Mine was real noticeable at lower revs and even more noticeable when the AC was on. I'm assuming it was due to the extra load from the compressor. I was actually beginning to believe it was AC related until it totally went out.

Re: Whining noise from engine
 
you can be sure its an accessory by just removing the serp belt and starting the engine... if the noise is gone it is naturally going to be an accessory, if its not gone your going to need to look elsewhere... Dont get me wrong, im not disreguarding the waterpump idea, very well could be but the belt removal is a quick and easy way to verify an area...

Furthermore if (when ;) the noise goes away after removing the belt, you can grab and spin pulleys and feel for tired bearings, either rough of sloppy on ALL accessories, idlers and tensioners.

That link didn't open. Do you hear a whine when the A/C is on? Just a thought. And what is it that you just purchased? (I can't see it because the link won't open up for me)

Re: Whining noise from engine
 
I just changed mine out a couple weeks ago. I had a whine for over a year and am so glad its finally gone! I started out replacing the tensioner and that didnt fix it, then i went to the water pump and problem solved! It really wasnt that hard. There are quite a few bolts, but i think all i have to remove was the belt, alternator, and then all the bolts holding the pump in.

Im just glad i swapped mine out before it failed on me. The whine started right after i got my new motor put in, so i just assumed it was from the intake or just the sound of the new motor. I grew tired of it after a year, pulled the belt, started her up and the whine was gone. So then i started throwing parts at it :)

I also made sure to use coolant from the dealership. Im not really a big believer that the wrong coolant could cause a problem, but for an extra $10 i figured why not. After my cam swap i had my fiance run up to autozone and grab some coolant. Ended up being the GM dex stuff which is supposedly the worst kind for the Hemi which is also why i flushed it out and went with Mopar coolant after swapping the pump.

So just the alt and serpentine belt? Psh... that cuts the time down significantly opposed to the charts posted above! I already have good experience and practice working in there too. Lol.
