New water pump - Squealing?

Hi guys.

So, I put in a new water pump (GRAF) in my 2006 550i with 103k on it over the weekend. Truth be told, my buddy really did it - I just handed him tools and talked to him mostly.

Anyway, we got the new pump in and everything was tight with no leaks that we could tell (no overheating either), but when I started it, there was a squeal or screech maybe when it was running. We took off the belt and pulley and made sure it was tight and level/even. Started it up, still making the noise. We readjusted the belt, thinking maybe it was too loose.....still makes the noise. I ended up driving it home thinking that maybe it was just making a weird sound and it would stop once it had been broken in or something. Drove home with no issues on the temp of the engine, but the squealing didn't stop. I've put about 50-60 miles on it and it continues to do this. It is fairly low/quiet at an idle, but it gets louder as I accelerate.

Other things: 1. Same pulley that was on it (no squeals before, only that banging/knocking sound the water pump makes when it is about to go out). 2. same belt, looks to be in good condition. 3. We did this in his apartment parking lot with "regular" tools

Any ideas or thoughts? Anyone else ever have this happen?

Chad

Double check over,
1) the damper pulley (big one) where the serpentine belt goes around it. This one usually taken off instead the the main shaft when replacing WP, they are 8-torx bolts are all eight tighen in criss-cross pattern?.
2) If you installed new serpentine belt, I'd loosen the belt-tensioner a tad. Then after two weeks adjust tensioner again, new belt is shorter than older one and will pull on bearings tighter (bearing of WP, Alternator, idler etc).
3) did you clean the old WP gasket from engine block, if not there may some swivel for stacking old gasket with new one. therefore the WP is not perfectly perpendicular to belt.
4) unlikely but either your new WP is defective (the bearing is) or your alternator bearing is on the way out.

GL.

After ordering that Graft water pump and comparing it visually to old OEM I returned it next day and got OEM water pump from Palican parts. There is a big possibility that it is defective.

When we were hearing the sound, it sounds as if it is coming directly from the WP itself - which is leading me to think that I got a bad unit. I've emailed PartsGeek.com to let them know so we will see what they have to say. I'm just not happy that I'm going to have to do the work all over again.....

It sucks because a the few reviews there were on the part were all positive...
