Howling NEW waterpump?

anyone else experience this?

Brand new from FORD waterpump. The job went as easy as could be...Perfect, no issues -thanks Maintain!!!. ran it for 1500 miles...Perfect.

one day i heard what sounds like a fan belt howl....Nope not the belt. removed it and started spinning pulleys. When i spin the waterpump/fan pulley, i hear what sounds like friction but, it doesn't sound metalic (bearings). It sounds like tight rubber seals or something.
If I spin the fan clutch by itself (by spinning the fan with the belt installed, truck off...lol, obviously), no noise.

i tried a little PB blaster on the backside of the pulley...soaked it pretty good...no diffference.

once the truck goes over 1500 rmp or so, the sound is apparent. At idle, it can barely be heard and is inconsistent....sometimes it's not there at all, sometimes it's intermittent but, it's always constant if the trucks been over 1500 rpm.

wierd i tell ya...

my coolant is a little overfull -1/2" above the line...can't imagine that being a problem...
maybe i have air trapped in there somehow?

i really don't want to do this waterpump again.

open for suggestions.

thanks!

Might just be the tightness of the new bearings and seals. I would drive it if there are no other problems. If the problem gets worse then the new water pump may have problems. But I think the problem will go away as the new bearings wear in a little and the seals loosen up a bit.

thanks!

that's the tact i'm taking....it's just weird that it went for the first 1500 miles without the sound.

BTW: it did seem a little better today - pulled into work after 1/2 hour drive and it was silent. -fingers crossed
