I just installed new; OEM Tbelt, OEM tensior, OEM idler, OEM water pump. Followed FSM to the T. Started to bleed the system, then right when it got to 150F, i heard a high pitch squealing noise from the Water pump. After 15 min it kinda went away, but still alittle noticable. Just wondering if there's some wierd break in period( doubt it) or maybe it was a storage issue. Any thoughts will help.

Did you replace your timing belt tensioner and idler when you replaced your timing belt?

he already stated that above... possibly over tightened your timing belt... might want to check that out. Remove the timing cover and inspect.
