I own a Toyota Corolla 2003 CE. The engine hosts only one serpentine belt for the crankshaft pulley, the alternator pulley, the water pump pulley, the automatic tensioner pulley and the power steering pulley. I recently installed a new Gates serpentine belt because the old belt started squealing. I thought that after installing the new serpentine belt my troubles would be over, but my engine still squeals. The only time it squeals is when I start the engine; I can accelerate, turn on/off the A/C and it still squeals. It doesn't squeal forever though. The sound lasts for about 15 minutes. I can't hear the sound when I'm cruising on the highway and after I have been using the car for a while the sound seems to have disappeared.

Does anyone have any insight or explanation as to why this may be? I am at a lost in my diagnostics...

Did you check all the pulleys before installing the new belt, to check that one of them isn't close to seizing? (water pump, especially). If everything turns freely, I'd suspect that the belt wasn't tensioned correctly; you don't want it too tight or too loose.
