Oops.
Have to return the Dayco belt I have coming in from Rock auto now... :frusty:

Don't buy Gates belts for a 00 5.2L either. Mine didn't squeal til I put that on.

On a plus note, Rockauto sent me another Gates belt despite ordering a Dayco...
I'm not about to replace a fresh squeal with another fresh squeal.

So, the return shipping will be on them for wrong part.

I'm just gonna try Goodyear and hopefully 2nd the original stated opinion. No noise before the Gates, so logically, return to no noise after swapping it back out.

Just did timing chain & water pump. Still on old Gates belt, but squeal went away.

So either new water pump pulley, reinstalling crank pulley, or reinstalling accessories on their brackets... something apparently lined up and belt noise hasn't returned. Or the belt just was noisy a while til it somehow broke itself in while hanging uninstalled for 3 weeks, lol
