Many people have pin pointed it. Its usually the idler pulley or belt tension or. I've had both go the idler really caused the chirp only on cold start up

run it without the serp belt on and see if the noise goes away. if it does, you've isolated it to alt, one of the 2 idlers, ps, wp, or crank pulley. if it doesn't, remove the ac belt and run it. if it goes away, you know whete it is. both tensioners seem to be fairly problematic on these engines

the richest ones are not those who have the most, but those who need the least
