all mine are changed at 58k, currently at 61k. one of the belts constantly keeps screeching when ever i turn the car on when its cold. arround 1200-1800rpm it just screeches very loud and it is very embarrassing. which belt could it be? even when the car warms up i can somwhat hear it when i turn of throw it in neutral. im going to tr to fix it tommarow morning. when ever i open the hood though the screeching goes away, the hood doesnt cause it but the car is playing games with me i swear! haha

Could be any of the 3. Are they all properly tensioned? Also, this should be in tech.

If it squeals when you turn, it's probably your power steering belt that needs to be tightened. Since you only installed them 3k miles ago, they have probably stretched a little after getting broken in, which is totally normal. I'd give each of the tensioner bolts a good turn or two and see if it helps.

yeah, manual tensioners on all the drive belts on these cars. just re tighten all 3 while you in there. takes 5 minutes.
