Horrible screech

[Nanonevol]

I have this horrible screech occasionally when I first start the car. It may continue sporadically for a mile or so but goes away once I'm warmed up. I've done some snooping around underneath but see nothing obvious. Please listen to this and see if it's anything anyone recognizes. It's the noise you hear right after the motor catches.

Sounds like a loose alternator belt. Check the "play" available when the engine is off - should be about 1/4 - 3/8".

Agree with you Peter.
If play is good I would replace the belt to see if the sound goes away. Some belts over time can develop a "shine" which can cause a slight slip and a squeal. As they warm up they get a better grip.

That would be great if it's that simple. Just had the belt off for a new radiator and water pump. I'll let y'all know when I get a resolution. Thanks

I usually need to put the wooden handle of a hammer behind there as a small lever to get the belt tight enough.

As they say at Staples, "That was easy". Thank you all. Sure did sound awful before.
