Fiat Seicento screeching sounds...what is it?

[@mattyboy47]

I scrapped this car two years ago, but hope the info continues to help others.

You alternator belt needed tightening perhaps. The screeching sound is the belt slipping for what ever reason. The cold weather can cause it sometimes or damp but it soon clears. This may clear up the mystery of people with a screeching sound coming from their engine from time to time.

I have a cinquecento with much the same problem. I had a loose fan belt a few months back which led to the battery dying, but that's sorted. Now I think my alternator bearings are worn down because it's making a metallic noise whenever the engine is running. Think a new alternator is on the cards :/

E' solo un po' di umidità sulla cinghia tranquillo è tutto regolare!

Fanbelt!

Went into the garage, turns out I have a bolt loose that needs tightening :)
