I have already had several problems with my car - one of which was my alternator died on me. Before this was happening I was getting belt squeaks every time I started my car and with each day the squeaking would last longer and longer. Then it would squeak WHILE I was driving the car...

I decided to take it to my mechanic and on the way to my mechanic my car died while it was squeaking - alternator died...

I got the alternator replaced and recieved a new belt ect...

All was good for I would say a month... (I don't drive very much maybe 100 miles a week)
Then it started to squeak a little when I turned it on...


But it is now 5 months later and it squeaking everytime I turn it on and starting to squeak like it did before - WHILE I DRIVE!

I don't want to buy another alternator then another alternator then another alternator...

Am I being paranoid in thinking my alternator is going to die again?

I just don't know what the cause could be...
What I can do...
Or anything else =-(

well it sounds to me what is happening is your alternator isnt actually dying it just seems your belt isnt getting tightened enough ..... when you hear the squeaking belt it is the belt sliding on the alternator pully and the alternator is not able to put out enough power to keep your battery charged so your car dies i would reccommend just replacing the belt making sure your following the recommended tension guidlines and putting your battery on a charger for the night...good luck :)


when you remove the old belt look at the underside and look for nitches or anything that might show abnormal wear

Suggested Repair

Replace the drive belt, set it to the recommended tension, and inspect the old belt underside for nicks or abnormal wear. Charge the battery overnight so a slipping belt does not leave it discharged.

Conversation Summary

The owner of a 1997 Mazda Protege had belt squealing that worsened until the car died and the alternator was replaced with a new belt. Squealing returned months later and now occurs while driving, raising concern that the alternator is failing again. The expert said the belt is likely too loose and slipping on the alternator pulley, which can prevent charging and kill the car. They recommended replacing the belt, following tension guidelines, checking the old belt for abnormal wear, and charging the battery overnight.
