Today I was driving and gunned my car to hear a noise from the engine. It's hard to explain what it sounded like almost like a clunk/scrapping noise. I immediately let off and it stopped. My car drove fine after that, so nothing broke. Could it have been a belt slipping? Anyone know what it sounds like? I recently changed the power steering, a/c, and air pump belts. The only one I haven't changed yet is the alternator. Thanks in advance for your replies.

 

a bealt slipping usualy makes a high-pictched squealing sound, kinda like tires spinning, but higher-pitched. if it was clunking/scraping, i dunno what it could be.

 

HUMMMMMM................ I wish I could help but I dont know what it could be if it ran fine afterwards!
But like Drifter said above a slipping belt is a loud high pitched sqeal!

 

bad bearing maybe?

 

i have a bad alt bearing. my car makes a metalic whine under acceleration. plus i loose alternator/waterpump belts because of it. thats why im not driving my car right now

 

just a wild off the head guess here, but maybe a engine mount?

 

no vibration so i don' t think it would be that

 

differential mount possibly?
