I have an '89 SC and there is a loud almost rapping noise coming from the engine. On taking off difference serpentine belts, I've narrowed the noise source down to either the lower right tensioning pulley or the double idler pulley right above that drives the Supercharger.
1) Is this a typical problem and is one more pulley prone to getting noisy (going bad) than the other? The tensioning pulley appears to be plastic, so I was guessing it's not that.
2) What's the procedure for fixing whichever pulley is the problem?
Thanks
