I had a 3/8 belt originally and went to ½ with an 80amp alt upgrade. It fits all pulleys on my 3HMF. That helped.

So my 80 amp Balmar has me going thru fan belts more than I like (2 x year). Three options: reduce alternator output...no. Serpentine retrofit kit. Yes, but at $500 I would like to spend tht elsewhere. Third option is buying a better quality belt for the QM series. Read much online, but would like opinions of folks who may have same configuration. Thanks in advance. David F. Risch, J. D. Gulf Stream Associates, LLC (401) 419-4650
