finally had time for a test drive after the OE belts failed, for some reason they were chewed on the top end and were riding too deep in the groove to drive the compressor, yes they were squealing pretty bad with AC on. Bought a new set but could not find a matching set, and after 90min of highway driving the voltmeter dropped from 14.4 to 13.4v and 13.2 with AC on. Stopped at a local parts place to test the system, all good, my 13.4 is 13.8v, and yes the belts have stretched, I retighten them and ONE is more stretched than the other, and has turn less than the other, I aligned the label on installation.
So is there a way to find a matching pair of belts? I have the masterpro 7508 now. Probably should get Gates!
thank you
