| Alternator squealing! 2016 Peterbilt 389 with 12.7 liter Detroit 60 Series. New alternator. New pulley. New tensioner. New belt. Cranked the truck up. No problem. Turned the AC on and it started squealing like a pig. Turned AC off and it went back to normal. The AC was working just fine before. Put in 2 new pressure switches. Checked freon level. Clutch is working. Pulley spins freely when we spun it without the belt. Any help would be greatly appreciated. The water pump is also running on the same belt. | |||
