HELP keep chewing up serpentine belts
I have a 1988 Ford F-150 6cyl. 4.9ltr - and it keeps chewing up serpentine belts - like 5 so far. I have replaced the alternator, power steering pump, smog pump, a/c pulley, belt tensioner, and the water pump was replaced about 3 years ago. All aforementioned parts came with new bearings.
Problem started when the alternator lost a housing bolt, and I replaced the alternator and belt. And yes, I am using the correct size belt. I'm a motorcycle mechanic for 30+ years now, and I am completely baffled by this. PLEASE HELP
