I have a 2004 GT jts 16V. I haven't driven it for 4 months. Started it after charging battery and the aux belt started to smoke so I shut it off. Long story short, guy wants to buy it and insisted on a quick test drive( he said he was a mechanic and belt would be ok). Drives 100 meters, parks car and belt snaps from heat. So we check the pulleys, all o.k except alternator clutch pulley is seized. Question is...is it cust the pulley bad or the alternator...shouldn't I be able to spin the pulley if alternator is o.k. or if the alternator bearings are seized why doesn't the pulley spin? Also, how does it get so seized up in 4 months. It ran fine when I parked it 4 months ago.
