My air pump seized on the interstate Monday. Installed a remanufactured unit today and got everything back together with new fan - and alternator belts, and I'm very clearly having the alternator belt making contact with the outer edge of the air pump pulley... The only thing I changed was the pump and used the old pulley, and it only goes on the one the pump way from what I can tell. I put the pulley on backwards at first and it made contact with the pump itself, which seemed a lot worse than contacting the alternator belt. Am I missing something? I double checked for spacers or anything that I might have overlooked but I haven't seen anything. Would appreciate any insight.
