Alright, My 86 supra is making that belt slipping noise when I first crank it. Then it keeps sqweeking untill i drive a little bit and warm the car up. Well I wouldn't even had bothered posting this if i wasn't stumped. I tighted the belt tensioner thats on the compressor pully. It seemed to do a little good but not much. I'm not sure what is making the noise. What else can sqweek in that area? Is there anything else i can tighten?
