As I'm sitting here in the garage waiting for the Pig to heat up so I can test the fuel pump, I'm listening to the AC compressor chatter its arse off. It's a non-functioning compressor off an 02 Firebird and a serpentine, so I don't want to lose the belt. Will this thing launch on me? It sounds like hell and I'd rather not make idler pulley brackets as I can't afford to mess with the AC right now.....
