i proceeded to take out my sc belt at like 1:00 today. now its 9:00 and my car is a piece of crap. i loosened the tensioner puilley between the alt and crank..took off that belt...loosened the adjuster pulley for the sc belt...took it off. i tried to put the new belt on but it turned out to be too small...so i spent a load of time messing around with it....then ended up putting the original belt back on. i start the car and there's this incrediby loud grinding noise...and a metal to metal/rubber smell. what a nightmare...what should i do?
