well if it was his timming belt his car would not be running at all, also since our engine is interference you could of messed up some were and messed up the engine what I mean by interference is that if you Fudge up the timming you F** your car up which can lead up to a blwon engine, I use to work at a chrylser dealership and I saw that happen to a Sebring the timming belt broke and well the engine went bye bye so take it to a shop and let a mechanic look at it to be on the safe side also take it to some one you trust so that they want try to rip you a brand new ass hole
