I just bought a 2003 Jetta 2.0 as a project car with 110,000 miles. Well there had been a rattle which I thought was probably from a loose exhaust component but was also inspecting the timing belt this morning. Well I started and moved the car to where I was gonna work on it and left it idling. As soon as I popped the hood I watched the timing belt snap. Should I bother trying to replace the belt assuming nothing else is damaged? The car ran great prior to now, minus the rattling of course. Suggestions, please?
