Is it a big job to change a timing belt in a 2002 vw jetta?
Its not a big job, most certainly it is not a job for a novice or someone who does not have a decent tool kit. A decent DIY mechanic can do it if he follows a Haynes manual. Best thing to do to make the job easy is mark the camshaft pulley in two places with white paint, forget looking for the little indentations the manufacturer have put on the pulley.AND before you even try to start the engine check and check again that everything is correct !!!!
