Do not attempt to change your timing belt if you don't have the tools, and the know how. You must have at least a timing analyzer and a timing light. If you have all of the above, you may go ahead. It's one hell of a job. Open the hood of your car. Take the valve cover off. And
the timing belt cover. Loosen the idler, so you
can take the belt. But first make markers so you can return everything to its original position.Otherwise, have it change at the service center, by a qualified mechanic to do it right.
