The mechanic's rule of thumb about timing belts is that you should change yours every 6 years or 60,000 miles, whichever comes first. However, taking your auto to your local dealer to have your timing belt replaced will end up costing you a hefty chunk of change. Save yourself some serious dough by installing a new timing belt yourself. If you have the know-how, AutoAnything has the OEM-quality timing belt that you need to get the job done right. You get free shipping and a 1-year lower-price guarantee with your order.
