The timing belt is an essential part of any naturally aspirated engine, since it synchronizes the crankshaft and valves. In order for conventional internal combustion engines to work properly, the valves must open and close in perfect synchronization—to within nearly a thousandth of a second.
The timing belt has teeth on the inside and is protected by a cover. Your certified NAPA AUTOPRO technician will inspect the timing belt during routine maintenance to check for any defects. The timing belt should be replaced according to the manufacturer’s recommendations—usually every 100,000 km.
A broken timing belt will cause your vehicle to break down immediately and have to be towed. A broken timing belt can also cause major damage to the engine. Your certified NAPA AUTOPRO technician can replace the timing belt according to extremely specific parameters and repair any engine damage.
