Timing belts are critical compenants to ensuring a reliable running engine. The timing between camshafts, valves, pistons, and the crankshaft are so precise that if it is off even just one degree, the engine may not run or worse cause severe damage. This is why it is so important that the timing belt and tensioner be in good working condition all the time.

Unfortunately, like other rubber componants, timing belts wear out and must be replaced. Most manufacturers recommend that the timing belt be replaced on schedule, as a form of maintenance. This is typically at 90,000 miles, but see our timing belt replacement guide for vehicle-specific information.

If the belt isn't changed it will eventually break. If this occurs the engine will stop running and will not restart. However, on some vehicles the engines are refered to as "interference engines."

In "interference engines", when the timing belt breaks severe internal engine damage can occur. This usually involves open valves becoming bent as they strike the pistons, which results in expensive engine damage. In worst case scenarios, the engine may need to be replaced.

If your vehicle is not an "interference engine" it is known as a "free-running engine". In these engines if the belt breaks the engine will stop running and will prevent internal damage from occuring. While you will still need to be towed to a repair facility, usually a new belt is all that is required to make the car run again.

On most cars with timing belts, the water pump is also driven by the timing belt. While it is not required, it is recommended that the water pump be replaced at the same time as the timing belt because these also wear out over time, and you can save yourself some of the cost of labor by having the two replaced at the same time.
