When a timing belt breaks, costly internal damage could occur. Timing belt are normally used on smaller engines but hardly used on bigger engines.

The timing belt is not like the alternator belt, fan belt or power steering belt where by they can be easily seen during maintenance. The timing belt is made from the same material as the rest of the belts and will wear out. Timing belt will not last forever.

The function of timing belt is to keep the camshaft to be exactly synchronized with the crankshaft and distributor. The engine will not run if the camshaft and the crankshaft are not in synchronization.

Apart from that, if there’s no synchronization and when the piston which coming up the top of its cylinder and at the same time the intake exhaust valves are opening, the piston could hit the edge of the valves.

The valves could break or bent and the cylinder can’t be properly sealed off and the engine will not run properly. It won’t make any difference if you replace the timing belt after this because you will need to replace the valves in the cylinder head as well.

Hence it’s important to change the timing belt at a recommended interval i.e at 100,000 km (or 60,000 miles). It’s advisable also to replace the water pump either after the milage reaches 100,000 km.

If you’re not sure when to replace the timing belt, just check with the manufacturer or dealer.
