Timing Belts.







''Change timing belt to avoid costly engine DAMAGE.''




TIMING BELTS or CAM BELTS simply are a toothed rubber composite belt that does a similar job as TIMING CHAIN. The job of a Timing Belt is to keep the CAM SHAFTS that control the opening and closing of the VALVES in time with the CRANKSHAFT that controls the PISTONS in a FOUR STROKE ENGINE.



I recommend to change TIMING BELT every 5 years or 100,000 km which ever comes first. If you have just purchased a vehicle that is over 5 years old or 100,000 km you should change the TIMING BELT or check that it has been done. Especially if you plan to keep the vehicle for 5 years or more.


If your accessory belt/s are worn out or cracked then it may be time to change the TIMING BELT.
When the engines WATER PUMP is leaking, noisy or ineffective the TIMING BELT may have to be removed to replace the WATER PUMP. Once the belt removed it is recommended to change the TIMING BELT unless it has been recently changed.
Damage caused by a snapped TIMING BELT can be the PISTONS colliding with the VALVES. This sort of damage generally means that the engine needs to be rebuilt or replaced. A rebuild would include replacement of bent VALVES and smashed PISTONS.
