In the latter case, it is required regularly (when performing maintenance, every 15,000 km) check the condition and tension of the timing belt and change it every 75,000 km.
Recommendations. With the automatic tensioner, there is no longer any need to check and adjust the timing belt tension. In addition, the service life of the belt itself is significantly increased in such a drive. However, this does not exclude the failure of the tensioning mechanism or oil leakage through the shaft seals. And if oil gets on the toothed belt, its service life will be significantly reduced. If the teeth on the belt break, the valve timing will be out of order and may cause serious engine damage. A broken belt will inevitably cause the engine to stop. Taking all this into account, on engines with an automatic tensioning mechanism, it is advisable to check the condition of the timing belt, and if defects are found, replace it.
