The function of the timing pulley is to exert appropriate pressure on the timing belt
If the timing tightening fails, the engine will have performance problems because the moving parts of the system will not run at the same time.
This is caused by the loss of tension in the timing belt.
Several main components of the engine, including alternators, pumps, power steering pumps and air conditioning compressors, are connected by the timing tightening wheel
It is important to ensure that the timing pulley is not worn, so that the timing belt can be kept safe and running uninterrupted
