Timing belts transmit drive power to the camshaft(s) from the rotating crankshaft thus enabling the intake and exhaust to open and close in accordance with the valve timing pattern specified for each type of engine.

Necessity of maintenance /What happen if not done

The timing belt gradually becomes worn, hard or slack as it is used ,and it will finally jump over the sprocket teeth, and in the worst case , break.
If timing belt jumps over the sprocket teeth;
  • Engine power will decrease
  • Fuel consumption becomes worse

If belt tension becomes too low;

  • Belt vibration noise will be notified

If timing belt breaks;

  • Intake /exhaust valves and pistons will crash with each other and will be damaged

Maintenance Interval

Replace every 100,000km or sooner, depending on usage conditions.(There is no need of replacements for timing chains, which are basically maintenance free)
