| Item | Description |
|---|---|
| 1 | Intake camshaft pulley with integrated VCT |
| 2 | Exhaust camshaft pulley with integrated VCT |
| 3 | Crankshaft timing gear |
| 4 | Automatic timing belt tensioner |
| 5 | Timing Belt |
A newly developed oil bath timing belt drive is used to drive the camshafts.
Advantages of oil bath timing belt drive over an oil lubricated chain drive:
- Reduced frictional losses (about 20 per cent), thereby lower fuel consumption and thus reduced CO2 emission
- Reduction in noise
- The guide rails usual with chain drive are eliminated
Advantages of oil bath timing belt drive over a comparable dry timing belt drive:
- The timing belt is maintenance-free
The timing belt is tensioned using an automatic timing belt tensioner.
NOTE:
The instructions in the procedure must be followed for removal and installation of the timing belt.
