Generator Characteristics
Based on engine variations, different types of generators were installed.
On vehicles with a 6-cylinder gasoline engine, the generator has the following features:
- The generator is driven by a ribbed belt.
In vehicles with 6 cylinder TDI engines, generator has the following characteristics:
- The generator is driven by a ribbed belt.
For vehicles with 8 cylinder engine, the generator has the following characteristics:
- The generator is driven by a ribbed belt.
- The voltage regulator cannot be replaced separately. If a repair is necessary, the entire generator must be replaced.
- The generator is cooled by the engine coolant circuit.
On vehicles with a 10 cylinder TDI engine, the generator has the following features:
- The generator shaft is driven by a clutch bolted to one-way clutch on generator side. On the engine side, a hub grabs in the clutch. This hub is connected by a shaft to a gear in the engine control.
- The generator is cooled by the engine coolant circuit.
- The voltage regulator cannot be replaced separately. If a repair is necessary, the entire generator must be replaced.
