Installation Notes

Verify the vehicle’s original alternator matches the Bosch 70 amp, 12-volt, internal-regulator, clockwise-rotation, without-pulley configuration before installation. Confirm the application notes for your Volkswagen Beetle, Golf, Golf City, Jetta, or Polo, since fitment varies by model year and body style. Compare the connector, mounting points, and pulley arrangement to the removed unit before final installation.
