Setup, Compatibility & Care
To ensure successful installation, always verify your existing part against the following OE numbers: 0AY598549, 0AY598549A, or 0BS598549.
Installation Steps:
- Ensure the vehicle is properly lifted and secured on jack stands.
- Locate the AWD coupling unit on the rear differential housing.
- Carefully disconnect the electrical connector and drain necessary fluids if required by your specific service manual.
- Remove the old pump using the appropriate tools, taking note of the mounting bolt positions.
- Install the new VAICO pump using the included seal ring to prevent fluid leaks.
- Secure with the provided bolts and screws, ensuring they are torqued to the manufacturer's specification.
Care: Regularly inspect the area around the pump for signs of fluid weeping. It is recommended to perform a fluid flush of the coupling system when installing a new pump to remove contaminants from the old unit.
