Installation Notes and Tips

Verify the vehicle uses a hydraulic power steering setup with a clamp-on inlet and threaded outlet before installation. Because this pump is supplied without a pulley and without a reservoir, reuse or source the correct related components as required by the vehicle configuration. Flush the steering system, inspect hoses and seals, and confirm fluid condition before returning the vehicle to service.

Quality Assurance

AAE remanufactures each pump by cleaning the core, replacing wear components, and testing the finished unit prior to shipment. That process is intended to support dependable operation on Mercedes-Benz SL500 and SL55 AMG applications covered by part number 5523.
