Common Problems This Pump Can Address

- Whining or noisy pump operation

Installation Notes and Tips
Fits 2006-2008 Buick Lucerne, N/A. The pump uses an O-ring hose port, a threaded outlet, and a hose barb inlet attachment. The pulley is press-on and not included, so the original pulley must be inspected before reuse. Cardone notes that a system flush is required for warranty-related service procedures, and OE fluid is recommended. If steering assist is uneven after installation, inspect the flow control valve, clean the system, and bleed the power steering circuit thoroughly.
Quality Assurance
Cardone remanufactures this pump using tested internal components and hydraulic efficiency checks to verify pressure, flow, valve function, steering effort, and noise. The process also reduces raw material and energy use compared with manufacturing a new part.
