Detailed Description

This Cardone Power Steering Pump 21-5220 is built for 2000-2001 Mazda MPV models and is designed around the original equipment layout for a direct-fit replacement. The remanufacturing process focuses on hydraulic efficiency and component-level testing so the pump delivers stable steering assist, proper pressure control, and reliable fluid circulation. The unit uses a bolt-on pulley attachment, a threaded outlet, and a hose barb inlet, with a sealing kit and instruction sheet included in the package contents.

Cardone’s remanufactured power steering pump line is centered on OE fit and function, with design review and upgrades applied where practical to improve durability over the original part. This makes 21-5220 a practical choice for Mazda MPV power steering service when the original pump is worn, noisy, or no longer maintaining correct hydraulic output.

This part cross-references Mazda LC6232600F for the same application.

What It Can Help Solve

• Whining or noisy power steering pump operation
• Hard steering caused by weak hydraulic pressure
• Loss of assist at idle or low engine speed
• Fluid leakage from worn seals or aging pump components
• Inconsistent steering effort from a failing pump assembly

Installation Notes and Tips

Fits 2000-2001 Mazda MPV, N/A. Reservoir not included, in-line filter required, and OE fluid plus a full system flush are required for warranty coverage. Before installation, inspect the pulley fit, flush the steering system to remove contamination, and verify the flow control valve area is clean. If the original pulley has a loose fit after removal, replace the pulley rather than reusing it.

After installation, bleed the system thoroughly and confirm proper assist at idle and during steering input. If steering effort remains uneven, inspect the steering gear, fluid condition, and any debris in the hydraulic circuit.

Quality Assurance

Each unit undergoes hydraulic efficiency testing and final computer testing to verify pressure, bypass, fluid flow, valve operation, steering effort, and noise. Cardone also uses new seals and calibrated relief valves to support long-term reliability. The remanufacturing process reduces energy and raw material use compared with producing a new part.
