Cardone 21-5370 Power Steering Pump

Remanufactured Power Steering Pump for Ford, Mercury, and Mazda

Cardone 21-5370 is a remanufactured power steering pump engineered to meet or exceed original equipment performance. It is built for direct replacement on select Ford Escape, Mercury Mariner, and Mazda Tribute applications, with design updates where applicable to improve durability and long-term operation.

Key Features

• Remanufactured Original Equipment-style power steering pump for precise vehicle fit
• Triple-tested critical components, including cam packs and spool valves, for reliability
• 100% new O-rings and premium HNBR seals to help resist heat-related seal breakdown
• Computer-tested final assembly for pressure, bypass, fluid flow, valve operation, steering effort, and noise
• Surfaced shafts to precise specifications to help reduce premature seal wear
• Supplied with calibrated pressure relief valves
• Remote reservoir design with hose barb inlet and threaded outlet

Product Details

Cardone Power Steering Pump 21-5370 is remanufactured from an Original Equipment core and inspected for functional improvement during the remanufacturing process. The aluminum housing, O-ring hose port, and bolt-on pulley attachment are configured for the listed applications, while the hydraulic efficiency test helps verify consistent output before installation. This part cross-references Ford/Mazda/Mercury OE numbers 5L8Z3A696BA and EF9532650A for the same application.

Common Steering Problems It Can Address

• Whining or noisy power steering pump operation
• Low or inconsistent steering assist
• Hard steering after pump replacement when the system has contamination or air in it
• Fluid leakage from worn seals or O-rings
• Poor steering response caused by pump wear or valve issues

Installation Notes and Tips

Compatible With 2004-2012 Ford Escape, 2005-2011 Mercury Mariner, and 2005-2006 Mazda Tribute, with fitment-specific notes for reservoir and flush requirements. Reservoir is not included. Use the correct OE fluid, flush the system thoroughly, and bleed all air from the hydraulic circuit before road testing. If the original pulley has a loose fit after removal, the pulley must be replaced. For noisy operation after installation, inspect for air in the system and recheck fluid level and condition. A filter is recommended on applications that call for it in the fitment notes.

Quality Assurance

Cardone remanufacturing includes testing of all critical components and a hydraulic efficiency check on every unit to confirm pressure, flow, bypass function, and steering effort. The process is designed to restore OE-level performance while reducing raw material and energy use compared with manufacturing a new part.
