• O-ring hose port, threaded outlet, aluminum housing, press-on pulley attachment

Detailed Description

The Cardone Power Steering Pump 21-5191 is a remanufactured hydraulic pump built to meet or exceed original equipment performance targets. Each unit is inspected and upgraded where needed during the remanufacturing process, then tested for hydraulic efficiency and proper valve operation before release. This makes it a practical replacement for Chrysler Pacifica owners looking for a direct-fit steering pump with OE-style function and consistent fluid delivery.

This part cross-references Chrysler 4743805AC and 4743805AD for the same application. It is designed for the 2005-2008 Chrysler Pacifica and uses a threaded outlet with a 16x1.5 outlet thread size, hose barb inlet attachment, and no reservoir included.

What It Helps Fix

• Hard steering or reduced assist at low engine speed
• Whining or noisy pump operation
• Steering effort that changes after pump replacement
• Fluid leaks from worn seals or aging pump components
• Poor hydraulic flow caused by internal wear or contamination

Installation Notes and Tips

Fits 2005-2008 Chrysler Pacifica, N/A. Reservoir not included, and an in-line filter, OE fluid, and system flush are required for warranty service on this application. If the original pulley has a loose fit on the replacement shaft, the pulley should be replaced. After installation, flush and bleed the system thoroughly to remove contamination and air from the hydraulic circuit.

If steering assist is present only when engine speed increases, inspect the flow control valve, spring, and pump bore for contamination or damage before reassembly. If hard steering remains in one direction after replacement, the steering gear may be the source rather than the pump.

Quality Assurance

Cardone remanufactured power steering pumps are tested for hydraulic efficiency and final assembly performance, including pressure, bypass, fluid flow, valve operation, steering effort, and noise. The remanufacturing process also reduces raw material and energy use compared with producing a new part.
