What It Helps Correct

• Hard or inconsistent steering effort.
• Whining or noisy hydraulic pump operation.
• Low hydraulic pressure affecting steering assist.
• Leaks or wear-related pump failure.
• Poor steering response after pump replacement when the reservoir is restricted.

Installation Notes

• Confirm vehicle year, make, and model before ordering; this pump is application specific.
• Replace or inspect the steering fluid reservoir during service, since a clogged reservoir can starve the new pump.
• Flush the steering system before filling with OE-approved power steering fluid.
• Verify pulley and reservoir requirements, as this pump is listed without a pulley and without a reservoir.
