In this review the KAX power steering pump is evaluated as a direct replacement option for owners of Fusion and Milan with the 2.3L engine from 2006 to 2009. The bottom line: it is a practical, value-oriented pump for someone seeking a straightforward swap that restores steering assist without complicated modification. The reviewer found the construction and fitment references useful for confirming compatibility, and the pump's tested operation and noise reduction claims to be the single biggest reason to consider it as a replacement unit.

Key Features

• Vehicle Fitment: Designed specifically for Fusion 2006-2009 2.3L and Milan 2006-2009 2.3L so buyers can match year, make, and model before purchase for a direct-fit replacement.
• Reference Numbers: Includes multiple reference part numbers such as 21-5179 and 6E5Z3A696AB to help verify compatibility with existing OEM parts.
• Durable Construction: Built from aluminum and iron components that resist corrosion and handle elevated under-hood temperatures for longer service life.
• Included Components: Supplied with a press-on pulley and no oiler in the kit, which simplifies the parts list for routine replacement jobs.
• Connection Details: Outlet inner diameter and attachment types are specified, with a 14x1.5 in outlet and hose barb entry to aid in matching existing hoses and fittings.
• Noise Reduction: Production testing and performance checks are intended to reduce abnormal steering noise during operation for a quieter driving experience.

Who It's For

This pump is best for DIY mechanics and independent repair shops working on Ford Fusion or Mercury Milan models from 2006 through 2009 with the 2.3L engine who need a straightforward replacement that aligns with OEM reference numbers. It suits owners who prioritize corrosion-resistant materials and an exact-fit pulley style so installation is familiar and quick.

Those who should look elsewhere include drivers with different model years or engines, vehicles with modified steering systems, or shops that require a kit with an oiler included; confirm fitment with the listed reference numbers before ordering to avoid incompatibility.
