X4XZ Engine Coolant Water Outlet for Ford Escape Focus Transit Connect — 902-231 OEM Replacement, Heat-Resistant Polymer

The X4XZ 902-231 Engine Coolant Water Outlet is a direct OEM-replacement cooling outlet engineered to restore proper coolant flow and prevent leaks in compatible Ford and related models.

This replacement water outlet (OEM equivalent 6S4Z-8K556-A / 8S4Z-8K556-A) is built to match factory fitment and function for a range of 2003–2018 Ford, Mercury and Mazda vehicles. It replaces cracked, brittle, or leaking outlets that can cause coolant loss and temperature instability. Constructed from heat-resistant materials and molded with factory-style mounting points, the unit installs without modification and is intended to deliver long-lasting service when paired with regular cooling-system maintenance.

Which vehicles does this water outlet fit?

The 902-231 water outlet is compatible with multiple Ford platforms and related brands across several model years. Fitment covers common four-cylinder engines used in Escape, Focus, Fusion, Transit Connect, and certain Mercury and Mazda models.

• 2005–2017 Ford Escape L4 2.3L / 2.5L
• 2005–2011 Ford Focus L4 2.0L and 2003–2005 Focus L4 2.3L

How does this part prevent coolant leaks and overheating?

By replacing a worn or cracked factory outlet, the X4XZ 902-231 restores a sealed interface between the engine block and the cooling system. A secure outlet prevents coolant seepage and maintains steady circulation, reducing the risk of localized overheating and associated engine stress.

• Precision-molded sealing surfaces reduce seep points
• Factory-style mounting points ensure even clamp pressure
• Heat-resistant material resists warping under thermal cycles

Is this a true OEM replacement and easy to install?

Yes — the 902-231 is designed as a direct replacement for OEM part numbers 6S4Z-8K556-A and 8S4Z-8K556-A, so it aligns with factory connection points and hose fittings. Most installers can complete the swap using basic hand tools; no special adapters are required.

• Direct OEM-compatible fit eliminates modification
• Pre-shaped hose connections match factory hoses
• Recommended: replace related gaskets, clamps, and coolant during installation

What materials and durability should I expect?

The water outlet is produced from reinforced, heat-tolerant polymers formulated to withstand repeated temperature changes and coolant chemistry. Its construction aims to minimize cracking and prolong service life compared with aging factory units.

• Thermally resistant polymer body for durability
• Engineered to resist coolant corrosion and stress fractures
• Quality control to match OEM dimensional tolerances

Who is this for: The X4XZ 902-231 Engine Coolant Water Outlet is intended for owners, mechanics, and fleet technicians maintaining compatible Ford Escape, Focus, Fusion, Transit Connect, Mercury Mariner, Milan, or Mazda Tribute vehicles with four-cylinder engines who need a reliable, OEM-fit replacement. Choose this part if you’re addressing visible coolant leaks, recurring temperature fluctuations, or replacing an outlet as part of scheduled cooling-system service. For ease of mind, X4XZ backs the product with customer support and a one-year product service policy to assist with fitment or quality questions.
