Dorman Engine Coolant Water Outlet 902-231, Direct-Fit Crack-Resistant Replacement

The Dorman 902-231 engine coolant water outlet is a direct-fit replacement that restores proper coolant routing and resists cracking from repeated temperature cycling.

This replacement water outlet is engineered to match the fit and basic function of the original equipment part on specified Ford, Mazda and Mercury vehicles. Built to tolerate wide temperature swings and resist leaks, it is an economical aftermarket option when the factory outlet shows signs of wear, coolant seepage, or visible damage. Use the garage tool to confirm compatibility with your vehicle’s year, make and trim before ordering.

How does this water outlet restore coolant system function?

Replacing a failing outlet ensures coolant flows correctly between the engine and radiator, preventing overheating and maintaining consistent cabin heater performance. The Dorman unit uses a design intended to mirror the OEM geometry so hoses and mounting points line up without modification.

• Direct-fit design for original hose and bolt locations
• Sealing surfaces shaped to reduce leaks when installed with proper gaskets
• Compatible with factory coolant routing on listed models

What materials and features improve durability?

This outlet is manufactured to withstand repeated thermal expansion and contraction common in engine cooling systems. Materials and construction focus on resisting cracks and warping that often cause coolant loss in older units.

• Resilient housing material formulated for high/low temperature cycles
• Reinforced mounting areas to prevent stress-related failure
• Engineered sealing surfaces to limit coolant seepage over time

Which vehicles will this Dorman part fit?

The 902-231 water outlet fits a range of Ford, Mazda and Mercury models across multiple model years. Confirm fitment by inputting your vehicle’s exact year, make and trim into the seller’s garage or fitment tool prior to purchase to avoid returns.

• Ford Escape: 2005–2017 (various engine/trims—check fitment)
• Ford Focus: 2003–2011 (select engines and body styles)
• Ford Fusion: 2010–2017; Transit Connect: 2010–2018
• Mazda Tribute & Mercury Mariner/Milan model years listed; verify exact trim

Is installation straightforward for a DIYer or better left to a shop?

Installation is typically a moderate DIY task for someone comfortable with basic cooling system service: draining coolant, removing hoses, swapping the outlet, and refilling and bleeding the system. However, if corrosion, stripped bolts or inaccessible fasteners are present, professional service may be faster and safer.

• Requires coolant drain and proper disposal or capture
• Basic hand tools and torque specifications needed for correct sealing
• Inspect hoses, thermostat, and clamps while the system is open

Who is this for: The Dorman 902-231 is aimed at vehicle owners and independent mechanics looking for a reliable, cost-effective replacement for a failing OEM water outlet on compatible Ford, Mazda or Mercury models. It’s suitable for drivers who want an engineered aftermarket alternative that preserves factory fit and function without the dealer price.
