It regulates engine coolant flow at 180°F (82°C) to support stable operating temperature and consistent cooling system performance. This application covers a wide range of Ford, Mazda, Lincoln, and Mercury models, including Ford Escape, Ford Fusion, and Mazda 3 fitments.

Key features

• Integrated housing thermostat design for applications that use a combined thermostat and housing assembly
• Start-to-open temperature: 180°F / 82°C
• OE performance rating for factory-style temperature regulation
• Three bolt holes for secure mounting
• Jiggle pin weep hole and jiggle pin/check valve design
• One seal included in the assembly
• Non-electric thermostat construction

Product line details

Gates Integrated Housing Thermostat products are built for modern cooling systems that rely on integrated thermostat housings rather than a separate thermostat alone. Gates focuses on aftermarket coverage for these OE-style assemblies, giving technicians a direct replacement option for vehicles that require precise coolant temperature control.

Detailed description

This Gates thermostat housing assembly is engineered for direct replacement in many Ford Escape, Ford Fusion, Mazda 3, Mazda 6, Mazda CX-7, and related applications. Gates 34044 uses an OE-temperature 180-degree opening point to help maintain the engine’s intended warm-up and operating range. The integrated housing format, three-bolt mounting pattern, and included seal support a clean service replacement on vehicles that use this style of cooling system component.

Compatible With 2005-2014 Ford Escape, 2006-2014 Ford Fusion, 2007-2013 Mazda 3, 2003-2013 Mazda 6, 2007-2012 Mazda CX-7, 2001-2011 Ford Ranger, and additional listed Ford, Mazda, Lincoln, and Mercury applications. This part cross-references Motorad (e.g., 439-180, 512-185) for the same application.

Common issues this part can address

• Engine running too cool or too warm due to thermostat control problems
• Coolant temperature instability during warm-up and normal driving
• Leaks at the thermostat housing interface on integrated designs
• Service replacement needs on OE-style cooling system assemblies
• Fitment requirements for vehicles that use a 180°F thermostat specification

Installation notes and tips

• Verify engine configuration and electronic-control requirements before ordering, since fitment varies by model year and trim.
• Confirm the housing style, bolt-hole count, and outlet dimensions match the original part.
• Inspect the sealing surfaces and cooling system condition during installation.
• Bleed air from the cooling system after service to restore proper coolant circulation.
• Use the vehicle-specific fitment notes for applications such as Ford Escape, Ford Fusion, Mazda 5, and Mazda Tribute.
