Detailed Description

Motorad Standard part number 306-180 is an engine coolant thermostat engineered for direct replacement in select Ford, Mazda, and Mercury vehicles. The 180F temperature rating helps regulate coolant flow at the specified operating point, while the copper case and wax compound support fast response as engine temperature changes. The included rubber seal helps complete the thermostat-to-housing seal on applications that use this style of installation.

This part cross-references Febi-Bilstein 30680 for the same application. Motorad 306-180 is a practical choice for drivers servicing a Ford Focus thermostat, Ford Escort thermostat, Ford Ranger thermostat, Mazda B2500 thermostat, or Mercury Tracer thermostat with the listed fitment.

Common Problems It Can Address

• Engine running cooler or warmer than the specified thermostat temperature
• Delayed coolant circulation after cold start
• Temperature fluctuation caused by a worn thermostat element
• Coolant seepage at the thermostat seal interface
• Cooling-system service on vehicles requiring a 180F thermostat

Installation Notes and Tips

• Verify the thermostat temperature rating and housing style before installation.
• Inspect the mating surface and coolant passages for corrosion or debris.
• Replace coolant as needed during thermostat service and bleed air from the system after installation.
• Confirm the seal is seated correctly before tightening the housing.
• Use the vehicle service procedure for the specific Ford, Mazda, or Mercury application.
