Motorad 383-205 Engine Coolant Thermostat

Heavy Duty Thermostat for Ford Cooling Systems

The Motorad Heavy Duty Thermostat 383-205 is an engine coolant thermostat built for demanding cooling-system service. It is specified at 205 degrees F and uses OEM-style materials and sealing features to support stable coolant temperature control in Ford truck and van applications.

Compatible With 1994-1995 Ford F-250, 1994-1995 Ford F-350, and 1995 Ford E-350 Econoline and E-350 Econoline Club Wagon, this thermostat is a direct-fit cooling service part for OE-specified temperature control. The Motorad 383-205 is also a practical replacement choice when servicing a Ford F-250 thermostat or Ford F-350 thermostat application that calls for a 205F unit.

Product Details

Motorad Heavy Duty Thermostat 383-205 is manufactured to OE specifications using OEM-quality materials and safety standards. The copper case and wax compound help the thermostat react quickly as coolant temperature changes, while the offset design and air relief valve support proper coolant flow and system bleeding. This part cross-references Carlson 14252 for the same application.

What It Helps Address

• Engine running cooler or hotter than the OE temperature target
• Delayed coolant temperature regulation after startup
• Cooling-system service on Ford E-350 Econoline and E-350 Econoline Club Wagon models
• Thermostat replacement on 1994-1995 Ford F-250 and F-350 trucks
• Air trapped in the cooling system after thermostat service

Installation Notes and Tips

Verify the OE-specified 205F temperature before installation. Confirm sealing flange diameter, bypass dimensions, and gasket/seal condition during service. Clean the housing mating surfaces thoroughly, install the included rubber seal, and orient the thermostat correctly so the air relief feature can function as intended.

Quality Assurance

Motorad manufactures this thermostat as an OE-supplier part using OEM-quality materials and processes. The design follows factory-style specifications for fit and temperature control in the listed Ford applications.
