Thermostat 2485C036, 4224639M1 Perkins

The Perkins 2485C036 / 4224639M1 Thermostat is a genuine AGCO cooling system component designed to regulate coolant circulation and maintain stable operating temperature in Perkins 1000 Series diesel engines. Engineered to OEM specifications, this thermostat helps the engine warm up quickly during cold starts while preventing overheating under heavy-duty operating conditions. Using a precision-calibrated wax-pellet mechanism, the thermostat automatically controls coolant flow between the engine and radiator based on temperature demand. During startup, coolant circulation remains restricted to help the engine reach optimal operating temperature faster, improving combustion efficiency, fuel economy, and overall engine performance. As coolant temperature increases, the thermostat gradually opens to allow full coolant flow through the radiator system. Manufactured from high-quality stainless steel, brass, and heat-resistant internal components, the Perkins 2485C036 thermostat is built to withstand continuous thermal cycling, vibration, coolant pressure, and demanding agricultural or industrial environments. Its durable construction and accurate opening characteristics help protect critical engine components against excessive thermal stress, overheating, and premature wear. Designed for reliable fitment and long service life, this original AGCO thermostat is commonly used in agricultural tractors, construction equipment, generators, and industrial machinery powered by Perkins 1000 Series engines.
