WESPC 2485C041 Thermostat for Perkins 1103 1104 MF Valmet Valtra Tractor

WESPC 2485C041 Thermostat for Perkins 1103 1104 MF Valmet Valtra Tractor

Application:

WESPC 2485C041 thermostat assembly is designed for Perkins 1100 series 3- and 4-cylinder diesel engines, including models 1103A-33T, 1103A-33TG1, 1104C-44, and 1104C-44T. These engines are widely used in agricultural tractors, construction machinery, generator sets, and industrial systems requiring precise thermal regulation. The thermostat assembly includes the thermostat, connection housing, and sealing components, ensuring complete compatibility and optimal coolant flow control. It begins to open at 82°C (180°F), helping the engine reach operating temperature quickly and maintaining thermal stability during continuous operation. This assembly has been superseded by part numbers 4133L507, 4133L508, and 4133L509, depending on installation orientation.

Generator sets:

Commonly installed in 50–150 kVA diesel generator platforms powered by Perkins 1103 and 1104 series engines. The WESPC 2485C041 thermostat assembly ensures consistent coolant circulation, preventing overheating and supporting fuel efficiency. It contributes to stable combustion and reduced wear in commercial backup systems, telecom power modules, and mobile gensets operating under variable load conditions.

Construction machinery:

Suitable for JCB, Terex, and Volvo CE equipment powered by Perkins 1100 series engines. The thermostat assembly maintains optimal engine temperature in high-vibration environments, supporting torque output and mechanical reliability. Verified applications include JCB 3CX, Terex TLB840, and Volvo BL60 loaders, where thermal control is essential to uptime and engine longevity.

Agricultural equipment:

Applied in Massey Ferguson and Landini tractors requiring long service intervals and stable engine operation. The WESPC 2485C041 thermostat assembly supports rapid warm-up and consistent temperature regulation during extended field operations, reducing fuel consumption and protecting internal components from thermal cycling. It ensures reliable performance in MF 440, MF 470, and Landini Powerfarm series tractors equipped with Perkins 1104C engines.

Industrial systems:

Installed in stationary pumps, compressors, and hydraulic power units using Perkins 1100 series engines. The thermostat assembly supports continuous operation by regulating coolant flow and maintaining lubrication integrity. Its robust design ensures performance in demanding industrial environments with frequent start-stop cycles and elevated ambient temperatures.
