WESPC 4133L032 Thermostat Assembly for Perkins 1004 1006 Engine Excavator Parts

Application:

WESPC 4133L032 thermostat housing assembly is designed for Perkins 1000 series 4- and 6-cylinder diesel engines, including models 1004.40, 1004.42, 1006.60, and 1006.60T. This component serves as the mounting and connection point for the engine’s thermostat, ensuring proper coolant flow between the cylinder head and radiator. It supports precise thermal regulation by housing the thermostat securely and maintaining coolant channel integrity. The assembly is essential for maintaining optimal engine temperature, preventing overheating, and supporting long-term reliability in high-output diesel platforms. It is commonly paired with thermostats such as 2485C036 and 2485C041 depending on engine configuration.

Generator sets:

Installed in 100–250 kVA diesel generator platforms powered by Perkins 1004 and 1006 series engines. The WESPC 4133L032 thermostat housing ensures stable coolant routing and secure thermostat positioning, contributing to consistent combustion and reduced thermal stress. It supports efficient heat dissipation and long-term operation in commercial standby and prime power systems, including telecom, industrial, and agricultural gensets.

Construction machinery:

Suitable for JCB, Massey Ferguson, and Volvo CE equipment powered by Perkins Phaser and 1000 series engines. The thermostat housing maintains coolant channel integrity in high-vibration environments, supporting torque output and mechanical reliability. Verified applications include JCB 3CX, Massey Ferguson 390T, and Volvo BL60 loaders, where thermal control is essential to uptime and engine longevity.

Agricultural equipment:

Used in tractors and harvesters requiring high torque and extended service intervals. The WESPC 4133L032 thermostat housing supports consistent temperature regulation during long 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 1004.40 and 1006.60 engines.
