Product Specification

WESPC 4133L027 Thermostat Housing for Perkins 1004 1004.4 1104 1106 Engines

Application:

WESPC 4133L027 thermostat housing is designed for Perkins 1000 series 4- and 6-cylinder diesel engines, including models 1004.40, 1004.40T, 1004.42, and 1006.60. This housing serves as the mounting interface for the engine’s thermostat, ensuring secure placement and uninterrupted coolant flow between the cylinder head and radiator. It plays a critical role in maintaining the integrity of the cooling system by channeling coolant through the thermostat and regulating engine temperature. The housing is engineered to withstand thermal expansion, vibration, and mechanical stress, supporting long-term reliability in high-output diesel platforms. It is interchangeable with part number 4133L054 and verified for use in both vertical and side-mounted configurations depending on engine layout.

Generator sets:

Commonly installed in 100–250 kVA diesel generator platforms powered by Perkins 1004 and 1006 series engines. The WESPC 4133L027 thermostat housing ensures leak-free 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 4133L027 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.

Industrial systems:

Installed in stationary pumps, compressors, and hydraulic power units using Perkins 1000 series engines. The thermostat housing supports continuous operation by maintaining coolant flow and sealing integrity. Its robust design ensures performance in demanding industrial environments with frequent start-stop cycles and elevated ambient temperatures.
