Thermostat Housing
Cummins®

The Cummins Thermostat Housing, part number 2874817, is designed to play a role in the engine cooling system of commercial trucks. Its purpose is to house the thermostat, which regulates the flow of coolant through the engine, ensuring that the engine operates within optimal temperature ranges. This part is significant for maintaining the efficiency and reliability of the engine cooling system.

Basic Concepts of Thermostat Housing

Thermostat housings are integral to the function of an engine’s cooling system. They serve as a protective enclosure for the thermostat, which controls the flow of coolant based on the engine’s temperature. When the engine is cold, the thermostat remains closed, preventing coolant flow and allowing the engine to warm up quickly. As the engine temperature rises, the thermostat opens, allowing coolant to circulate through the engine and radiator, thereby regulating temperature and preventing overheating ¹.

Role of Part 2874817 Thermostat Housing in Engine Systems

The thermostat housing, identified by part number 2874817, is an integral component in the thermostat arrangement of an engine system. This housing encases the thermostat, which is responsible for regulating the flow of coolant between the engine and the radiator.

When the engine is cold, the thermostat remains closed, preventing coolant from flowing to the radiator. This allows the engine to reach its optimal operating temperature more quickly. Once the engine warms up, the thermostat opens, allowing coolant to circulate through the radiator, where it is cooled before returning to the engine.

The thermostat housing is connected to the engine block via gaskets and bolts, ensuring a secure and leak-free seal. It also interfaces with the upper radiator hose, which carries coolant to the radiator. Additionally, the housing may include provisions for temperature sensors, which monitor the coolant temperature and send data to the engine control unit (ECU).

In summary, the thermostat housing (part 2874817) plays a significant role in maintaining the engine’s temperature by housing the thermostat and facilitating the connection between the engine block, upper radiator hose, and temperature sensors ⁹.

Conclusion

The Thermostat Housing 2874817 by Cummins is a critical component in the engine cooling system of commercial trucks. Its role in housing the thermostat and regulating coolant flow ensures that the engine operates within optimal temperature ranges, contributing to engine efficiency and longevity. The robust design and compatibility with various Cummins engine models make this part a reliable choice for maintaining the performance and reliability of commercial truck engines.
