DESCRIPTION

The Cummins 3924473 Thermostat Housing is a component designed for use in commercial trucks. Its purpose is to house the thermostat within the engine cooling system, ensuring that the engine operates within optimal temperature ranges. This part is significant for maintaining the efficiency and reliability of truck engines, contributing to their overall performance and longevity.

Basic Concepts of Thermostat Housing

A thermostat housing is a part of the engine cooling system that encloses the thermostat. Its function is to provide a secure environment for the thermostat, allowing it to regulate the flow of coolant based on engine temperature. The housing interacts with other components such as the thermostat and coolant passages, facilitating the circulation of coolant to maintain engine temperature within specified limits 1.

Role of the 3924473 Thermostat Housing in Truck Operation

This Cummins part plays a role in maintaining optimal engine temperature by securely housing the thermostat. This ensures that the engine reaches its operating temperature efficiently and remains within the desired temperature range during operation. By regulating coolant flow, it helps prevent overheating, which can lead to engine damage, and ensures that the engine operates at peak efficiency 2.

Key Features of the 3924473 Thermostat Housing

The design and construction of this part include features that enhance its functionality and durability. It is made from materials that can withstand the high temperatures and pressures of the engine cooling system. The housing incorporates sealing mechanisms to prevent coolant leaks, ensuring a secure fit and effective operation within the engine system. Its unique attributes are tailored to meet the demands of commercial truck applications 3.

Compatibility with Cummins Engines

The Thermostat Housing part 3924473, manufactured by Cummins, is designed to fit seamlessly with a variety of Cummins engines. This part is crucial for maintaining the engine’s optimal operating temperature by regulating the flow of coolant. Here’s how it aligns with the specified engines:

  • 4B3.9 and QSB3.9 30 CM550: These engines, both part of the Cummins B Series, share a similar design in their cooling systems, making the Thermostat Housing part 3924473 compatible with both.

  • 6B5.9 and ISB5.9G CM2180: These engines, belonging to the Cummins B and ISB Series respectively, also feature a compatible design for the Thermostat Housing part 3924473. The part’s fitment ensures efficient coolant flow, which is essential for these engines’ performance.

  • B4.5, B5.9 G, B5.9 GAS PLUS CM556, QSB5.9 30 CM550, and QSB5.9G: These engines, while part of different series, share a commonality in their cooling system architecture. The Thermostat Housing part 3924473 is engineered to fit these engines, ensuring that the coolant flow is regulated effectively, which is vital for maintaining the engine’s temperature and overall efficiency.

The compatibility of the Thermostat Housing part 3924473 across these engines underscores Cummins’ commitment to providing parts that are versatile and reliable, ensuring that maintenance and repair processes are straightforward and efficient.

Role of Part 3924473 Thermostat Housing in Engine Systems

The thermostat housing, identified by part number 3924473, is an integral component in the thermal management system of an engine. It serves as the enclosure for the thermostat, which regulates the flow of coolant through the engine.

When the engine is cold, the thermostat remains closed, directing coolant through the coolant bypass kit. This kit allows coolant to circulate within the engine block without passing through the radiator, helping the engine reach optimal operating temperature more quickly.

As the engine warms up, the thermostat gradually opens, allowing coolant to flow into the radiator where it is cooled before returning to the engine. The thermostat housing ensures a secure fit for the thermostat and provides a pathway for coolant to enter and exit the housing.

In summary, the thermostat housing (part 3924473) works in conjunction with the thermostat and coolant bypass kit to maintain engine temperature, ensuring efficient operation and longevity of the engine components.

Conclusion

The Cummins 3924473 Thermostat Housing is a vital component in the engine cooling system of commercial trucks. Its role in maintaining optimal engine temperature, combined with its durable construction and compatibility with various Cummins engines, makes it an essential part for ensuring engine efficiency and longevity. Regular maintenance and proper installation are key to maximizing the benefits of this part.
