Compatibility with Cummins Engines

The Thermostat Housing part number 3013611, manufactured by Cummins, is designed to fit seamlessly with several Cummins engine models. This part is integral in regulating the engine’s temperature by controlling the flow of coolant. Here is a detailed look at the compatibility of this thermostat housing with various Cummins engines:

NH/NT 855 Engines

The Thermostat Housing 3013611 is specifically engineered to fit the NH/NT 855 series engines. These engines are known for their robust performance and reliability, often used in heavy-duty applications such as construction equipment and agricultural machinery. The precise fit ensures efficient coolant flow, which is crucial for maintaining optimal engine temperature and preventing overheating.

Grouping by Application

While the Thermostat Housing 3013611 is primarily associated with the NH/NT 855 engines, it is also compatible with other Cummins engines within the same family. This grouping is based on similar design parameters and engineering requirements, ensuring that the housing fits snugly and functions effectively across different engine models.

Importance of Compatibility

Ensuring that the Thermostat Housing 3013611 is correctly matched with the appropriate engine model is vital for maintaining engine performance and longevity. An improperly fitted housing can lead to coolant leaks, engine overheating, and ultimately, engine damage. Cummins has designed this part to meet the stringent requirements of their engines, providing a reliable and durable solution for temperature regulation.

Role of Thermostat Housing in Engine Systems

The thermostat housing, identified by part number 3013611, 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 to the engine based on its temperature.

When the engine is cold, the thermostat remains closed, preventing coolant from flowing through 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 engine and radiator, maintaining a consistent temperature.

The thermostat housing is connected to several key components within the engine system. It is typically bolted to the engine block or cylinder head, providing a secure mount for the thermostat. The housing also connects to the upper radiator hose, which carries coolant from the thermostat to the radiator. Additionally, it may be linked to the coolant temperature sensor, which monitors the temperature of the coolant and sends data to the engine control unit (ECU).

In some engine designs, the thermostat housing may also incorporate the coolant outlet pipe, directing coolant flow to various parts of the engine, such as the heater core or other cooling passages. This ensures efficient distribution of coolant throughout the engine, enhancing its performance and longevity.

The housing is designed to withstand the pressures and temperatures of the cooling system, ensuring a reliable seal around the thermostat and preventing coolant leaks. Its role in maintaining the engine’s thermal equilibrium is essential for optimal engine performance, fuel efficiency, and emissions control.

Conclusion

The Cummins 3013611 Thermostat Housing plays a crucial role in the engine cooling system by regulating coolant flow and maintaining optimal engine temperature. Its design and materials ensure durability and efficient performance, contributing to the longevity and reliability of heavy-duty engines. Proper installation, regular maintenance, and ensuring compatibility with specific engine models are key to maximizing the benefits of this component.
