Thermostat Housing Support
Cummins®

The Thermostat Housing Support, part number 3076794, manufactured by Cummins, is a component designed to play a role in the engine cooling system of heavy-duty trucks. Its primary function is to provide structural support and facilitate the operation of the thermostat, ensuring efficient engine temperature management ¹.

Function and Operation

The Thermostat Housing Support operates within the engine cooling system by housing the thermostat and connecting to the coolant passages and engine block. It allows for the controlled flow of coolant based on the engine’s temperature, which is regulated by the thermostat. When the engine is cold, the thermostat remains closed, restricting coolant flow and allowing the engine to warm up quickly. As the engine temperature rises, the thermostat opens, permitting coolant to circulate through the engine block, radiator, and other components to maintain optimal operating temperature ².

Key Features

This Cummins part is constructed from durable materials, typically a combination of metal and high-strength polymers, ensuring resilience under high-temperature and high-pressure conditions. Its design includes precise fittings and seals to ensure a secure connection to the engine block and coolant passages. Additionally, the housing is engineered to withstand thermal expansion and contraction, maintaining integrity over the engine’s lifespan ³.

Role in Truck Operation

In the operation of a heavy-duty truck, the Thermostat Housing Support plays a role by ensuring the engine maintains an optimal temperature. This is achieved through the regulated flow of coolant, which prevents overheating and enhances engine efficiency. Proper temperature management contributes to the longevity of engine components, reduces the risk of thermal stress, and ensures consistent performance under varying load conditions.

Benefits

Using this part offers several benefits. It contributes to improved engine performance by ensuring consistent and efficient coolant flow. The durable construction enhances the component’s longevity, reducing the need for frequent replacements. Additionally, its reliable operation under various operating conditions supports the overall reliability and efficiency of the truck’s engine.

Installation and Compatibility

For proper installation of the Thermostat Housing Support, it is important to follow manufacturer guidelines to ensure a secure and correct fit. Compatibility with various Cummins engine models should be verified to ensure optimal performance. Specific requirements may include torque specifications for fastening and the use of recommended gaskets and seals to prevent leaks.

Maintenance and Troubleshooting

Routine maintenance practices for the Thermostat Housing Support include regular inspections for signs of wear, corrosion, or leaks. Ensuring that all connections are tight and that the thermostat operates correctly is vital for continued efficient engine cooling. Common troubleshooting tips involve checking for coolant leaks, verifying thermostat operation, and inspecting the housing for any damage or deformation.

Thermostat Housing Support for Cummins Engines

The Thermostat Housing Support, part number 3076794, manufactured by Cummins, is a critical component in the engine systems of the M11 CELECT PLUS and M11 MECHANICAL engines. This part is designed to provide structural integrity and support to the thermostat housing, ensuring that it remains securely in place and functions optimally.

M11 CELECT PLUS Engine

In the M11 CELECT PLUS engine, the Thermostat Housing Support is integral to maintaining the engine’s thermal efficiency. The CELECT PLUS variant is equipped with advanced electronic controls that manage engine performance and emissions. The support part ensures that the thermostat housing, which regulates the engine’s coolant flow, is properly aligned and does not shift during operation. This stability is crucial for the precise temperature management required by the CELECT PLUS system.

M11 MECHANICAL Engine

For the M11 MECHANICAL engine, the Thermostat Housing Support plays a similar role but is tailored to the mechanical control systems of this engine. The MECHANICAL variant relies on traditional mechanical components for its operation. The support part here is essential for maintaining the alignment and stability of the thermostat housing, which is vital for the engine’s overall performance and longevity. It ensures that the housing can withstand the mechanical stresses and vibrations inherent in the engine’s operation.

Both engines benefit from the robust design of the Thermostat Housing Support, which is engineered to provide long-lasting durability and reliability. This part is a testament to Cummins’ commitment to quality and precision in engine components, ensuring that the thermostat housing remains securely in place, regardless of the engine variant.

Role of Part 3076794 Thermostat Housing Support in Engine Systems

The thermostat housing support, identified by part number 3076794, is an integral component in the assembly and functionality of the engine’s cooling system. This part securely mounts the thermostat housing to the engine block, ensuring a stable and leak-free connection.

When the engine is operational, the thermostat housing support facilitates the circulation of coolant by maintaining the structural integrity of the housing. It allows the thermostat to regulate the flow of coolant based on the engine’s temperature, ensuring optimal operating conditions.

Moreover, the support plays a role in sealing the housing to prevent coolant leaks, which could lead to engine overheating and potential damage. It also aids in the efficient transfer of heat from the engine to the coolant, enhancing the overall cooling efficiency of the system.

Conclusion

In summary, the thermostat housing support is essential for the proper function of the thermostat and the maintenance of the engine’s thermal management system. Its robust design and reliable operation contribute to the overall efficiency and longevity of the engine, making it a critical component in the cooling system of heavy-duty trucks.
