Cummins Engine Part 3625259: Water Inlet Connection

The Cummins part 3625259, identified as a Water Inlet Connection, is a critical component in the cooling system of various Cummins engines. This part ensures that coolant flows efficiently into the engine, maintaining optimal operating temperatures and preventing overheating.

Application in Cummins Engines

• V903 Engine Family: The Water Inlet Connection part 3625259 is integral to the V903 engine series. It connects the coolant supply line to the engine block, facilitating the flow of coolant from the radiator to the engine. This connection is important for maintaining the engine’s thermal efficiency and longevity.

• Other Cummins Engines: While the primary focus here is on the V903, part 3625259 is also compatible with other Cummins engine models that share similar design specifications. This compatibility ensures that the part can be used across multiple engine types, providing a standardized solution for coolant inlet connections.

Importance of Proper Installation

Proper installation of the Water Inlet Connection is important to ensure that the coolant flows without obstruction. Any misalignment or improper fitting can lead to leaks, reduced cooling efficiency, and potential engine damage.

Any issues with the Water Inlet Connection should be addressed promptly to prevent coolant loss and maintain engine performance.

Understanding the Role of Part 3625259 Water Inlet Connection in Engine Systems

The water inlet connection, specifically part 3625259, is integral to the efficient operation of various engine systems. This component facilitates the entry of coolant into the engine block, ensuring that the internal components remain within optimal temperature ranges during operation.

Integration with the Cooling System

In the cooling system, the water inlet connection interfaces directly with the engine block and the thermostat housing. It allows coolant to flow from the radiator, through the water pump, and into the engine block. This flow is important for dissipating heat generated by combustion processes. The design of part 3625259 ensures a secure and leak-free connection, which is vital for maintaining the integrity of the cooling system.

Interaction with the Thermostat Housing

The water inlet connection is typically bolted to the thermostat housing. This housing regulates the flow of coolant based on engine temperature. When the engine is cold, the thermostat remains closed, directing coolant back to the pump and preventing it from entering the engine block. As the engine warms, the thermostat opens, allowing coolant to flow through the water inlet connection into the engine block. This regulated flow helps achieve and maintain the engine’s operating temperature.

Connection to the Engine Block

Once coolant enters through the water inlet connection, it circulates through passages within the engine block. These passages are designed to surround critical components such as the cylinders, pistons, and cylinder heads. The coolant absorbs heat from these areas, which is then carried away from the engine block and back to the radiator for dissipation. The effectiveness of this process is highly dependent on the proper function of the water inlet connection.

Role in the Overall Engine System

Beyond the cooling system, the water inlet connection plays a supportive role in the overall engine system. Efficient coolant flow contributes to the longevity of engine components by preventing overheating. It also aids in the stability of combustion processes, which can affect engine performance and fuel efficiency. Additionally, the water inlet connection must be compatible with other system components, such as hoses and clamps, to ensure a cohesive and reliable cooling system.

Conclusion

In summary, the Water Inlet Connection 3625259 is a key component in the engine’s cooling system, facilitating the essential flow of coolant to and from the engine block. Its proper function is necessary for the maintenance of engine temperature, protection of internal components, and overall engine efficiency.
