Role of Part 4992623 in Engine Systems

This part is an essential component in the cooling system of an engine. It facilitates the connection between the water outlet and other critical components, ensuring efficient coolant flow throughout the system.

Integration with Engine Components

1. Water Pump Connection: The Water Outlet Connector interfaces directly with the water pump, allowing coolant to be circulated from the pump to the engine block. This connection is vital for maintaining consistent coolant flow, which is necessary for effective heat dissipation.

2. Thermostat Housing: The connector is often part of the thermostat housing assembly. It ensures a secure seal, preventing coolant leaks and maintaining the integrity of the cooling system. This is important for the thermostat to function correctly, regulating the engine’s temperature.

3. Radiator Connection: The Water Outlet Connector links the engine to the radiator, enabling coolant to travel from the engine to the radiator for cooling. This continuous circulation helps in dissipating heat absorbed by the coolant as it passes through the engine block.

4. Heater Core: In systems where the engine provides heat for the vehicle’s interior, the connector plays a role in directing coolant to the heater core. This ensures that the cabin can be warmed efficiently during cold weather.

5. Coolant Reservoir: The connector may also be involved in the connection to the coolant reservoir. This allows for the expansion and contraction of coolant as it heats up and cools down, maintaining pressure within the system and preventing overflow or vacuum issues.

6. Engine Block Passages: Within the engine block, the Water Outlet Connector ensures that coolant reaches all necessary passages. This includes areas around the cylinders, where heat generation is highest, ensuring these critical components remain within optimal temperature ranges.

By understanding the role of the Water Outlet Connector in these various connections, engineers and mechanics can better appreciate its importance in maintaining the overall health and efficiency of the engine’s cooling system ³.

Conclusion

The Water Outlet Connector 4992623 by Cummins is a critical component in the cooling system of commercial trucks, ensuring efficient coolant flow and temperature regulation. Its robust design, compatibility with various Cummins engines, and integration with key engine components highlight its importance in maintaining engine performance and longevity.
