Cummins®

The 4940625 Water Inlet Connection, a component manufactured by Cummins, is integral to the operation of heavy-duty trucks, particularly within the engine cooling system. Cummins is renowned for its high-quality engine components, and this part is no exception, offering reliable performance and durability ¹.

Basic Concepts of Water Inlet Connection

A Water Inlet Connection serves as a conduit for coolant to enter the engine block. Its function within the engine cooling system is to facilitate the circulation of coolant, which plays a role in maintaining optimal engine temperature. By ensuring that the engine does not overheat, the Water Inlet Connection contributes to the overall efficiency and longevity of the engine ².

Purpose of the 4940625 Water Inlet Connection

The 4940625 Water Inlet Connection is designed to allow coolant to flow into the engine block, where it absorbs heat. This coolant then circulates through the engine, cooling critical components before returning to the radiator to release the absorbed heat. The efficient operation of this part is fundamental to maintaining engine performance and preventing overheating ³.

Key Features

This Cummins part is constructed with durability and performance in mind. It is made from high-quality materials that resist corrosion and wear, ensuring long-term reliability. The design includes precise connection types that ensure a secure fit within the engine system. Additionally, unique attributes such as reinforced seals may be incorporated to enhance performance and prevent leaks.

Benefits

Utilizing the 4940625 Water Inlet Connection offers several advantages. Its design contributes to improved cooling efficiency, which is vital for heavy-duty applications where engines operate under significant stress. The durability of the connection ensures it can withstand the rigors of heavy-duty use, while its reliability reduces the likelihood of unexpected failures.

Installation Process

Installing the 4940625 Water Inlet Connection requires careful attention to detail to ensure a secure and effective fit. Preparatory steps include cleaning the installation area and inspecting the connection for any damage. Tools required may include wrenches and sealants. Following the manufacturer’s guidelines for torque specifications and connection procedures is recommended to achieve the best results.

Troubleshooting Common Issues

Common problems associated with Water Inlet Connections include leaks and blockages. Leaks may occur due to worn seals or improper installation, while blockages can result from debris within the cooling system. Troubleshooting steps involve inspecting the connection for signs of wear or damage, ensuring seals are intact, and checking for debris within the system.

Maintenance Tips

Regular maintenance of the 4940625 Water Inlet Connection is key to ensuring its longevity and efficient operation. This includes periodic inspections for signs of wear or corrosion, and cleaning the connection as part of routine engine maintenance. Adhering to recommended inspection intervals and employing proper cleaning procedures can help prevent issues and ensure optimal performance.

Role of Part 4940625 Water Inlet Connection in Engine Systems

The water inlet connection, identified by part number 4940625, serves as a pivotal interface within engine systems, facilitating the entry of coolant into the engine block. This component is integral to maintaining optimal engine temperature by ensuring a consistent flow of coolant.

When coolant enters through the water inlet connection, it circulates through the engine block, absorbing heat generated by combustion. The heated coolant then travels to the radiator, where it releases heat and cools before re-entering the engine. This continuous cycle is essential for preventing overheating and ensuring efficient engine performance.

The water inlet connection interfaces with several key components within the engine system. It connects to the engine block, allowing coolant to flow into the water jackets—channels designed to surround the cylinders and other heat-generating parts. Additionally, it links to the thermostat housing, which regulates the flow of coolant based on engine temperature.

Furthermore, the water inlet connection is often connected to the lower radiator hose, enabling the return flow of coolant to the radiator. This setup ensures a closed-loop system where coolant is continuously recirculated, enhancing thermal management.

Conclusion

In summary, the water inlet connection (part 4940625) plays a significant role in the thermal regulation of engine systems by providing a vital pathway for coolant entry and circulation. Its integration with the engine block, thermostat housing, and radiator hose underscores its importance in maintaining engine efficiency and longevity.
