Water Transfer Tube
Cummins®

The Water Transfer Tube (Part #5262364) manufactured by Cummins is a component designed to facilitate the efficient transfer of coolant within the cooling system of heavy-duty trucks. Its purpose is to ensure that the engine maintains optimal operating temperatures, thereby contributing to the overall performance and longevity of the vehicle ¹.

Basic Concepts of Water Transfer Tubes

A water transfer tube is a conduit that allows coolant to flow between different parts of a truck’s cooling system. It operates on the principle of fluid dynamics, where coolant is circulated to absorb heat from the engine and dissipate it through the radiator. The efficiency of this process is crucial for maintaining engine temperature within safe limits ².

Role and Function in Truck Operation

This Cummins part plays a specific role in the operation of a truck by connecting various components within the cooling system, such as the engine block, radiator, and thermostat housing. It ensures a continuous flow of coolant, which absorbs heat from the engine and transfers it to the radiator for dissipation. This interaction is vital for the stable operation of the truck’s engine under varying load conditions ³.

Key Features

The Water Transfer Tube is characterized by its robust material composition, typically made from durable polymers or metals that can withstand high temperatures and pressures. Its design includes precise fittings and connections to ensure a leak-free seal, enhancing its performance and durability. Additionally, the tube may feature reinforced sections to handle the rigors of heavy-duty truck operation.

Benefits

The use of the 5262364 offers several benefits, including improved cooling efficiency due to its optimized design for coolant flow. This results in more reliable engine temperature management, which can contribute to enhanced engine performance and longevity. The tube’s durable construction also ensures it can withstand the demanding conditions of heavy-duty truck use.

Troubleshooting and Maintenance

Common issues with this part may include leaks, blockages, or degradation over time. Regular inspection for signs of wear, such as cracks or soft spots, is recommended. Maintenance practices should include checking for proper coolant levels and ensuring there are no obstructions in the coolant flow path. Addressing issues promptly can help maintain optimal performance and extend the tube’s service life.

Similarly, the QSB6.7 series engines, specifically the QSB6.7 CM2250 and QSB6.7 CM2350 B105, also integrate the Water Transfer Tube part number 5262364. These engines are typically employed in agricultural and industrial settings, where durability and efficiency are paramount.

In the larger displacement category, the QSC9 CM2250/QSL9 CM2250 and QSL9 CM2250 engines are equipped with this part. These engines are designed for high-performance applications, requiring precise cooling mechanisms to maintain their operational integrity.

Lastly, the QSL9 CM2350 L102 engine also utilizes the Water Transfer Tube part number 5262364. This engine is engineered for demanding environments, ensuring that the cooling system operates effectively under various conditions.

Role of Part 5262364 Water Transfer Tube in Engine Systems

The 5262364 is an essential component in the efficient operation of various engine systems. Its primary function is to facilitate the movement of water between different parts of the engine, ensuring optimal performance and longevity of the engine components.

Integration with Plumbing Systems

In the context of engine plumbing, the Water Transfer Tube plays a significant role in directing water flow. It connects to the water outlet tube, allowing for the regulated transfer of water to and from the engine block. This ensures that the engine maintains the correct temperature, preventing overheating and potential damage.

Interaction with Exhaust Recirculation Water Systems

When integrated into exhaust recirculation water systems, the Water Transfer Tube aids in the cooling process of recirculated exhaust gases. By efficiently transferring water, it helps in reducing the temperature of the exhaust gases before they are reintroduced into the combustion process. This not only enhances engine efficiency but also reduces emissions, contributing to a cleaner operation.

Turbocharger Cooling

In turbocharged engines, the Water Transfer Tube is vital for maintaining the turbocharger’s operational temperature. It ensures that the turbocharger receives a consistent flow of cooling water, which is essential for its longevity and performance. The tube connects to the turbocharger’s water passages, allowing for effective heat dissipation and preventing overheating.

Overall Engine Cooling

Beyond specific components, the Water Transfer Tube is a key element in the overall engine cooling system. It works in conjunction with the water outlet tube to ensure that all engine parts receive adequate cooling. This comprehensive cooling approach is essential for the engine’s durability and efficiency, making the Water Transfer Tube a fundamental component in engine design and maintenance.

Conclusion

The Water Transfer Tube part number 5262364 by Cummins is a critical component in the cooling systems of heavy-duty trucks and various Cummins engines. Its role in facilitating efficient coolant transfer ensures optimal engine performance and longevity.
