Water Transfer Tube
Cummins®

The Cummins 4956502 Water Transfer Tube is a component designed for use in the cooling systems of heavy-duty trucks. Its purpose is to facilitate the efficient transfer of coolant between the engine and the radiator, ensuring that the engine operates within optimal temperature ranges. This component is integral to maintaining the performance and longevity of the engine by playing a role in the cooling system through effective coolant circulation ¹.

Function and Operation

This Cummins part operates within the engine cooling system by providing a conduit for coolant to travel from the engine to the radiator and back. This transfer is vital for dissipating heat generated by the engine. As the engine runs, it produces a significant amount of heat. The coolant absorbs this heat as it circulates through the engine block and cylinder heads. The heated coolant then flows through the Water Transfer Tube to the radiator, where it releases heat into the air, cooling down before returning to the engine to repeat the process. This continuous cycle helps maintain the engine’s temperature within a specified range, optimizing performance and preventing overheating ².

Key Features

The 4956502 is constructed with durability and efficiency in mind. It is made from high-quality materials that are resistant to corrosion and high temperatures, ensuring longevity and reliable performance. The design includes precise connection types that ensure a secure fit within the cooling system, minimizing the risk of leaks. Additionally, the tube may feature unique attributes such as reinforced sections or specialized coatings that enhance its performance and durability in demanding operating conditions ³.

Benefits

The Water Transfer Tube offers several advantages. It provides improved coolant flow, which enhances the efficiency of the cooling system. This results in better engine protection against overheating, especially under heavy loads or in high-temperature environments. The tube’s robust construction and design contribute to increased reliability, ensuring that the cooling system operates effectively over the long term. These benefits collectively contribute to the overall performance and durability of the engine ⁴.

Installation Considerations

When installing the 4956502, it is important to follow guidelines and best practices to ensure optimal performance and longevity.
