Water Bypass Tube (Part 213485) Compatibility with Cummins Engines

The Water Bypass Tube, identified by part number 213485, is a component in the cooling system of several Cummins engines. This part is designed to manage the flow of coolant, ensuring optimal engine temperature regulation. Below is a detailed overview of the engines with which this part is compatible.

G855 Series

The G855 engine series, including variants such as G855 CM558 and GTA855 CM558 (CM2358), utilizes the Water Bypass Tube to maintain efficient coolant circulation. This series is known for its robust design and high performance, making it suitable for heavy-duty applications.

N14 Series

The N14 engine series, which includes both N14 G and N14 MECHANICAL variants, also incorporates the Water Bypass Tube. This part is essential in managing the coolant flow in these engines, contributing to their durability and reliability in demanding conditions.

NH/NT 855 Series

The NH/NT 855 engine series benefits from the Water Bypass Tube to ensure effective coolant management. This series is designed for applications requiring high power output and reliability, making the Water Bypass Tube a crucial component in maintaining engine efficiency.

G101 Series

The G101 engine, while distinct from the other series, also utilizes the Water Bypass Tube. This part plays a vital role in the cooling system of the G101, ensuring that the engine operates within its optimal temperature range.

Role of Part 213485 Water Bypass Tube in Engine Systems

The 213485 Water Bypass Tube is an integral component in the thermal management system of various engine setups. It facilitates the controlled flow of coolant, ensuring optimal engine temperature is maintained under varying operational conditions.

Interaction with Base Parts and Connections

In conjunction with the base parts and connections, the Water Bypass Tube allows for a secondary coolant pathway. This is particularly important when the primary coolant flow through the thermostat is restricted, such as when the thermostat is closed. The bypass tube ensures that a portion of the coolant continues to circulate, preventing overheating and maintaining consistent engine temperature.

Coordination with Water Outlet and Thermostat Housing

The Water Bypass Tube interfaces directly with the water outlet and thermostat housing. When the thermostat is closed, the bypass tube directs coolant from the water pump back into the engine block or directly to the water manifold, bypassing the radiator. This helps in warming up the engine more quickly during cold starts and maintains a stable operating temperature once the engine reaches its optimal working range.

Integration with Manifold and Water Manifolds

In systems where manifold water distribution is utilized, the Water Bypass Tube plays a significant role. It ensures that coolant is efficiently distributed across the manifold, aiding in the uniform heating of the engine components. This is especially important in high-performance engines where precise temperature control is necessary for optimal efficiency and longevity.

Relationship with Thermostat and Thermostat Housing Mounting

The effectiveness of the Water Bypass Tube is closely tied to the operation of the thermostat and its housing. When the thermostat opens, allowing coolant to flow through the radiator, the bypass tube’s role diminishes. However, during periods when the thermostat is closed, the bypass tube becomes the primary pathway for coolant circulation, ensuring that the engine does not overheat.

Function in Water Pump and Manifold Systems

In systems where the water pump and manifold are integral, the Water Bypass Tube ensures that coolant circulation is not entirely dependent on the thermostat’s state. This redundancy is vital for maintaining engine health, as it prevents scenarios where the engine could overheat due to thermostat failure or malfunction.

Role in Water Outlet Tube and Connection

The Water Bypass Tube also works in tandem with the water outlet tube and its connection points. It provides an alternative route for coolant when the primary outlet is obstructed or when additional cooling is required. This ensures that the engine’s cooling system remains robust and reliable under a variety of operating conditions.

Conclusion

The Cummins 213485 Water Bypass Tube is a key component in the intricate dance of coolant flow within an engine’s thermal management system. Its role in providing an alternative coolant pathway ensures engine stability and longevity, making it an essential part of modern engine designs.
