Role of Part 2870351 Flexible Hose in Engine Systems

Part 2870351 Flexible Hose is a component in various engine systems, facilitating the transfer of fluids and ensuring the smooth operation of several critical functions.

In drain systems, the Flexible Hose allows for the efficient removal of waste fluids, such as coolant or oil, from the engine. This is particularly important during maintenance procedures where old fluids need to be replaced to ensure optimal engine performance and longevity.

For remote oil systems, the Flexible Hose provides a reliable connection between the oil reservoir and the engine. This setup is often used in high-performance or custom engine builds where the oil reservoir is located away from the engine block. The hose ensures that oil is consistently supplied to the engine, maintaining proper lubrication and cooling.

In conjunction with an Oil Drain Valve, the Flexible Hose plays a key role in facilitating the drainage of oil from the engine. This is vital during oil changes, as it allows for the complete removal of old oil, preventing contamination and ensuring that fresh oil can be introduced without mixing with residual old oil.

Within plumbing systems, the Flexible Hose is used to connect various components, such as filters, pumps, and reservoirs. Its flexibility allows for easier installation and maintenance, reducing the risk of leaks and ensuring a secure connection between rigid components.

In fuel system primers, the Flexible Hose is utilized to create a sealed pathway for fuel to travel from the primer bulb to the fuel lines. This is essential for ensuring that the fuel system is properly primed, allowing for easier engine start-up and consistent fuel delivery to the engine.

Overall, Part 2870351 Flexible Hose is a versatile and indispensable component in various engine systems, contributing to the efficient transfer of fluids and the reliable operation of engine components.

Conclusion

The Cummins 2870351 Flexible Hose is a critical component in the operation of commercial trucks, facilitating the transfer of fluids between various systems.
