This part is engineered to meet the specific needs of the QSK19, CM2350, and K105 engines, providing a critical connection in the engine’s system.

QSK19 and CM2350 Engines

For the QSK19 and CM2350 engines, the 4080863 Flexible Hose is a vital component that facilitates the transfer of fluids or gases between various engine parts. Its flexibility allows for smooth operation even under varying engine conditions, reducing the risk of leaks and ensuring consistent performance. This hose is particularly important in maintaining the integrity of the engine’s cooling system, fuel delivery system, or exhaust system, depending on its specific application within the engine.

K105 Engine

In the K105 engine, the 4080863 Flexible Hose serves a similar purpose, providing a durable and reliable connection that can withstand the rigors of heavy-duty operations. Its design ensures that it can handle the high pressures and temperatures typical of this engine model, contributing to the overall efficiency and longevity of the engine.

Grouping for Efficiency

When considering the QSK19 and CM2350 engines together, it is evident that the 4080863 Flexible Hose is engineered to fit both models due to their shared design principles and operational requirements. This commonality allows for easier maintenance and part replacement, as the same hose can be used across multiple engine types, simplifying inventory management and reducing downtime.

The K105 engine, while distinct in its design and application, also benefits from the use of the 4080863 Flexible Hose. Its robust construction and flexibility make it an ideal choice for the demanding conditions encountered in this engine model, ensuring that it can perform reliably under extreme stress.

Role of Part 4080863 Flexible Hose in Engine Systems

The part 4080863 Flexible Hose is an essential component in various engine systems, facilitating the smooth operation of several key elements.

Interaction with Housing

In engine systems, the flexible hose connects to the housing, which often encases sensitive components such as sensors or fluid reservoirs. The hose’s flexibility allows it to accommodate the slight movements and vibrations that occur during engine operation, ensuring a secure and leak-free connection. This is particularly important in systems where precise fluid dynamics are required, such as in fuel injection systems or hydraulic controls ².

Collaboration with Thermostat

The flexible hose also plays a significant role when integrated with the thermostat housing. The thermostat regulates the engine’s temperature by controlling the flow of coolant. The hose connects the thermostat housing to the radiator or other cooling system components, allowing coolant to circulate efficiently. Its flexibility ensures that thermal expansion and contraction do not stress the connections, maintaining the integrity of the cooling system and preventing leaks that could lead to overheating.

Additional System Integrations

Beyond housing and thermostat applications, the flexible hose is utilized in various other engine systems. For instance, in emissions control systems, it connects components like the EGR (Exhaust Gas Recirculation) valve to the intake manifold, allowing recirculated exhaust gases to mix with the intake air. In brake systems, it may connect the brake fluid reservoir to the master cylinder, ensuring consistent brake fluid pressure.

The versatile nature of the 4080863 Flexible Hose makes it a valuable component in ensuring the reliable operation of multiple engine systems, contributing to overall vehicle performance and durability.
