Coolant Hose 17127568753 For BMW E60

The return pipe of automobile cooling system (also called coolant return pipe) is an important part of the cooling system, and its main function is to adjust the flow and pressure of coolant. If the return pipe fails, the following effects may be caused:

1. Decreased cooling effect: The failure of the return pipe may cause the flow of coolant to be blocked or blocked, thus affecting the normal operation of the cooling system. The coolant can't flow and dissipate heat effectively, which leads to the increase of engine temperature and the decrease of cooling effect. This may lead to engine overheating and even engine failure.

2. Overheating of the engine: The failure of the return pipe may cause the coolant not to flow back to the engine normally, so that the engine cannot get enough cooling. This will cause the engine temperature to rise beyond the normal operating range, and then cause the engine to overheat. Overheated engine may cause serious damage such as cylinder liner rupture and cylinder head deformation, which requires expensive maintenance or replacement.

3. Coolant leakage: Failure of the return pipe may lead to coolant leakage. The return pipe is connected to different parts of the cooling system. If the return pipe is broken, leaking or loose, the coolant may leak out. The leakage of coolant will reduce the amount of coolant in the cooling system, which can not maintain the normal cooling effect, and then lead to overheating and damage of the engine.

4. Bubble blockage: Failure of the return pipe may lead to bubble blockage in the cooling system. The design of the return pipe is helpful to eliminate bubbles in the cooling system and keep the flow of coolant smooth. If the return pipe fails, bubbles may not be discharged smoothly and be blocked in the cooling system. Bubble blockage will affect the circulation of coolant and heat dissipation effect, resulting in an increase in engine temperature.

5. Abnormal pressure in cooling system: Failure of return pipe may lead to abnormal pressure in cooling system. One of the functions of the return pipe is to adjust the pressure of the coolant and maintain the normal working state of the cooling system. If the return pipe fails, the pressure of the cooling system may be too high or too low, which will affect the flow of coolant and the heat dissipation effect.
