汽车散热风扇继电器的英文是'Automotive Radiator Fan Relay'。

The automotive radiator fan relay is a vital component in a car's cooling system. It is responsible for controlling the operation of the radiator fan, which helps to regulate the engine's temperature and prevent overheating. Without a functioning relay, the fan may not turn on at all, or it may run continuously, even when it is not needed, causing unnecessary wear and tear on the fan and draining the car's battery.

The radiator fan relay is typically located in the car's fuse box or power distribution center. It is a small, rectangular component that is easily replaceable if it fails. However, if you suspect that your car's radiator fan is not working correctly, it is essential to have it inspected by a qualified mechanic to diagnose the cause of the problem. This is because a malfunctioning fan can lead to serious engine damage, and in some cases, even a total engine failure.

In conclusion, the automotive radiator fan relay is a critical component in a car's cooling system. It helps to regulate the engine's temperature and prevent overheating, ensuring that your car runs smoothly and efficiently. If you suspect that your car's radiator fan is not working correctly, it is essential to have it inspected by a qualified mechanic to diagnose the problem and replace the relay if necessary.
