Is It Normal for the Fan to Keep Running for a Few Minutes After Parking?
2 Answers
The fan in a car serves a cooling function. Therefore, after parking, if the coolant temperature is too high, the vehicle's computer will automatically calculate the fan's speed and duration. The higher the coolant temperature, the longer the fan will run to protect the engine. This is a normal phenomenon, so there's no need to worry. Below is more related information: Reasons why the fan keeps running continuously: However, if the fan runs for an excessively long time and the engine temperature has already dropped but the fan continues to spin, it might be due to a loose circuit connection. You can try unplugging the fan's wiring harness to perform an independent power-off treatment. Additionally, this situation could also be caused by a faulty coolant temperature sensor or a stuck fan relay contact. In such cases, simply replacing the faulty part at a repair shop should resolve the issue. Therefore, if the fan continues to run after turning off the engine, you can check whether it's normal cooling or if there's an underlying problem.
I remember I've been driving for almost twenty years. It's quite normal for the fan to run for a few minutes after parking, especially in summer or after long-distance driving when the engine gets too hot and needs cooling. Usually, it stops automatically after two or three minutes because the fan is activated by a thermostat to help cool the engine and prevent overheating. However, if the fan keeps running for a long time in winter or when the engine isn't very hot, it's time to check it out—it might be a faulty sensor or a coolant leak. Once, my car's fan wouldn't stop, and the temperature gauge started rising, so I rushed to the repair shop to fix the thermostat. Always keep an eye on it; if it runs for more than five minutes or makes a buzzing noise, be alert and get it serviced promptly—don't delay.
