Your Electric Cooling Fan is Not Functioning Properly?
Is your car AC not functioning properly? If your answer is yes, there is a high probability that your electric cooling fan is not functioning properly. Most of the times, we tend to ignore the overheating of the car, thinking the air conditioning is at fault.
But actually, in a high percentage of cases it is the cooling fan which is at fault. Talking in technical terms, the efficiency of the Car's engine depends, among other factors, on the amount of heat removed from it. And responsible for removing this heat is the cooling fan. Not long ago, belt driven fans were used, but these days , electric cooling fans are used which are more efficient than their belt driven counterparts.
An electric cooling fan is basically made up of two parts- a fan motor and the circuit, which consists of the fan switch and the relay. The switch sends power or ground to the relay. It is the function of the switch in an electric cooling fan to sense the internal temperature and switch on the cooling if required. Usually, when the car is running on the highway, due to high speeds, engine gets the cool air required from the environment itself, so there is no need for the cooling fan. But when the car is being driven at a very low speed or the engine is idling, the engine requires additional airflow to keep it from overheating.
This additional airflow is provided by the electric cooling fan. The proper upkeep and maintenance of the electric cooling fan is vital to your car's performance. If you are planning to take your car to a doctor for a check up (I mean a mechanic), make sure it is a qualified mechanic. A qualified mechanic has various ways to check whether the electric cooling fan is in proper working condition or not.
One of the ways a mechanic is most likely to use is to directly check the source. He would verify whether there is proper power supply and ground given to the electric fan motor. Another way to identify any problems with your electric cooling fan is to supply a 12V power to the motor and see if it runs. Electric cooling fans are a dangerous car part and must be looked after with extreme care. They not only save power but also help in reducing the noise of the vehicle. So always keep in mind, a healthy electric cooling fan means a healthy car.
