What will happen when a car cooling fan is continuously running?
A car cooling fan is an important part of the engine cooling system. It helps to keep the engine from overheating by drawing air through the radiator and over the engine. When the engine is running, the cooling fan is usually turned on and off by a thermostatic switch. The thermostatic switch senses the temperature of the coolant and turns on the cooling fan when the coolant temperature reaches a certain level.
If the cooling fan is continuously running, it can be a sign of a problem with the cooling system. Here are some of the possible causes of a continuously running cooling fan:
- A faulty thermostatic switch. The thermostatic switch may be stuck in the "on" position, causing the cooling fan to run even when the coolant temperature is not high enough.
- A problem with the wiring. The wiring to the cooling fan may be damaged, causing the fan to run continuously.
- A problem with the fan motor. The fan motor may be faulty, causing the fan to run continuously.
If the cooling fan is continuously running, it can put a strain on the electrical system and the cooling system. It can also lead to premature wear of the fan motor. If you notice that the cooling fan is continuously running, it is important to have the cooling system checked by a qualified mechanic.
