Why is my Honda radiator fan not working?

If the radiator fan begins working, this is an indication that the fan relay is bad. If the fan switch relay is giving off the appropriate readings and is in working condition, move on to the next step. The thermo switch (also called the cooling fan switch) sends a signal to the cooling fan, so the fan turns on if the coolant gets too hot.

Why do you need a radiator fan in a car?

To stop the engine from overheating, we take the help of coolants that flow through a radiator into the engine. The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.
