Electric cooling fan switches
Electric cooling fans cannot work alone. They work efficiently with the aid of supporting parts. The engine computer controls some, while others work like a thermostatic switch (electric cooling fan switch). Electric cooling fan switches sense temperatures in the car engine and turn the electric fan on or electric water pump if cooling is needed. Different electric cooling fan switches have different temperature settings in order to enable the required operation when it reaches a desired temperature.
The electric fan automatically turns on when the temperature of the engine goes over a set point with the help of a thermostatic fan switch. It will stop when the temperature returns to normal. A thermostatic fan switch that is used by the electric cooling fan is no more than a sensor.
A thematic fan switch is a mechanical switch placed inside the radiator hose to detect cooling system temperatures.
A thermal switch and relay is a type of fan switch very similar to thermatic switches which allow operations thermally and when the air conditioner is in use.
An electronic thermal switch is a mechanical switch that will detect temperatures of the incoming air and is mounted on the front of the radiator core.
It is normal for your cooling fan not to run all the time. The electric cooling fan is only needed when the engine’s temperature rises above a set level or when running your air conditioner. Running the cooling fan would be waste of electrical energy when it is not needed.
Electric cooling fans can be found on most autos with transverse mounted engines, most front wheel drive vehicles, and on many late model rear-wheel drive vehicles. They are used on FWD vehicles because the fan won’t require a belt drive and can be mounted independently of the engine location. Best yet, electric fans require less power for operation, which provide for improved fuel economy and performance. They are quieter and provide more precise cooling.
A mechanical belt-driven fan, on the other hand, can require 5 to 15 horsepower dependant on engine speed and size of the fan. Even a fan clutch to reduce drag at higher speeds is not effective against wasted power.
This should help you to make an informed decision in whether or not you think your electric cooling fan is in need of replacement. Electric cooling fan switches are not cheap, so be sure you need one before you buy.
