What controls an electric engine cooling fan?
The PCM controls fan operation; it uses the signal from the ECT or engine coolant temperature sensor. This sensor senses the temperature of the engine’s coolant and sends a variable voltage signal to the PCM. The PCM operates the fan motor through the engine’s cooling fan relay.
What is used to turn an electric engine cooling fan on and off?
ELECTRIC COOLING FAN OPERATION The engine coolant sensor or a separate engine temperature switch is used to monitor engine temperature. The fan will then cycle on and off as needed to maintain the coolant temperature. So the fan runs mostly at idle or low speed when the engine is at normal temperature.
How much horsepower do you gain with electric fan?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
Does the thermostat control the radiator fan?
The thermostat opens and closes when there is a need to. How it works is simple. When the temperatures outside are cold the thermostat stays closed and the coolant stays in the engine. When the coolant reaches the working temperature the thermostat opens and the coolant circulates through the cooling system.
What temp should my electric fan turn on?
