Does the engine fan always run?
An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only ‘lock up’ when needed. Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F.
Why is the fan running in my engine?
It is possible that this problem of your car’s fans constantly running is some sort of mechanical or electrical error from a poor sensor or other component. There are temperature sensors and some cars have separate sensors for the gauge itself. The fan can be shut off when the engine temperature warrants.
When should engine fan run?
To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees.
When does the engine fan turn on in a Toyota Corolla?
The Radiator Cooling Fan Relay (8) energizes when both the Engine Main Relay (7) is energized and the Engine Cooling Fan switch (10) is closed. The Radiator Cooling Fan Relay Contact (8) is normally closed, so when the Radiator Cooling Fan Relay (8) is energized, its contact is open.
How does the cooling fan work on a Toyota?
One of the more important components is the cooling fan. The fan lowers the coolant temperature after the coolant has finished its cycle through the engine. A Toyota’s cooling fan is powered by an electric motor.
Why is the radiator not working on my Toyota Corolla?
If everything else seems on the up and up, the springs in the fan clutch have worn past the point of proper function and can no longer do their job. There are many reasons why your Toyota Corolla’s radiator fan is not working. Of all the ones listed above, start with the coolant level, then check the fuse. After that, the order isn’t so important.
What is the Green relay on a Toyota Corolla?
The green Relay (the one the guy is calling a “Condensator” ROFL) is the Radiator Cooling Fan Relay (8) and the Grey relay on the top right is the Engine Main Relay (7).
