How do automatic radiator fans work?
How Does A Radiator Fan Work? A mechanical fan is connected to the engine directly by drive pulleys. This type of radiator fan is controlled by a thermal fan clutch that senses radiator heat. After sensing the heat temperature, the radiator fan turns on when the engine is running at a higher temperature.
What does the cooling fan do in the cooling system?
The fan system works by forcing air flow through the radiator. Its function is to facilitate and support the engine’s temperature management.
How do you change the cooling fan on a Toyota Camry?
Disconnect the cooling fan connector. Connect battery and ammeter to the cooling fan connector. Check that the cooling fan rotates smoothly, and check the reading on the ammeter. Standard amperage: 8.0 to 12.0 A at 20 C (68 F) If not, replace the cooling fan.

The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed. A failed sensor can cause the fan to run excessively or not run when cooling is needed. The cooling fan in a Toyota has a relay to regulate when power is provided to the fan.
What should the ammeter reading be for a Toyota Camry?
