The temperature sensor determines when the radiator fan comes on by reading the cooling system temperature. The sensor is usually located in the car .
Thermostatically controlled motors do not work the fan until the engine coolant rises above normal operating temperature, and then switch off when it has cooled down again.
To check that the fan is working , listen for it cutting in and out, and watch the temperature gauge.
If the engine shows signs of overheating, stop and . Is the cooling fan motor working on your vehicle? As the engine operates the coolant temperature will continue to rise, and if .

When the coolant temperature reaches somewhere between 2and 2degrees (depending on the car) the coolant fan should automatically turn on. Be aware of this if you are working in the engine compartment and the engine is hot. Input from the engine coolant sensor, ambient air temperature, vehicle speed sensor and other sensors may be used by the PCM to determine when the fan needs to be energized.
During the winter months, your radiator fan saves even more energy when enough cool air flows through the radiator on the highway.
Next are some fan circuit key points . Thank you for mentioning the difference in temperature of upper and lower radiator hoses. The fan fuse link was burnt out. Now, I will spent the few dollars, and time to replace the thermostat. FORD Supderduty ~ Fan Clutch ~ How to Lock-Up Manually - Duration: 4:18.

This feature is not available right now. When an engine is running, it produces heat, and that heat dissipates so that the engine does not become too hot and overheat. A radiator fan exchanges heat in the engine.
Many cars have fans that are attached to the crankshaft or water pump and are constantly turning and providing cool air.
The cooling fans, with between four . Other cars use electric fans controlled by thermostats that tell the fans when to come on. If the fan stops turning, then the car likely will overheat (especially at low speeds or idling), which can cause the . On many vehicles, there may be two fans : a main cooling . Most modern vehicles use electric cooling fans to help pull air through the radiator so that it can keep the engine cool.
