It is the coolant temp sensor near the upper radiator hose.
Check the temperature sensor
Its located on the radiator passanger side about 3" below the radiator cap.
there's no switch, it has a temperature sensor.
The engine coolant temperature sensor is the two wire sensor near where the upper radiator hose attaches to the engine.
the sensor is located next to the thermostart, driver side of the cylinder head.
The temperature sensor on a BMW 325i is located on top of the engine, near the upper radiator hose. It constantly monitors the temperature of the coolant and triggers the cooling fan as needed.
If radiator cooling fan it turns on only when temperature sensor reaches temp needed to cool car, then when enough cooling takes place, it gets told by sensor to turn off.
There is a sensor that detects temperature to turn the fan on in some vehicles, this sensor may need to be replaced.
A/C or defroster on Relay stuck in closed position Temperature sensor not sensing proper temperature
The computer uses the coolant temperature sensor to decide when to run the fans. It is below the radiator cap on the cylinder head.
The coolant temperature sensor on a Subaru is located on top of the engine near the upper radiator hose. It constantly updates the vehicles computer to regulate the speed of the cooling fan.
The radiator fan will start to work once your engine reaches a certain operating temperature.
There is a temperature sensor.
The water temperature sensor on a 2002 Kia Sedona is located on top of the engine, near the upper radiator hose. It relays the temperature to the vehicle's computer and triggers the cooling fan to come on.
Radiator plugged or restricted? Cooling system airbound? Water pump not circulating coolant? Radiator cap defective? Radiator hoses collapsing under pressure? Defective gauge/cooling temperature sensor?
Check the temperature at the radiator when hot Cooling fan is designed to come on only when:A/C Compressor is on (either during cooling or defrosting) orwhen coolant temperature exceeds 235 degrees Fahrenheit
The coolant temperature sensor is the two wire sensor near to where the upper radiator hose attaches to the engine. The outside/ambient temperature sensor is behind the front bumper, in front of the radiator.
Problem with the temp sensor.
On the 3.8 V6 it is below the throttle body on the front of the engine. You do not have to drain the radiator, just remove and replace. Then top off the radiator coolant.
The 1995 Oldsmobile Aurora cooling system temperature sensor can be found on the front of the engine. The sensor will be above the thermostat housing.
Look at the rear of the radiator approx. 1/3 down from the top
Should be located at the rear of the radiator approx. 1/3 from the top unscrew to replace
The engine computer uses the coolant temperature sensor that is located close to where the upper radiator hose attaches to the engine to decide when to actuate the fan.The engine computer uses the coolant temperature sensor that is located close to where the upper radiator hose attaches to the engine to decide when to actuate the fan.
check to see if the thermostat is hung open or your temperature sensor for your fan is out and causing your fan on your radiator to run continuously when key is on.
