It varies depending on your year, make, model, and engine size.
It is in the passenger side coolant tank on the radiator. If the light is on and the coolant is at the proper level then the sensor is defective. To replace it you will have to drain the radiator. Disconnect the wire and remove the clip and remove the sensor.
Test or replace the sensor in the radiator side tank.
The radiator fan sensor switch or the radiator fan motor are at fault (maybe even both). Wire the fan motor direct to see if it will run, if it does, replace the sensor switch. If the fan motor doesn't run, replace the fan motor before you buy a new sensor. If after replacing the fan motor, the fan still doesn't run, then replace the sensor.
its on the radiator looks like a big bolt with wires on it.
Replace the thermo sensor...
Answerthe sensor is located about 4 inches down inside of the radiator....probably need to replace radiator. Wrong.. that is the level sensor, and it can be replaced by itself by removing the clip around the sensor and pulled out, however it will leak coolant if the radiator is full so be careful. the temprature sensor is on the block by the the thermostat housing. follow the upper radiator hose to the engine and your hand will hit the temp. sensor. it has electrical wires on it, disconnect them and remove the sensor with the correct wrench. replace the sensor and reinstall the electrical clip, the sensor is around 13 dollars
If it is a temperature sensor, it is usually located on the top of the engine near the thermostat. If it is a "low coolant sensor", then it is located in the radiator (it will be the only item in the radiator that has a electric wire going to it) Either way, you would drain the coolant enough to be below the sensor, and then remove it and replace it with a new one. They are usually under $10-$20
Is the cooling fan working? Make sure radiator are not collapsing under pressure Make sure radiator cap is holding pressure Test cooloant temperature with a thermometer perhaps gauge or sensor is defective
how to use heating system, radiator, conduction in a sentence
The 2004 Chevrolet Malibu coolant sensor float is located in the radiator. The coolant sensor float replace the level of coolant to the instrument panel.
Either the sensor is shot or the radiator is hot. Does it shut off after a period of time? If not, replace the sensor.
A type of heating system uses a radiator in which thermal energy is transferred by conduction
