Want this question answered?
Themo switch located on the radiator Or intake manifold , that is usually runs a relay fOr the. Oolong fan
A faulty thermostatic switch would prevent the fan switching on when the engine is hot. (Located in the side of the radiator on my 1991 golf)
give answer
There are several possibilities that come to mind. Coolant loss (IE) leak in cooling system Thermostat stuck shut Water pump failure Thermostatic fan clutch failure Radiator Cap failure Collapsed radiator hose Cooling passages obstructed Dirt and debris obstructing radiator Fan shroud, air dam, valances broken or missing
Depends on the model and year. Some have a thermo switch on the radiator. Check for a wired plug on the radiator. Some fans are controlled by the ecu using data from the coolant temp sensor.
You might take a look at the cooling sensor,which activates the fan when its reaching a certain degree .or it could be time to replace the fan due to bad electrical wiring.

One of the fans operates independently of the air conditioning system. The other fan will only operate if the air conditioning system is turned on and the engine needs extra cooling to exhaust the heat transferred to the engine coolant by the operation of the A/C. They both are tirggered into operation by thermostatic switches but not the same switches. They are independent of one another. CAUTION: Do not confuse these thermostatic switches with the actual cooling system thermostat contained in the engine block that controls the flow of the coolant.
Rust and sediment can accumulate in the cooling system. Flushing the radiator helps keep the cooling system clean.
The radiator cap controls cooling system pressure.The radiator cap controls cooling system pressure.

Check the operation of the cooling fans. However, if you are driving at highway speeds the cooling fan would not be needed, therefore it could be a defective thermostat or a clogged radiator, in which case a radiator shop could clean and refurbish it. If not driving at highway speeds, the check not only the fan, but the thermostatic switch controlling the fan and the fuse/circuit breaker for the fan system
