Where is the thermo cooling fan switch located?
The thermo cooling fan switch is typically located near the engine or radiator of a vehicle. This switch is responsible for activating the cooling fan when the engine reaches a certain temperature, helping to prevent overheating.
Understanding the Thermo Cooling Fan Switch
The thermo cooling fan switch is a temperature-sensitive device that monitors the coolant temperature in the engine. When the coolant reaches a predetermined temperature, usually around 200-220°F (93-104°C), the switch closes, completing the circuit and turning on the cooling fan. This helps to dissipate heat from the engine and maintain optimal operating temperatures.
Locating the Thermo Cooling Fan Switch
The exact location of the thermo cooling fan switch can vary depending on the make and model of the vehicle. However, it is typically found in one of the following areas:
- Near the radiator or cooling system components
- On the engine block or cylinder head
- In the engine compartment, often near the thermostat housing
To locate the thermo cooling fan switch, you can consult your vehicle's owner's manual or repair manual, which will provide specific instructions and diagrams for your make and model.
Checking and Replacing the Thermo Cooling Fan Switch
If you suspect an issue with your vehicle's cooling system, it's a good idea to check the thermo cooling fan switch. You can use a multimeter to test the switch and ensure it is functioning correctly. If the switch is faulty, it will need to be replaced to restore proper cooling system operation.
Replacing the thermo cooling fan switch is generally a straightforward process, but it's important to follow the manufacturer's instructions and use the correct replacement part for your vehicle. Attempting to bypass or ignore a faulty thermo cooling fan switch can lead to engine overheating and potential damage.
Which switch on the fan makes it colder?
Which way should a ceiling fan turn to keep you cool in the summer? During summer months, your ceiling fan blades should be set to spin counterclockwise. When your ceiling fan spins quickly in this direction, it pushes air down and creates a cool breeze.
Can you drive with a broken coolant fan?
While the vehicle is in motion and air is moving through the radiator, a broken car radiator fan will have little impact. When stationary or spending time in heavy traffic without a working fan, your engine may overheat, which could cause irreparable and expensive damage.
Where is the thermo coolant fan switch?
The cooling fan switch is usually on the radiator assembly. Not all engines come with a fan switch. In some vehicles, there's only an engine coolant temperature sensor that alerts the powertrain control module to operate the fan. Drain coolant from the radiator before you remove the switch.
Where is the best location for the thermo fan switch?
The temperature probe should be plugged into the system where the coolant is hottest—generally, the thermostat housing, in the coolant passages adjacent to it, or in the water jacket of the cylinder heads.
Will my coolant sensor make my radiator fan not turn on?
The most common reasons for a radiator fan not working can be a blown-out fuse, a bad relay, or a broken wire. The faulty coolant temp sensor might also be a reason behind it. Whatever the case, a dysfunctional radiator fan can be fatal.
Where is the cooling fan temperature sensor located?
The ECT sensor is typically near the thermostat in the cylinder head or thermostat housing. The ECT sensor is typically near the thermostat in the cylinder head or thermostat housing. Many vehicles also have a second ECT sensor on a different part of the engine or radiator.
What is a thermo fan switch?
The thermo fan switch is designed to control operation of the electric thermo fan(s). The thermo fan switch responds to changes in engine coolant temperature, providing circuit switching during a predetermined temperature range allowing fan operation.
Where is my coolant temperature sensor located?
Where is the Coolant Temperature Sensor located? The coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath the air intake pipe.

How do I know if my coolant fan switch is bad?
Quick check is to pull the wire off the switch- the fan should stop. If the coolant temp is below ~200*F and the fan comes back on when you reattach the wire, the switch is faulty.
