What causes cooling fan to stay on?
Cooling fans stay on at all times
If the cooling fans are staying on at all times, this is another (less common) symptom of a possible problem with the cooling fan relay. If the relay shorts internally, it may cause power to be permanently switched on, which will cause the fans to run at all times.
What causes cooling fan to stay on after car is off?
When the engine is running, the coolant circulates and flows to the radiator, where heat is dissipated. When the engine is turned off, the coolant doesn't circulate, and the heat stays trapped, therefore prolonging the engine from cooling. Running cooling fans help cool down the engine even after you turn off the car.
Why won't my cooling fan shut off?
The most common reason that your Air Conditioner fan won't turn off is because a stuck relay keeping the circuit closed. ... Double-check the thermostat and make sure the fan is not set to ON, and that it still runs when switching it to AUTO or OFF (if your thermostat has an OFF setting).
Is the radiator fan always supposed to be running?
Temperature will often determine the time that a radiator fan starts up. A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit.
What does a bad radiator fan sound like?
Q: What does a bad radiator fan sound like? ... In some cases, when your radiator cooling fan clutch fails, it will develop a whirring or clicking noise. The noise could result from a bearing that is out of place or a bent fan blade that is touching other components.
When should a radiator fan kick on?
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
When should the cooling fan come on?
Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective.
Where is the cooling fan sensor located?
It is most often located close to the thermostat of the cooling system or inside of it. The cooling system is located beneath the air intake pipe and behind the right cylinder.
How do I know if my radiator fan motor is bad?
The first symptom or sign that something has gone wrong is that your cooling fan doesn't come on at all. This is the most common symptom of a faulty cooling fan motor, but it may not be one you notice while driving your vehicle. If the motor burned out or starts to fail in any way, the cooling fans are disabled.
Where is the radiator cooling fan relay located?
The fan relay is usually located near the bottom of the engine compartment on a metal frame member. The metal acts as a heat sink to keep the fan relay cool. So, unplug the connector at the relay and repeat the check for power. If you get power, you've got a bum relay.
