What temp does fan come on on Mini Cooper?
High speed is switched on at 112° C (234° F) and remains on until the system coolant temperature drops by 4° C (39° F) at which point the system will revert to Low Speed. The cooling fan will also operate on Low Speed when the Air Conditioning is switched on and system pressure reaches 8 bar (116 psi).
When should the cooling fan come on?
To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees.
What tells the cooling fan to come on?
Fan Trigger The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.
Should both radiator fans turn on?
Both fans should come on when the A/C is on. If one or both fans fail to come on, the lack of additional cooling provided by the fan may cause poor A/C cooling performance, and it may cause the A/C compressor to overheat and fail. The engine may also run hot and overheat, too.
How do you know if your radiator fan is not working?
These are the most common signs of a faulty radiator fan assembly in need of replacement:
- Engine Overheating. When the radiator fan isn’t functioning properly, it is not able to adequately cool down the car’s engine.
- Air Conditioner Function Diminished.
- Loud Noise Coming From Radiator Fan.
Why does the fan on my Mini Cooper keep running?
The most common cause is the coolant expansion tank failing. Fixing this problem is easy. This is not an expensive repair. Additionally, you need to check the thermostat housing.
Should radiator fan run when AC is on?
When the AC compressor is activated, it is actually expected that the radiator fan runs. For instance, the radiator fan is needed when the temperature sensor of the cooling fluid in the lower tank reaches approximately 212F.
How is radiator fan controlled?
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it’s not working, the fan won’t turn on when it needs to, which means the engine might overheat.
What controls radiator fan speed?
In addition to the power, ground, and tach signal, 4-wire fans have a PWM input, which is used to control the speed of the fan.
How do I know if my radiator fan is not working?
If the fan fails, the condenser can’t do its job and the A/C system will blow warm air. Warning lights are on: A faulty radiator fan can trigger warning lights such as the engine temperature and check engine lights. In some cases, the A/C system may also display some type of warning, such as a flashing A/C button.
What does the cooling fan do on a Mini Cooper?
The cooling fan moves air past the radiator to lower the engine coolant temperature. Without it, the engine will overheat at speeds below 40 miles per hour. Replacement can be done at home with a basic tool kit and an afternoon. This article applies to the Mini Cooper R50 and R53 (2001-2006).
How do you replace the cooling fan on a Toyota Corolla?
Unplug the cooling fan. With the new fan removed, reverse the instructions to install the new fan. Top off the cooling system at the radiator and overflow tank. Loosen the bleed screw at the upper radiator hose and start the engine with the heat on max high. Close the bleed screw once coolant exits through it.
What should I do if my Mini’s cooling fan is dead?
If your Mini has only one cooling fan, you can instead turn your A/C to the max setting. If your Mini’s fan is dead, it’s time to replace it. Removal of the Aero kit bumper may have some differences.
