Why does my radiator fan come on as soon as I start my car?
The job of the radiator is to keep the coolant at the right temperature so that when it travels back to the engine, it is able to take on more heat, and prevent the engine from getting too hot. This is a reason why the radiator fan turns on when the car starts.
Why is my car cooling fan so loud?
One such problematic issue, the excessively loud radiator cooling fan, is a common plague many automobile owners will experience. Your radiator fan should be audible. Worn bearings, bent or broken blades, and unbalanced rotating assemblies can cause a fan to screech, howl, or otherwise make noises it shouldn’t.
How long can I drive without radiator fan?
Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.
What causes engine cooling fan not to work?
What Can Stop Your Fan From Working: Defective temperature switch, (ECT) sensor or other sensor Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.) Bad fan motor Defective fan control module
What temperature should the engine cooling fan come on?
The fan will then cycle on and off as needed, to maintain the proper coolant temperature. So, the fan runs mostly at idle or low speed, when the engine is at normal temperature. Most fans should come on, when the coolant reaches about 200 to 230 degrees.
Why is the engine cooling fan not working?
The temperature sensor determines when the radiator fan comes on by reading the cooling system temperature. If the sensor isn’t working, your fan won’t come on because it won’t know that the temperature is hot enough to require activation, which can frequently lead to overheating.
When does the engine coolant fan kick on?
Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit. A radiator fan uses its fast spinning blades to draw in outside air. This in turn cools the antifreeze and water that’s within the radiator, which keeps the vehicle’s engine cool as well.
