Engines operate at their most efficient when they’re hot but not too hot. The fan turns on when you’ve stopped driving because no more cooling air is flowing into the engine bay. This causes the temperature to rise, automatically triggering the fan.
Are both radiator fans supposed to run at the same time?
The answer to your question is yes both fans will run when your at 230 degrees, if you have the parking lights on and your at 212 degrees one fan will come on, and when you have the air conditioning on you have one fan on as well.
How do I know if my cooling fan is bad?
- 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.
Does the engine fan always run?
A fan shouldn’t run continuously, and is intended to operate at its correct temperature (in terms of engine temperature, the temperature varies between different cars), to cool down the engine before it gets overly hot.
Should radiator fan turn on 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.
What tells the cooling fan to come on?
On most systems, there is a coolant temperature switch, that turns the fans on and off. First, locate the coolant temperature switch and unplug it. But, be sure you have the right one.
Why is radiator fan always on?
The situation when the car radiator cooling fan keeps running constantly can be caused mostly by a failing coolant temperature sensor or its wiring, broken fan start relay, damage to the electrical wires, electronic engine control unit (ECU) problems.
Can I drive my car if the fan is not working?
Logically, however, the cooling fan keeps the cooling system at the optimal temperature to prevent the hotter than normal engine temperatures, as mentioned above. As such, you should never drive your vehicle if the cooling fan isn’t working even though you can. It’s crucial to maintain ideal operating conditions.

How long should car fan run after off?
It is ok for the engine cooling fan to keep running for a few minutes after turning off the car. Your car fan will run for a few minutes after you turn off the car then turn it off. This is normal in many vehicles, such as BMW or Mercedes-Benz. The radiator fan may run up to five minutes and sometimes longer.
Why do cars have 2 radiator fans?
The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. On many vehicles, there may be two fans: a main cooling fan for the radiator, and a second fan for the condenser. Both fans should come on when the A/C is on. The engine may also run hot and overheat, too.
How many radiator fans does a car have?
A lot of vehicles will actually have two radiator fans. One, both or neither may be running at any given time depending on the conditions. When you are cruising at highway speeds, the air rushing over the radiator and around the engine will help control the heat.
Is radiator fan and cooling fan the same?
The cooling fan is also known as a radiator fan because it’s mounted directly to the radiator in some engine layout. Typically, the fan is positioned between the radiator and engine as it draws heat to the atmosphere. In front-wheel cars, the cooling fan used is an electrical component powered by the battery.
What happens when a cooling fan goes bad?
If the cooling fan motor fails, the blades don’t spin and they don’t generate air flow. At that point, the engine temperature continues to climb until your engine overheats. Once your engine overheats, you get other warning lights to come on indicating the problem.
What does a bad cooling fan sound like?
In some cases, when the radiator cooling fan motor fails, you’ll notice a loud clicking or whirring noise that changes as you rev your engine.
Can fan cause car to overheat?
Faulty Fan
If the fan is barely working or not working at all, the engine coolant will be recirculated through the engine before it’s cooled down. This will cause your engine to overheat.
Should fan be on auto or on?
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.

Why do my radiator fans only kick on when my AC is on?
The most likely culprits are a thermostatic switch, fan resistor, temperature switch, low-speed or high-speed relay, or a wiring issue. If the vehicle overheats, care should be taken when driving to prevent further damage by overheating.
