The cooling fan comes on when your car is cold, and it helps to cool down the engine. It’s important that you know about this function because if the cooling fan stops working, your car won’t start.
The cooling fan is a very important part of your car’s engine. When it starts to get hot, the cooling fan kicks in and pulls cool air through the radiator fins to keep things cool. The cooling fan doesn’t work all the time it only turns on when necessary, so you don’t have to worry about it being on while you’re driving around town or sitting in traffic.
If your car has been sitting for a long time without being driven, there’s a good chance that when you turn it on again, the engine will be cold enough for the cooling fan to kick in and start running again.
If this happens, make sure that you let your car idle for a few minutes before putting it into drive so that everything can warm up before you start moving around again.
How does it work?
The cooling fan comes on when the car is cold to prevent the engine from overheating. The air conditioning compressor also activates, drawing in hot air from outside of the car and releasing it through vents in the dashboard. This removes heat from the inside of the vehicle so that it can be dissipated by the cooling system.
Why does it come on when the car is cold?
When you first start your car, the cooling fan comes on. This is because the engine needs to be cooled, and the air intake is not blocked by any heavy snow or ice. The fan will run for a few minutes after you start the car, then go off automatically.
The reason why it comes on when the car is cold is because of the thermostat. The thermostat controls whether or not the cooling fans should run based on temperature and engine load.
When you start your car in cold weather, there is no water flowing through it yet because it has not been warmed up enough to begin circulating through the engine block. This means that the coolant inside of your engine won’t be hot enough to open up all of its valves yet which means no heat transfer from the combustion chamber to a radiator.
What is the purpose of the cooling fan?
The purpose of the fan is to cool your engine down by blowing air through it. If your cooling fan doesn’t have enough power to do this, then it could be damaged or broken. This will prevent your engine from running at its optimal temperature, which can lead to poor performance and even engine failure.
When should you replace your cooling fan?
The cooling fan comes on when the car is cold, but it’s not supposed to be on all the time. When you turn your car on and notice that the cooling fan is running at full power, it’s time to get a new one. This usually happens because there is water in your radiator that has not been drained out. The result is a cracked radiator.
That the cooling fan comes on when the car is cold and then stops after it reaches a certain temperature. We think this is because, when the car first starts up, there’s not enough heat in the engine to keep it warm, so the fan comes on to help circulate air around. Once the engine gets warm enough and the thermostat opens up, then more heat can get into the engine and warm it up without needing help from the fan.
