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. Do both elements heat same time water heater? when does the bottom heating element come on.
Should both my 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.

Because most radiators are rectangular shaped and not square. If the radiator is square 1 fan can cover most of the radiator nicely but when they are rectangles you need 2 fans to cover the majority of the radiator.
Do cooling fans run all the time?
It can be normal for the cooling fans to run constantly under certain conditions. If the car is hot enough, they may be barely keeping up with demand and stay on. Also, most cars will run the fans at a high speed if the A/C is turned on.
How many cooling fans are in a car?
A lot of drivers’ 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.
Can a car run with one fan?
Yes, of course. But, the engine might get a little hot, and it isn’t a good idea to continue to do so without getting the other fan (or two) repaired or replaced… If there is more than one fan, there is a reason for it.
Is a cooling fan the same as a radiator fan?

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.
What controls the radiator fan?
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 are car lovers called?

Why is my radiator fan continuously running?
The reason behind this is quite simple . After turning the engine off, the ECU unit tells the fan to continue running as the coolant is still hot. Until the temperature comes down to normal, it keeps running which makes a bit of sound. DONT WORRY ITS NORMAL.
Should radiator fan turn on when AC is off?
The AC controls may operate the fan from a place in the control circuit after the normal temp sensor so everything is OK when the AC is on. Also the Fan may be on continuously when the AC is operating.
Is the radiator fan Part of the radiator?
The Cooling fan sits on the radiator at the front of the car and draws air across the unit to cool it down. The radiator works by spreading the coolant pumped from the engine across a large surface area where the heat can be dissipated.
Does radiator fan affect AC?
A lousy radiator fan can create car air-condition (AC) issues. This is because the radiator cooling fan creates double the amount of air that the condenser fan. The radiator fan pulls air through the condenser, which removes the heat vapor of the refrigerant inside.
What is the fan in front of the radiator called?
Electric fans are found in the front part of the radiator and are also referred to as “pusher fans”. These pusher fans receive the air which comes through the grille area.
How long can you drive a car without a radiator fan?
Typically, you would be alright for the first 5–7 miles or about 2.5 minutes which is when the thermostat opens up and you can get heat. At that point turn your heater on fully, which will help cool the coolant. As long as you drive around 40 MPH then the engine should stay within a safe temp range.
Can you drive without a fan clutch?
You will be fine, I had Trailblazer SS that I drove for 2 weeks with no fan while I waited for a tune update in the wintertime.
Do you need a fan clutch?
The sole purpose of your engine’s fan system is to cool it down, and without the fan clutch activating, the fan itself cannot turn and keep your engine at the proper temperature for peak performance. The fan clutch is a thermostatic device, meaning that it’s operated by the heat produced under the hood.
What tells the cooling fan to come on?
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.
How do I know if my cooling fan is working?
The radiator fan should be running at more RPMs than the motor. If it is not, the fan clutch is bad and needs to be replaced. Some radiator fans are solid mounted, with no fan clutch. If your radiator fan is solid mounted and the fan is not working, your belt is bad and needs to be replaced.
How do you know if your cooling fan is bad?

Why does my fan continue to run after shutting the engine off?
This is normal operation. It’s normal. The electric fan is running independently of the engine in order to bring down the temperature of the coolant in the radiator. Most cars since the early to mid 90s have independent electrically operating cooling fans.
Is radiator fan and condenser fan same?
There’s no difference, really; both remove waste heat generated by the engine’s combustion process. A radiator is used in water-cooled engines and the fan removes heat from the cooling fluid in the radiator before it returns to the engine.
