Are both radiator fans supposed to run at the same time?

Are both radiator fans supposed to run at the same time?

Both radiator fans should always run when the AC compressor is engaged. 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.

When should engine cooling fan come on?

Most fans should come on when the coolant reaches about 200 to 230 degrees. An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only ‘lock up’ when needed.

How often does the radiator fan turn on?

Temperature will often determine the time that a radiator fan starts up. A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit.

Why does my car have 2 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.

Can you drive with only one radiator fan?

Yes, technically your engine does not need a cooling fan to operate. If the radiator does not have cool air blowing on it constantly, it will overheat eventually, so you’d need the perfect combination of weather and traffic to drive effectively without a radiator fan.

How do dual radiator fans work?

Dual Radiator Fan- dual fans are assembled in two’s. They operate together to move air through the radiator core, providing a more effecting cooling effect. Dual radiator configurations are suitable for large engines that need a higher CFM rating.

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 many radiator fans does a car have?

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.

Does a radiator come with fans?

When you drive, air is forced through the grille, through the condenser and through the radiator. The air removes heat from the coolant and the A/C system. But when the vehicle is idling or moving slowly, too little air enters to keep things cool. That’s where the radiator fan comes in.

Why does my radiator fan come on when I start my car?

What Is The Function Of The Radiator Fan? The engine contains a combustion chamber where explosions take place to provide power and heat the car. These explosions cause the engine to heat up extremely quickly and can sometimes lead to overheating. This is a reason why the radiator fan turns on when the car starts.

Why does my cooling fan stay on all the time?

If the cooling fans are staying on at all times, this is another (less common) symptom of a possible problem with the cooling fan relay. If the relay shorts internally, it may cause power to be permanently switched on, which will cause the fans to run at all times.

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 are two radiator fans running at the same time?

Obviously if the car is designed for two fans to run at once, then it’s not getting enough airflow at standstill and that causes my car to overheat. But if it is supposed to be that way, that means it’s something else.

Is the a / C fan supposed to work at the same time?

But if it is supposed to be that way, that means it’s something else. They work separately, unless the car is hot, then they both come on. Does the A/C fan even work?

Can you turn off electric fans on Toyota?

Electric fans are a very popular mod among the Toyota off road crowd. The ability to turn your fans off for water crossings is very nice. Along the same lines of the original post; do the fans simply alternate duty back/forth, or is there more logic to it than that?
