Are both radiator fans supposed to spin?

Are both radiator fans supposed to spin?

They work separately, unless the car is hot, then they both come on. Does the A/C fan even work? Turn on the A/C to see if it does come on.

Which way should my radiator fans be facing?

So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top.

How close should a fan blade be to a radiator?

The fan is designed to create negative pressure behind the radiator to pull air through. But the farther away the fan is from the radiator, the less effective it becomes. Flex-A-lite recommends that the fan blades be within 1 inch of the radiator and no more than 2 inches away.

Are radiator fans different?

Push vs. Pull – electric radiator fans come in two different types – push and pull. Pull fans mount on the inside of the radiator, and they pull the air across the radiator. They are not interchangeable, so be sure you know which type is in your car.

Should my radiator fan always be on?

Fan Trigger 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.

Will a bad radiator fan cause AC not to work?

Reason #5: Faulty Cooling Fans When fans aren’t properly functioning, your condenser may not receive properly cooling. Over time, this can cause your car to start emitting only hot air. The best way to check if the cooling fan is broken is through a visual inspection.

Should fans push or pull through radiator?

Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator. Always choose a puller fan but if space is an issue then use a pusher fan.

Should the radiator fans push or pull air?

Preference should be given to a “pull” vs. a “push” fan. Mounted on the engine side of the radiator, a pull fan does not interfere with airflow at highway speeds. All shrouded fans should be on the engine side of the radiator.

Does a pusher fan need a shroud?

Remember, shrouds cannot be used on pushers. Fan shrouds need a way to mount to the radiator.

Is it better to push or pull air through a radiator?

A Push configuration is more efficient in cooling when its blowing cool(er) air from outside the plenum through a radiator. A Push also makes your build louder. In Pull configuration the fan or fans are drawing an air stream out of the radiator.

Is radiator better than fan?

According to Mark Gallina, liquid cooling more “efficiently distributes heat over more convection surface area (radiator) than pure conduction, allowing for reduced fan speeds (better acoustics) or higher total power.” In other words, it’s more efficient, and often quieter.
