Having spent 27 years as a mechanic, most of the time they draw air from the front of the vehicle and pull it through the radiator and AC condenser. Put your hand in front of the radiator when the fan is on, you should feel a light suction, put your hand on the other side, (fan side) and it should be blowing your hand towards the engine. use extreme caution not too touch the fan blades.

The electric cooling fan on a 97 Dodge Neon turns the blades in a clockwise rotation. This pulls air through the radiator and across the engine.
Cooling remains same irrespective of the motor rotational direction.
Cooling fans use electric motors which operate by magnetism. As the direction of the current flow reverse, the magnetic poles reverse and hence the change in direction.
The 1997 Ford Mustang uses an electric engine cooling fan . The electric motor and the fan it drives are in a housing attached to the radiator between the engine and the radiator
Electric cooling fan? Fan placed behind radiator to aid in engine cooling activated when engine coolant temperature exceeds 235 degrees F or when A/C or defroster is engaged
No, Should be driven off the pulleys by a belt unless someone has installed an electric fan for extra cooling
There is a good chance that your radiator cooling fan is not working properly. Some vehicles have a mechanical clutch that causes the radiator fan to operate when the vehicle is stopped or at low speeds. These clutches can wear out and need replacement. Other vehicles have an electric radiator fan that is controlled by a thermostat placed somewhere in the vehicle's engine coolant flow. Electric fans can malfunction and not pull enough air through the radiator to keep it properly cooled. The electric cooling fan's thermostat can go bad too.
The engine computer uses the engine coolant temperature sensor to decide when to run the electric radiator fan. It is located very near where the upper radiator hose attaches to the engine.
Look at the blades of the fan. They are "slanted" one way or the other. They have a given pitch. The pitch and direction of rotation determine which way the air will move when the fan is on. Now that we agree on that, let's jump. Fans associated with a vehicle radiator are supposed to move air through the radiator in the same direction as air would flow when the vehicle is moving. They act with the moving air to help it move. They do not act against it. That's not smart. Fans in front of a radiator blow back through it. Fans behind a radiator "pull" air through the radiator. Think this through and it should become clear, it should make sense. It's simple physics.
You have to be more specific. Which fan? Blower motor for the heat/ac.......clutch fan for cooling.......electric fan for cooling.....? Wish I could help, if you can add more info, just send it to me on my board.
Rust and sediment can accumulate in the cooling system. Flushing the radiator helps keep the cooling system clean.
The radiator cap controls cooling system pressure.The radiator cap controls cooling system pressure.
