Why is my fan always running on my car?

The situation when the car radiator cooling fan keeps running constantly can be caused mostly by a failing coolant temperature sensor or its wiring, broken fan start relay, damage to the electrical wires, electronic engine control unit (ECU) problems.

Do I need fans on both sides of radiator?

A push/pull setup is sometimes the best way to go. Using fans on both sides of the radiator is fine but if your radiator is cooling as well as it possibly can with fans on only one side, doubling your fan count is only going to cost more money and make the whole setup louder.

How close should the fan be to the radiator?

Should I choose a pusher or pull style radiator fan?

To answer this, it seems like the consensus is in favor of the pull style fans. Independent tests have shown that even with a pusher style fan mounted only 5/8 of an inch away from the face of the radiator, there is still a vast amount of air that escapes from around the skirt between the radiator and the fan blades.
