A/C Condenser Fan

Aftermarket & OEM A/C Condenser Fan

When a broken auxiliary fan assembly is on your vehicle, the chances the engine will overheat are almost assured. This cooling component is also referred to as the engine radiator cooling fan or just cooling fan. On older models this fan was directly attached to the water pump and turned continuously when the engine was running. Today's auxiliary fan assembly is powered by an electrical motor and is mounted to the radiator. Since it is electrical powered it is susceptible to electrical power surges and will wear out in time of being used on a vehicle. It can also burn out if debris is lodged in the fan blades stopping it from rotating.

With air conditioning as common as it is, it is amazing to think there are some kids who will never know the feeling of being stuck to a vinyl seat on a hot day. It is true that an air conditioner is not vital to make a car run or carry you from place to place but one sweltering summer day in the south and you will feel like you would almost rather have an air conditioner running than the engine. The compressor pressurizes the refrigerant necessary to create air conditioning, but another thing you need is a way to turn it from a hot gas to a neutral liquid. That is where the air conditioning condenser fan motor comes in. The fan sucks the air past the fins of the condenser core keeping them cool in order to dissipate heat. Cars may have different motors located in different places. It may be available as only a motor or may also come with a fan or an entire assembly coming with a wire harness or connector. If the air coming from the vents is not cool enough, it may be that you need a new condenser fan motor.

The auxiliary fan assembly is the device that provides the air current over the fins of the radiator so the heat from the engine can be dispersed to the surrounding air. This cooling fan is mounted to the radiator and is constructed of a rigid polymer composite material with an electrical motor at its center. The electrical motor in the auxiliary fan assembly is activated when the coolant temperature reaches a predetermined level. This device can be active when the vehicle is moving or idle like when an operator is stuck in traffic.

Packard is generally considered to be the first automaker to offer air conditioning in 1940. Many bolt-on aftermarket companies offered air conditioning, and some original equipment manufacturers offered them throughout the fifties and sixties but they tended to be rare options mainly due to cost. By the 1970s, more vehicles were having air conditioners engineered into part of the car and for the last 30 years or so it has been rare to find a new vehicle that does not offer air conditioning. There has always been a need to transform the compressed refrigerant into a liquid and the condenser fan motor has always done that. The fans are typically mounted behind the radiator and electrically powered. The condenser fan motor turns on when you turn on your A/C, and it cools the refrigerant as it passes through the condenser core before going to the expansion valve.

The replacement procedure for the auxiliary fan assembly requires that the engine be off and cooled down along with the battery being disconnected. The electrical plug to the fan's motor has to be disconnected before the mounting screws for the fan's frame are removed. Care has to be taken when removing the auxiliary fan assembly from the engine compartment so the fins and the tubes in the radiator are not damaged that could cause a coolant leak. Any debris in the radiator should be cleaned away by hand or a water hose.

Seek out a qualified mechanic to change out your air conditioning condenser fan motor but it is usually pretty simple to change. Changing the part varies from vehicle to vehicle but we have a bullet-pointed list below just showing some basic instructions of how this part may be changed.

  • Find the location of the condenser core in the car. It is usually in front of the radiator.
  • Disconnect the plug and wiring from the fan assembly, and then unscrew it from the radiator core.
  • Remove the old motor and replace it with the new one checking to make sure that they both match.
  • Place the new condenser fan motor into the assembly. Screw the whole assembly back into place.
  • Reconnect the plug and the wiring.
  • Test the motor by turning the A/C on and off once every couple of minutes to make sure that is working properly.
