An electric fan can be a great addition to any cooling system or may even be the main cooling source for the radiator. With so many late model engines and serpentine belt systems being installed in the Classics, there is often no room for a water fan. In this case, an electric fan is the only way to go. Or your engine fan won't quite move enough air to keep your engine cool while idling around town or maybe your AC needs additional airflow to cool better.
The fan can be mounted on the backside of the radiator to air through the radiator core or mounted on the front side to assist in forcing air through the radiator core and, in turn, keep the engine cooler. The fan or fans can be wired to come on with the key, with a temperature sender, or even when the AC is turned on.
Time Frame: 1 hour

An electric fan is much more efficient when it's air through the radiator core. When the air through, you will get some CFM loss due to deflection from the radiator core. With the radiator in the V8 (behind the core support) there is usually about 34" between the fan blade and radiator core on a short water small block. This makes it impossible to install an electric fan on the back side of the radiator to supplement or replace the engine fan.

To mount an electric fan on the back side of the radiator, the radiator must be in the 6-cylinder (in front of the core support). A 6-cylinder radiator and 6-cylinder core support maybe used or a V8 radiator can be relocated to the 6-cylinder and still use the V8 core support using relocation kit PIN: 57-132134-1

With the radiator in the 6-cylinder, there will be 4" between the fan and radiator core. Now there is of room to remove the engine fan and install an electric fan.

The electric fan has four separate mounting tabs that key into the electric fan body.

The electric fan is mounted to the radiator core using the supplied kit. The kit includes four foam rubber for and four on retaining clips. This mounting system is simple and eliminates unsightly brackets that block airflow.
Image 6a, 6b:
The foam rubber have adhesive sides that are on the mounting tabs of the electric fan.
Image 7a, 7b:
Place the electric fan in the desired location and install the through the fan mounting tabs and through the radiator core
Image 8a, 8b, 8c, 8d, 8e:
Install the retaining clips onto the on the back side of the core and tight. Now cut off the excess and the mounting is done.

You may wish to install your electric fan on the front of the radiator or AC condenser for additional cooling. This will keep the condenser cooler and help the NC system be more efficient. This can be used in conjunction with a water-driven fan blade or with an electric fan on the engine side of the radiator.

The electric fan has a black and red wire. If the fan is going to be used as a fan (behind the radiator), the BLACK wire would connect to a good ground and the RED wire would connect to an ignition-on 12-volt source. If the fan is going to be used as a fan (in front of the core support), the RED wire would connect to a good ground and the BLACK wire would connect to the ignition-on 12-volt source. The fan can simply be wired to the ignition switch so the fan will come on when the key is on. The fan can also be wired through a temperature sender PIN 57-132663-1 that will turn the fan on and off at about 190 degrees. This sender should always be installed in the engine and not the radiator tank to assure an accurate temperature reading. If the fan is going to be installed on the AC condenser to help cool the condenser, a trinary switch can be used in the AC liquid line that will turn the fan on when the AC is activated.

The fan blade itself will need to be reversed if the fan is going to be used as a fan. The fan blade is held to the motor with a 7/16" right-hand locking nut. Remove the nut, flip the fan blade over, and tighten the nut back down. With the addition of an electric fan, the car will run cooler, the AC will be more efficient, and you won't be staring at worrying about the temperature gauge anymore!
