Through Core Mounting Instructions

(SEE DIAGRAM “A”)

1.Position the electric fan against the front of the
radiator , and mark location of the holes on radiator .(Some

applications may have A/C condensers and/or tranny
coolers on the front of the radiator. Additional adjust­ments or modifications may be necessary for installation)

2. Holding fan in position, rotate fan blades to make sure
they are free of obstructions.

3. With a small Phillips screwdriver pass through the
marked holes, carefully spread the fins to allow easy pas­sage for the nylon bolts (4 for the single fan unit, 6 for the
double fan unit). Pass the bolts through the shroud holes
then twist the bolts through the radiator . Note: Be sure to

pass through the motor lead connectors when inserting the
bolt through the top middle hole of the double unit. See
expanded view on diagram B.

4. Slide the rubber washer , then the steel washer onto the nylon bolt and
finger tighten wing nuts until snug.

5. Once again, rotate fan blades to insure that they are free of obstruction.

1. Attach frame mounting brackets to fan using
nylon bolts, cut them to 1", using wing nuts to
secure. Note: Be sure to pass through the motor lead

connectors when inserting the bolt through the top
middle hole of the double unit. See expanded view
on diagram B.

2. Position fan to desired location, mark holes on
radiator channels or frame.

3. Rotate fan blades to insure that they are free of
obstruction.

4. On the marked hole locations drill 13/64" holes.

5. Secure the fan to radiator using the provided
1/4" x 1" self tapping screws.

6. Once again, rotate fan blades to insure that they
are free of obstruction.

1. Disconnect battery .

2. Attach black motor wire(s) to M+.

3. Attach white motor wire(s) to M-.

4. Connect the “+” terminal to a 12 volt positive (+)
power source, e.g. fuse box. Use the wire provided in
the kit.Note: To stop the fan unit from operating when

the vehicle is shut off, attach this wire to an ignition
switched 12 volt power source.

5. Connect the “B” terminal to a 12 volt positive (+)
power source, e.g. Positive side of battery , or alter­nator . Use the wire and inline fuse provided in the
kit.

6. If you have air conditioning: Connect the “C”
terminal to the positive(+) side of the air conditioning
