Pusher Fans
Step 1. Attach frame mounting brackets to fan using the 4 3/4 ''self tapping screw.
Step 2. Position fan to desired location, mark holes on radiator channels or frame.
Step 3. Rotate fan blades to insure that they are free of obstruction.
Step 4. On the marked hole locations drill 13/64" holes.
Step 5. Secure the fan to radiator using the provided 1/4" x 1" self tapping screws.
Step 6. Check fan rotation.

Fan Wiring Instructions
Step 1: Locate mounting point for control
Locate a mounting point for control near inlet side of radiator. Control needs to be placed within 18"
of radiator inlet hose. You may want to mount next to radiator on fender well. Mount control using
screws provided.
Step 2: Wire the fan motors (refer to Wiring Diagram, below)
Using the bullet connectors provided, attach a length of the large diameter (12 AWG)
black
motor wires at fan. Attach a length of the large diameter (12 AWG)
black
wire to the
wires at the fan. Once the fan is in place, these will attach to the control module. If mounting the
control somewhere in the engine compartment, leave enough wire to reach the control module, but
do not connect yet.
red

red
motor
Step 3: Connect the motor wires to the control module using the female connectors provided
(Red wire to the "M+" terminal and black wire to the "M-" terminal).
Step 4: Disconnect the negative battery lead for safety while finishing the wiring. Use the large diameter red
wire to run power directly from the battery positive (+) terminal to the "B" terminal on the control module.
Connect the fuse holder in-line with this wire, as shown, but do not insert the fuse yet. Use the blue female,
ring, and butt connectors provided.
Step 5: Use the large diameter black (12 AWG) wire to run from the negative (-) battery terminal to the "G"
terminal on the control module. Use the blue female connector and ring connector provided.
Step 6: Use the small diameter red wire (14 AWG) to connect the "+" terminal on the control module to a
positive power source.
when the engine is turned off. Attach this wire to an uninterrupted (always hot) power source to allow
the fan to continue running after the engine is shut off.
(included) if necessary.
Step 7: (Optional) For air conditioning control (if desired) connect the "C" terminal on the control module to
the

Step 8: (Optional) For manual switch operation, use Flex-a-lite p/n 31148. Connect the switch as
shown on the wiring diagram (previous page). Connect the "M" terminal on the control module to the
"1" terminal on the switch. Connect the "2" terminal on the switch to a positive 12v power source.
Connect terminal "3" on the switch to a good ground (for switch illumination).
NOTE: To prevent
thermostatic activation (if only manual switch operation is desired), omit the lead to the "+"
terminal of the control box. "B", "G", "M+" and "M-" must remain connected. If not using a
Flex-a-lite manual switch, do not connect a ground wire to the switch!
Step 9: Use the zip ties provided to secure the wires and prevent them from interfering with fan
blades, belts, and pulleys in the engine compartment. Reconnect the battery and insert the fuse
provided.
Step 10: Insert the temperature probe into the radiator fins
Install temp. probe near inlet hose...
then install the insulator cap.
Locate the inlet hose from the engine to the radiator. Remove the black insulator cap and insert the
temp. probe through the radiator fins near the inlet hose. Reinstall the black insulator cap.
Step 11: Adjust the temperature control knob on the control box
If you disconnected any hoses or drained coolant to install the fan, reconnect the hoses and refill the
radiator. Press the control knob (included in wiring kit) onto the control box shaft. Turn the knob
clockwise until it stops. Start the engine and allow it to idle. Using a thermometer (positioned near
the inlet hose) or the vehicle's temperature guage, monitor the temperature. When the coolant temp.
is slightly above normal (or desired temp.), turn the knob counter-clockwise just until the fan turns on.
From now on, the fan should activate at this temperature setting. Adjust as necessary to maintain
desired temperature.
The Flex-a-lite Limited Warranty
Flex-a-lite Consolidated, 7213-45th St. Ct. E. Fife, W A 98424, T elephone No. 253-922-2700, warrant s to the original purchasing user , that all Flex-a-lite products to be free of defect s in material and
