Step 1: Remove Existing Fan & Shroud
Tip: If your vehicle is equipped with a 2-piece shroud, it is usually easiest to remove the shroud first, then remove the fan blade/clutch. If a one-piece shroud, it is sometimes necessary to lift out the shroud and blade together.

The Flex-a-lite Limited Warranty
Flex-a-lite Consolidated, 7213-45th St. Ct. E. Fife, W A 98424, Telephone No. 253-922-2700, warrants to the original purchasing user, that all Flex-a-lite products to be free of defects in material and workmanship for a period of 365 days (1 year) from date of purchase. Flex-a-lite products failing within 365 days (1 year) from date of purchase may be returned to the factory through the point of purchase, transportation charges prepaid. If, on inspection, cause of failure is determined to be defective material or workmanship and not by misuse, accidental or improper installation, Flex-a-lite will replace the fan free of charge, transportation prepaid. Flex-a-lite will not be liable for incidental, progressive or consequential damages. Some states do not allow the exclusion or limit ation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal right s and you may have other rights, which vary from state to state. The Flex-a-lite warranty is in compliance with the Magnuson-Moss Warranty Act of 1975.
and shroud.
Step 2: Check Fit of New Fan Assembly
Hold, or have a friend hold the fan in place while checking for possible obstructions that may interfere with the blades or shroud. It may be necessary to move or tie back small hoses or wires. If the fan does not fit at this point, additional modifications or a different Flex-a-lite fan may be required.

test-fit and check for obstructions.
The fan control module (included) can be mounted to any flat surface near the fan, or can be mounted to the fan shroud. Mark the 2 hole locations on the mounting surface, then drill 3/16" holes and use the self-tapping bolts provided to mount the module.
If necessary , drill two 3/16" holes... and mount control module in desired location.
Step 4: Wire the fan motors (refer to Wiring Diagram, next page)
Using the yellow butt connectors provided, attach a length of the large diameter (10 AWG) to the

Step 5: Mount the fan assembly to the radiator
Look for at least four potential mounting points that are able to support the weight of the fan to attach the fan to the vehicle. Cross braces, radiator trays, front facia, and radiator mounting points are all possible mounting points. Use the universal brackets and hardware kit supplied to hold the fan against the radiator core. On some applications, the brackets may need to be cut or modified to fit. Additional holes may need to be drilled as well.
Put the fan into place. Before tightening the brack­ets, adjust the fan so that the rubber seal is contact­ing the radiator core and compress the seal about 50%. It may help to have a friend hold the fan against the core while tightening brackets.

The brackets can be cut to length if necessary.
Compress seal against core and tighten in place.
Step 6: Wire the control module

6a. Connect the motor wires to the control module (Red wire to the "M+" terminal and black wire to the "M-" terminal).
6b. Disconnect the negative battery lead for safety while finishing the wiring. Use the large diameter red (10 AWG) 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 yellow female, ring, and butt connectors provided.

6c. Use the large diameter black (10 AWG) wire to run from the negative (-) battery terminal to the "G" terminal on the control module. Use the yellow female connector and ring connector provided.
6d. Use the small diameter red wire (14 AWG) to connect the "+" terminal on the control module to a positive power source.
NOTE: Attaching this wire to an ignition-controlled source will shut off the fan 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.

wire that triggers the A/C compressor using the small diameter green (14
positive
trigger wire. Use the 3-way connector (included) to tap into this wire and send a signal to the fan control module. The fan will cycle on and off with the A/C clutch when the A/C is turned on.
6f. (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!
6g. 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 7: Insert the temperature probe into the radiator fins (Does not apply to #188)
Install temp. probe near inlet hose...
then replace 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 8: 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 hand held 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.
