24 Volt, universal Fit; Pt. #35024
INSTALLATION INSTRUCTIONS
REMOVAL OF EXISTING FAN AND SHROUD:
1. Make sure the engine is cool.
2. Disconnect negative (-) battery cable from battery.
3. Remove existing fan and shroud if needed.
INSTALLATION OF NEW ELECTRIC FAN SHROUD:
4. 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.
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. 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.
6. 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 an assistant hold the fan
against the core while tightening brackets.
The Flex-a-lite Limited Warranty
Flex-a-lite Consolidated, 7213-45th St. Ct. E. Fife, WA 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 work
manship 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,

WIRING INSTRUCTIONS
1. Find the thick red and black wire in the kit. Determine the length needed to connect the red and black power leads
on the VSC to the battery terminals and trim appropriately. Crimp a large yellow ring connector to the end of the
black wire and connect to the negative (-) battery terminal. Connect the other end to the black wire on the VSC
with a large butt connector (yellow sleeve).
2. Locate the fuse holder. DO NOT INSTALL THE FUSE UNTIL ALL THE WIRING IS COMPLETE. Attach a large
ring connector to one end and a yellow insulated butt connector to the other end of the fuse holder. Attach the ring
connector to the positive (+) terminal of the battery and connect the other end to the thick red wire found in the kit.
Determine the length of wire needed to reach from the fuse holder to the red wire on the VSC and trim appropriately. Use a yellow insulated butt connector to connect this wire to the red wire on the VSC. You may use the 2
small screws to mount the fuse holder if desired.
3. Find a circuit that is "hot ," preferably in a fuse box, when the key is in the "ON" position. Attach the included fuse
tap to fuse. Attach a pink female connector to one end of the thin red wire (included) and connect to fuse tap. Determine length of wire needed to reach VSC and trim to appropriate length. Attach a pink female connector to the
end of the wire and connect to terminal #9 on VSC.
4. Locate wires going to A/C clutch. Determine which wire is ground and which is positive.
Then attach supplied thin green wire by way of a piggyback connector to the positive wire
that activates clutch. Attach wire to terminal #8 on the VSC. Terminal #7 will be left open
for this application.
5. Locate temperature probe. Gently push the probe through fins in radiator as close to the
upper radiator hose as possible with ¼"-½" of the probe protruding out of the front of the
core. Install the rubber cap on the front side of the probe (if possible). This will give the
VSC the most accurate engine temperature reading. Determine length of wire needed to
reach VSC. IMPORTANT: Strip the insulation on the temperature probe wires back about
1" and fold the wire on itself to effectively double the thickness of the wire before connecting spade connectors. Then attach these wires to terminals #10 & #11. Both wires need
to be connected, but it doesn't matter which wire goes to each terminal.
6. If manual switches (Flex-a-lite #31148) have been purchased, attach them as following.
To override engine temperature to turn fans off, connect the switch to terminal #5 on VSC
to send a ground signal. To override engine temperature to turn fans on, connect the switch to terminal #6 on the
VSC so that a ground signal is sent.
Initial Set-up and Adjustment
1. Turn ignition on. After 5-6 seconds, LED #4 should light up.
If not, check to make sure that you have 12 Volts at terminal
#9 on VSC. The delay is to allow starter to start the vehicle
without the fans drawing any power.
2. With your engine running, engage the A/C. Your fans should
come on and cycle with the A/C clutch. LED's #1, 3 and 4
should be lit when fans are running. If they do not turn on,
verify that the A/C clutch is engaged and make sure that you
have the appropriate wire connected to correct terminal on
the VSC. Shut off A/C and let engine continue to idle until
you reach operating temperature.
3. Verify that operating temperature has been reached by
feeling upper radiator hose. Hot water should be flowing through hose into the radiator. Adjust the screw on the
VSC counterclockwise for a cooler setting or clockwise for a warmer setting. Once desired temperature is set, let
engine continue to idle to make sure the fans will cycle to maintain desired temperature. When fans are running,
LED's #1 and 4 should be lit.
