ADJUSTABLE FAN CONTROL INSTALLATION INSTRUCTIONS CONTROL BOX MOUNTING: NOTE: The control box must be mounted to allow access to the temperature adjusting screw and keep control away lrom high heat sources. such as exhaust monitolds or pipes. I. Control Box to Fun Bracket Mounting (Does not apply to Thin Line Models 367037l0): A. Insert white plastic rivets through holes in control box tabs. B. Place control box in ion bracket C. Align rivets with holes in bracket. Press Into holes. D. Use punch and light hammer to tap rivet center llush with rivet. 2, Other Mounting Locations: A. Drill two 3/16" holes 2-1/8" apart through mounting surface. B. Use plastic rivets or sheet metal screws to attach control to the mounting location.

Attach the red ware to the positive terminal at the automobile battery, Use the ring terminal lrom the parts lrit GREY 0! BLACK 2. Black wire (ground) ~ Attach the control box black wire to any good ground. Use the lork terminal lrom the parts lrit. 3. Yellow wire (ignition signal) - Attach the yellow wire to a positive (+) I2 volt connectan that is controlled by the i nition. To allow tan(s) to operate with the ignition all, connect the yel ow wire to a constantly live (hot) lead. CAUTION: Relay damage will occur it the yellow wire is connected to a source with low or uctuating voltage. This will occur on some electronic i nition systems or coils that use a ballast resistor to drop voltage to tie (oil. This condition will cause the relay to chatter. It this occurs, conned the yellow wire to another lead which is not on the engine ignitior. circuit. A. Green wire (Air conditioner override) - Use the blue slicer connector, attach the great wire to the A/ C Clutch wire. It the automobile does not GROUNDT have air canditoning, tie all or cut short the green wire. 5. Orange lusetl wire (power output) - Attach the orange tused wire to the tan power wire. Ground the remaining tan motor wire. FOR FAN MODELS gag-3659: Reter to the instructions included in those kits to determine the power wire. FOR THINLINE FAN MODELS 3670-3710: Rater to the n. :rrnation label on the shroud to determine the power wire, 6. Blue Wire (power output) Used tor dual (an installation.

PROBLEM CHART I POSSIBLE CAUSE the remaining lan SOLUTION INSTALLATION TESTING: I. It vehicle is equipped with air conditioning, turn ignition key to ON posrtion. Do Not start engine. Turn on A/C, tan(s) should start operating. Turn Oil A/ C, and tan(s) should stop operating. 2. Mark position at adjustment pot located on top at control unit, Control is reset at I60F. Range oi ad'ustment is 90 - 2I0F. Turn the arliustment screw clockwise until it stops. DO NOT FORCE PAST STOP. 3/4 TURN is the lull range at adjustment. Turning Clockwise will raise the temperature, counter clockwise will lower the temperature. Start the engine and allow it to warmrup. 3. Feel inlet side at the radiator. When the thermostat opens and the radiator begins to heat up, turn the adjusting screw counter clockwise until the tan(s) engage. Turn na turther. Fan(s) are now properly adjusted.

ELECTRIC FAN TROUBLESHOOTING: (See chart I) PROBE, CONTROL, RELAY TESTING Probe: Carelully cut through the insu'otion on the grey wires at the thermal probe. With the ignition on, make contact across the wires Relay should close and turn on tanls, Testin probe: Cut both probe wires and strip back the insulation. Use an mmeter to measure resistance across the probe. It should be in the range at 40K - 50K ohms at 70 - 80F. Resistance should decrease as tern ature increases. Intijiite resistance indicates an open circuit. Very ow resistance indicates a 5 art. Control: With the ignition on remove relay. Check tor H 2 volts at terminal 85 on relay socket. It it is not "hot", check yellow wire for +I 2 volts. It yellow wire is "hot" and terminal 85 is not, then control box is detective. Relay: Pull the relay partially out at the socket to allow access to relay terminals. With the ignition on, engine NOT running, connect a jumper wire tram terminal 86 to ground. The relay should click (close). and the tan(s) should turn on. it tank) do no turn on, then the relay may be delective. Check red power supply wire tor +I2 volts.

INSTALACION DEL SENSOR DE TEMPERATURA: (FIGURA I) Nola: Escoja el sitio de montaje del sensor antes de instalar el ventilodor. La instolacion del sensor requiere acceso por los dos lados del radiador. En caso necesario, retire el radiador y/o el condensador de aire acondicionado para permitir el acceso a ambos lados. i.
