Tools Required:
- Socket Wrench Set
- Drill or Screwdrivers
- Wire Cutters
- Wire Strippers
- Wire Crimping Tool
- Thread Sealer
- Silicon
Installation Instructions
- Remove the negative battery cable
- Remove the radiator cover
- Remove the 2 bolts securing the fan shroud to the radiator
- Loosen the 4 bolts on the water pump securing the clutch fan
- Release the tension on the belt
- Push the fan towards the radiator carefully to free it from the water pump shaft
- Pull the fan shroud up, position it out of the way, and remove the clutch fan from the car.
- Disconnect the overflow tank line from the top of the radiator, and remove the fan shroud from the car
- Drain about a gallon of coolant from the radiator
- Loosen the hose clamp on the upper radiator hose, and remove the hose from the thermostat housing
- Remove the hose clamp securing the bypass hose to the water pump, and thermostat housing
- Remove the 2 thermostat housing to intake manifold bolts
- Remove the thermostat hose, and housing
- Take this time to clean the intake manifold
- Apply thread sealer to the included temperature probe, and thread it into the 5.0 Resto thermostat housing, and carefully tighten the probe with a 3/4" wrench
- Use a new thermostat, and lightly dab 3 small dots of the silicone onto the housing
- Make sure the bleed hole is towards the top, and at the 12 O'Clock position
- Apply a few small dabs of silicone to the gasket, and center the gasket on the housing
- Position the thermostat housing back into place, and use the included exclusive 5.0 Resto hardware to secure it to the manifold
- Torque the bolts to 13-1/2 lb ft.
- Reposition the bypass hose, and tighten the clamps
- Run the temperature probe wire, along the plugwire, and out of the way for now
- Position the new fan shroud into place
- Tighten down the hardware securing the fan shroud to the radiator
- Plug the main harness for the electric fan into the controller
- Plug in the relay, and use the included screws to secure it to the shroud
- For added safety, we added a 30 amp, in-line fuse to the 3 ft. free floating red power wire included in the kit
- If you go this route, use a butt connector to join the single 3 foot wire and a ring terminal on the other side of the fuse wire, which will go to the starter solenoid
- If you don't go this route, simply splice the ring terminal on the end of the 3 ft. single red wire included in the kit
- Loosen the nut on the battery side of the solenoid, and slide the ring terminal over the stud, and re-tighten the nut. Your alternate connection will be that you can connect this directly to the battery.
- Use another included ring terminal for the black wire, on the harness and ground it to the headlight ground by the battery
- Plug in the temperature probe
- Secure the fan harness to the blade covers, and cut the preinstalled connectors
- Splice the wires, and twist them together
- Make sure blue is with blue, and black is with black
- Use a butt connector to splice the color coded wires
- The red wire from the controller will go with the black wire from the fans
- The red 3 foot wire will go with the blue wires from the fans
- Use the included quick-crimp to splice the green wire from the controller, to the yellow A/C Wire
- Quick-crimp the yellow wire from the controller, to the a 12 volt ignition source. This can be found on various locations on the car.
- Tidy up the wiring, and then mount the included overflow tank wherever you would like
- Then run your overflow hose to your overflow tank, from the radiator
- Before starting up, and testing for operation be sure to replace the coolant that you drained out in the beginning of the install
- Drive the car around the block a few times to get it to operating temperature, and get out and check the fans
- At this point if you want to change the temperature turn-on setting, simply remove the rubber plug on the controller, and use a flat head screwdriver to make your adjustments
- Double check your work, and you're all done!
