Fan Housing Removal

(Engine IN the car.)

~~~

Note: The fan housing CAN be removed from the car without removing the engine -- to replace the cooling vanes, for instance. The procedure for removing the fan housing with the engine in the car is as follows:

  1. Remove the drive belt as follows -
    1. The front half of the alternator pulley has two cut-out slots in it. Inserting a thin screw driver in either slot locks the pulley so you can loosen/tighten the 19mm retaining nut. Remove the retaining nut on the alternator shaft with the 19mm wrench, then slip off the washer, any spare shims, and the outer pulley half. Take note of how many shims are between the pulley halves so you can easily re-tension the pulley on reassembly.
    2. Slip the belt off the crankshaft pulley and remove it.
    3. Remove the inner pulley half, being careful to remove the Woodruff key and stow it and the shims and nut in a baggie in a safe place.

  2. Remove the air cleaner.
  3. Detach the accelerator cable from the throttle lever and remove the fuel line from the fuel pump to the carburetor.
  4. Remove the carburetor.
  5. Pull out the accelerator cable guide tube and pull the accelerator cable forward, out of the fan housing.
  6. Remove the cable from the negative terminal of the battery.
  7. Label and then detach the electrical connectors from the alternator.
  8. Remove the strap that holds the alternator to the support.
  9. Disconnect the ignition cable from the coil and the fresh air tubes on either side of the fan housing. Disconnect the spark plug wires from the attachments in the fan housing (three places).
  10. Remove the hood and the hood hinge brackets. You must remove the brackets to get enough clearance to lift the fan shroud.
  11. On the left side of the car, reach down in front (front) of the fan housing with a 10mm box-end wrench (ring spanner) and remove the bolt for the oil cooler cover and the bolt that holds the fan housing to the oil cooler flange. This is awkward and you'll be working largely by feel.
  12. Note: If these two connectors are cheese-head screws, replace them with 10-mm hex-head bolts. This will save you lots of trouble reinstalling them and removing them next time (10-mm open-end wrench (ring spanner) instead of an offset screwdriver.

  13. Remove the oil cooler cover and the air duct.
  14. Unbolt the thermostat and unscrew the thermostat from its rod.
  15. Disconnect and remove the connecting link between the cooling flaps in front of the fan housing (don't lose the spring).
  16. Remove the two bolts on either side of the fan housing. The one on the left also supports the metal fuel line, and you may need to disconnect this line from the fuel pump to move it out of the way.
  17. Carefully raise the fan housing and remove it from the car. At this point you can remove the four mounting bolts from the outer fan cover on the rear of the shroud; this will allow the alternator/fan assembly to be removed.
