Fig. Fig. 3: Remove the retaining screws (A), but do not loosen the adjusting screws (B)

  1. Unscrew the headlight bezel (1971-77) or headlight grille (1978-81) retaining screws. Remove the bezel or grille.
  2.  
  3. Loosen, but do not remove, the three headlight retaining ring screws, on 1971-79 models, rotate the ring counterclockwise to remove it.
  4.  

Do not mistake the adjusting screws for the retaining ring screws. There are only two adjusting screws for each headlight. They are located right next to the top and the side retaining ring screws. Turning these screws will result in improper headlight adjustment.

  1. On models with square headlights (1980-81), remove the four headlight retaining ring screws and then remove the ring.
  2.  
  3. Pull the headlight away from its positioning ring slightly and unplug the electrical connection at its rear.
  4.  
  5. Remove the headlight.
  6.  
  7. Installation is in the reverse order of removal.
  8.  

Do not interchange the inner and outer headlights.

  1. Raise the headlight by twisting the headlight switch in the first click stop.
  2.  
  3. Disconnect the pink fusible link at the battery.
  4.  


CAUTION
Unless power is disconnected, the headlights could suddenly retract and cause personal injury.

  1. Remove the ornament and the beam unit retaining screws, ring and partially remove the sealed beam unit.
  2.  
  3. Compress the lock releases and disconnect the wire connector behind the beam unit. Remove the beam unit completely.
  4.  

If the wire connector is tight, wiggle it while holding in the lock releases and pulling out.

  1. Installation is in the reverse order of removal. Install the beam unit with the single protrusion on the glass face-up. Use only a beam unit with the same number and wattage-regular sealed beam units are 65/55 watts, and halogen units are either 65/55 or 65/35 watts. Reconnect the fusible link, and check headlight aim.
  2.  

AIMING



On 1971-79 models there are two adjusting screws for each headlight. The vertical adjustment screw is located at the top of the headlight, next to the retaining ring screw. The horizontal adjustment screw is located on the side of the headlight, also next to the retaining ring screw. On 1980-81 models, the two adjusting screws are found on the top and on the side of the headlight. They can each be found in a recess in the retaining ring. As with the earlier models, the top screw is for the vertical adjustments and side screw is for the horizontal adjustment. On 1982-85 models, the two adjusting screws are found on the bottom and on the side of the headlight. The bottom screw is for vertical adjustments and the side screw is for horizontal adjustment.

The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim, and adjusted if necessary, after installing a new sealed beam unit or if the front end sheet metal has been replaced. The headlamps should be aimed by a professional with a special alignment tool. Certain state and local authorities may vary this procedure, but use the procedure below for temporary adjustments.

The vehicle's fuel tank should be about half full when adjusting the headlights. Tires should be properly inflated, and if a heavy load is carried in the trunk it should remain there.

  1. Remove the headlight bezel or grille.
  2.  
  3. Place the car on a level floor with headlamps 25 ft. from a light colored wall.
  4.  
  5. Tape three vertical lines on the wall, one for the vertical center of the car and two for the vertical center of the headlamps. Then, tape one horizontal line for the horizontal and vertical center of the headlamps.
  6.  
  7. Adjust the low beams so the high intensity zone is just below the horizontal line and to the right of the outboard vertical lines.
  8.  
  9. Adjust the high beams so the high intensity zone is centered where the outboard lines intersect with the horizontal line.
