REMOVAL & INSTALLATION
Sealed Beam Type
See Figure 1
- Unfasten the headlight door mounted screws and pull the headlight forward.
- Unplug the parking lamp socket and remove the headlight door.
- Unfasten the retainer ring screws and remove the retainer ring.
- Pull the headlight forward and unplug the headlight electrical connector.
- Remove the headlight assembly.
- Attach the headlight electrical connector.
- Place the headlight into position making sure to align the headlight glass tabs into the positioning slots.
- Install the retainer ring and tighten the retaining screws.
Remove the double sided tape on the outer edge of the headlight door and replace with new tape before installing the door.
- Attach the parking lamp socket to the parking lamp.
- Install the headlight door and tighten the retaining screws.
- Turn the headlights on and check for proper operation.
- Adjust and aim the headlights as necessary.
See Figures 2 and 3
The replaceable halogen headlamp bulb contains gas under pressure. The bulb may shatter if the glass envelope is scratched or the bulb is dropped. Handle the bulb carefully. Grasp the bulb ONLY by its plastic base. Do not touch the glass as deposits left by your fingers will cause hot spots when the bulb is illumined which may cause it to prematurely fail. Keep the bulb out of the reach of children.
- Check to see that the headlight switch is in the OFF position.
- Raise the hood and locate the bulb installed in the rear of the headlight body.
- Unplug the electrical connector by depressing the locktab and pulling the connector rearward.
- Remove the bulb retaining ring by rotating it counterclockwise (when viewed from the rear) about 1 / 8 of a turn, then slide the ring off the plastic base.
Keep the bulb retaining ring, it will be reused with the new bulb.
- Carefully remove the headlight bulb from its socket in the reflector by gently pulling it straight backward out of the socket. Do not rotate the bulb while removing it.
- With the flat side of the plastic base of the bulb facing upward, insert the glass envelope of the bulb into the socket. Turn the base slightly to the left or right, if necessary, to align the grooves in the forward part of the plastic base with the corresponding locating tabs inside the socket. When the grooves are aligned, push the bulb firmly into the socket until the mounting flange on the base contacts the rear face of the socket.
- Slip the bulb retaining ring over the rear of the plastic base against the mounting flange. Lock the ring into the socket by rotating the ring clockwise. A stop will be felt when the retaining ring is fully engaged.
- Push the electrical connector into the rear of the plastic until it snaps and locks into position.
- Turn the headlights on and check for proper operation.
AIMING THE HEADLIGHTS
See Figures 4, 5, 6, 7 and 8
The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim and adjusted as necessary. Certain state and local authorities have requirements for headlight aiming; these should be checked before adjustment is made.
Headlight adjustment may be temporarily made using a wall, as described below, or on the rear of another vehicle. When adjusted, the lights should not glare in oncoming car or truck windshields, nor should they illuminate the passenger compartment of vehicles driving in front of you. These adjustments are rough and should always be fine-tuned by a repair shop which is equipped with headlight aiming tools. Improper adjustments may be both dangerous and illegal.
For most of the vehicles covered by this guide, horizontal and vertical aiming of each sealed beam unit is provided by two adjusting screws which move the retaining ring and adjusting plate against the tension of a coil spring. There is no adjustment for focus; this is done during headlight manufacturing.
Because the composite headlight assembly is bolted into position, no adjustment should be necessary or possible. Some applications, however, may be bolted to an adjuster plate or may be retained by adjusting screws. If so, follow this procedure when adjusting the lights, BUT always have the adjustment checked by a reputable shop.
Before removing the headlight bulb or disturbing the headlamp in any way, note the current settings in order to ease headlight adjustment upon reassembly. If the high or low beam setting of the old lamp still works, this can be done using the wall of a garage or a building:
- Park the vehicle on a level surface, with the fuel tank about 1 / 2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall.
- If aiming is to be performed outdoors, it is advisable to wait until dusk in order to properly see the headlight beams on the wall. If done in a garage, darken the area around the wall as much as possible by closing shades or hanging cloth over the windows.
- Turn the headlights ON and mark the wall at the center of each light's low beam, then switch on the brights and mark the center of each light's high beam. A short length of masking tape which is visible from the front of the vehicle may be used. Although marking all four positions is advisable, marking one position from each light should be sufficient.
- If neither beam on one side is working, and if another like-sized vehicle is available, park the second one in the exact spot where the vehicle was and mark the beams using the same-side light. Then switch the vehicles so the one to be aimed is back in the original spot. It must be parked no closer to or farther away from the wall than the second vehicle.
- Perform any necessary repairs, but make sure the vehicle is not moved, or is returned to the exact spot from which the lights were marked. Turn the headlights ON and adjust the beams to match the marks on the wall.
- Have the headlight adjustment checked as soon as possible by a reputable repair shop.
