STANDARD PROCEDURE - HEADLAMP UNIT
ALIGNMENT - EXPORT
VEHICLE PREPARATION FOR HEADLAMP UNIT
ALIGNMENT
(1) Verify the headlamp switch is in the low beam
setting.
(2) If the vehicle is equipped with a headlamp lev-
eling system, be certain the headlamp leveling switch
is in the "0" position.
(3) Correct defective components that could hinder
proper headlamp alignment.
(4) Verify proper tire inflation.
(5) Clean headlamp lenses.
(6) Verify that luggage area is loaded as the vehi-
cle is routinely used.
(7) Fuel tank should be FULL. Add 2.94 kg (6.5
lbs.) of weight over the fuel tank for each estimated
gallon of missing fuel.
ALIGNMENT SCREEN PREPARATION FOR
HEADLAMP UNIT ALIGNMENT
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 10 meters (32.8 ft) away from front
of headlamp lens.
(2) If necessary, tape a line on the floor 10 meters
(32.8 ft) away from and parallel to the wall.
(3) Place 75 kg in the drivers seat to simulate the
ride height of the vehicle when driven.
(4) Measure from the floor up 1.27 meters (5 ft)
and tape a line on the wall at the centerline of the
vehicle (Fig. 34). Sight along the centerline of the
vehicle (from rear of vehicle forward) to verify accu-
racy of the line placement.
(5) Rock vehicle side-to-side three times to allow
suspension to stabilize.
(6) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(7) Measure the distance from the center of head-
lamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for
up/down adjustment reference (this should be 623
mm (24.5 in.).
(8) Place a tape line 100 mm (4 in.) below and par-
allel to the center of headlamp line (Fig. 34).
(9) Measure distance from the centerline of the
vehicle to the center of each headlamp unit being
aligned. Transfer measurements to screen (with tape)
to each side of vehicle centerline. Use these lines for
left/right adjustment reference (this should be 1338.5
mm (52.7 in.) ).
LAMPS/LIGHTING - EXTERIOR 8L - 29
HEADLAMP UNIT ADJUSTMENT
A properly aimed low beam headlamp will project a
high intensity light pattern on the screen with the
horizontal cut-off line aligned with the tape line 100
mm (4 in.) below the headlamp centerline (Fig. 34).
The intersection of the horizontal and 15 degree cut-
off lines in the projected pattern should align to the
intersection of the headlamp centerline vertical tape
line and the tape line 100 mm (4 in.) below the head-
lamp horizontal centerline.
NOTE: The vehicles low beam headlamps must be
ON during the headlamp alignment procedure. The
high beam pattern will be correct when the low
beams are aligned properly.
NOTE: The headlamp leveling switch must be in the
"0" position. Failure to do so will result in improp-
erly adjusted headlamps.
To adjust headlamp unit alignment, rotate align-
ment screws to achieve the specified low beam hot
spot pattern (Fig. 34).

REMOVAL

NOTE: Some moisture accumulation inside a vented
headlamp unit is normal. Moisture will vent from
tubes or vents located on the back of the unit. This
normal condition will appear as a fogging on the
inside of the headlamp lens (similar to the fog that
sometimes appears on the inside of the wind-
shield). This moisture may be removed by activat-
ing the headlamps on high beam for 15 minutes.
If water droplets larger than 1 mm in size have
accumulated on the inside of the headlamp lens,
the headlamp unit should be replaced.
CONCORDE/300M
(1) Release hood latch and open hood.
(2) Disconnect and isolate the battery negative
remote cable.
(3) Remove the one bolt retaining the washer bot-
tle filler neck and move aside.
(4) Remove the two bolts retaining the speed con-
trol servo and move aside.
(5) Remove fasteners to upper radiator crossmem-
ber:
• Two jack screws on each side.
• Three crossmember retaining bolts on each side.
• Three push pin fasteners across top of grille.
