•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
•(5) Center of headlamps
•(6) Center line of the vehicle
2. The center of the headlamp is
marked either on the lens (a circle
or cross marker) or on the bulb shield, internal to the lamp (mark or
feature). Measure the height from the center of your headlamp to the
ground (2) and mark an 8 foot (2.4 meter) long horizontal line on the
wall or screen (1) at this height (masking tape works well).
3. Turn on the low beam headlamps
and open the hood.
4. Locate the high intensity area of
the beam pattern and place the top
edge of the intensity zone even with
the horizontal reference line (4). If
the top edge of the high intensity
area is not even with the horizontal
line, follow the next step to adjust
it.
5. Locate the vertical adjuster for
each headlamp. Adjust the aim by
turning the adjuster control either
clockwise (to adjust down) or
counterclockwise (to adjust up).
6. In addition to the horizontal line
marked in step 2, a pair of vertical
lines (5) must be marked at the
center line of the headlamps on the
wall or screen.
7. On the wall or screen, locate the
high intensity area of the beam pattern. The left edge of the high
intensity area should be even with the vertical line corresponding to the
headlamp under adjustment. If the left edge of the high intensity area is
not even with the vertical line, follow the next step to adjust it.

Vertical aim adjustment (Grand Marquis only)
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away. Check your headlamp
alignment at night or in a dark area so that you can see the headlamp
beam pattern.
•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
2. Measure the height of the
headlamp bulb center from the
ground and mark an 8 foot
(2.4 meter) horizontal reference line
on the vertical wall or screen at this
height (a piece of masking tape works well).
3. Turn on the low beam headlamps to illuminate the wall or screen and
open the hood.
4. On the wall or screen you will
observe an area of high intensity
light. The top of the high intensity
area should touch the horizontal
reference line, if not, the beam will
need to be adjusted.

Headlight flashers (wig-wags) - police
An interfacing connector is provided on the headlight circuit for use of
the headlights as alternating flashers (wig-wags). The connector is
located in front of the radiator. A protective cap is attached to prevent
contaminants from entering the connector when a wig-wag module is not
installed. When installing a headlight flasher (wig-wag) module, remove
the connector and tape it to the wigwag module harness. This will ensure
that the cap is available to be reattached if the wig-wag module is
removed. For additional information, refer to theCrown Victoria
Wiring Diagram Manual.
If your vehicle is equipped with one of the optional Police Interceptor
Equipment Packages, the connector will already be used by the supplied
wig-wag module that comes with the option package.
Note:Use of the wig-wag feature overrides normal operation of the high
beam headlights, including flash-to-pass. However, the low beam
headlights will remain on and unaffected.
HEAVY-DUTY SUSPENSION - POLICE
This option includes certain heavy-duty components that contribute to
the vehicle’s stability and road handling capability under extremes of
operation. The police vehicle has a heavy duty steering gear, extra
control shock absorbers and heavy-duty front and rear stabilizer bars.
COOLERS
It is strongly recommended that auxiliary devices such as lights not be
installed at the grille. Such devices will reduce airflow through the grille
and could potentially impact the cooling system performance.
Oil cooler - police
The 4.6L engine has an engine oil cooler to maintain engine oil
temperatures.
Engine and transmission coolers
External transmission and power steering coolers are located behind the
grille and in front of the radiator. It is strongly recommended that
auxiliary devices such as lights and sirens not be installed in the air path
of these coolers as they will impact cooling system performance.
