2006 FORD F250 SUPER DUTY hood open

Vertical and horizontal aim adjustment (sealed beam headlamps)
The headlamps on your vehicle are intended to be aimed using
mechanical aimers. If mechanical aimers are used and the cross-car sight
line is in any way blocked, set the legs of the universal adaptor all to the
same setting, such that the cross-car sight line is no longer blocked, per
the instructions for the brand of mechanical aimer used. You can also
aim the headlamps visually using the procedure below.
To adjust the headlamps:
1. Park your vehicle on a level
surface about 25 feet (7.6 meters)
away from a vertical plain surface
(3). 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
• (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 (2)
for each headlamp. Adjust the aim
by turning the adjuster control
either clockwise (to adjust up) or
counterclockwise (to adjust down).
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.
8. Locate the horizontal adjuster (1) for each headlamp. Turn it clockwise
or counterclockwise, to place the left edge of the high intensity area even
with the vertical line corresponding to the headlamp under adjustment.
Vertical aim adjustment (aerodynamic headlamps)
The headlamps on your vehicle can only be vertically adjusted. Your
vehicle does not require horizontal aim adjustments.
To adjust the headlamps:
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
• (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 from the
center of your headlamp (indicated
by a 3.0 mm circle on the lens) to
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. Cover one of the
headlamps so no light hits the wall.

Replacing headlamp bulbs (aerodynamic)
1. Make sure that the headlamp control is in the OFF position and open
the hood.
2. Remove the four screws from the
top and bottom front of the
headlamp assembly.
3. Press the retaining clip at the top
of the headlamp assembly while
pulling the assembly straight out.
If removing the lamp is difficult,
removing the four screws along
the top of the grill will help
provide more clearance.
4. Disconnect the electrical
connector by squeezing the release
tab and pushing the connector
forward and then pulling it
rearward.
5. Remove the bulb assembly by
turning it counterclockwise and
pulling it straight out.
Handle a halogen headlamp bulb carefully and keep out of
children’s reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
Install the new bulb(s) in reverse order.

CHANGING THE WIPER BLADES
1. Pull the wiper arm away from the
vehicle. Turn the blade at an angle
from the wiper arm. Push the lock
pin manually to release the blade
and pull the wiper blade down
toward the windshield to remove it
from the arm.
2. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
3. Replace wiper blades at least once per year for optimum performance.
4. Poor wiper quality can be improved by cleaning the wiper blades and
the windshield; refer to Windows and wiper blades in the Cleaning
chapter.
5. To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance information for the appropriate
intervals for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park) (automatic transmission) or 1 (First) (manual transmission).
4. Open the hood. Protect yourself from engine heat.
