6. Without turning, remove the old
bulb from the lamp assembly by
pulling it straight out of the lamp
assembly.
To install the new bulb:
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.
Note: If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used.
1. With the flat side of the new bulb ’s plastic base facing upward, insert
the glass end of the bulb into the lamp assembly. Turn the bulb left or
right to align the grooves in the plastic base with the tabs in the lamp
assembly. When the grooves are aligned, push the bulb into the lamp
assembly until the plastic base contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base and lock the ring
by rotating clockwise until it snaps into place.
3. Connect the electrical connector to the bulb.
4. Install the headlamp on vehicle by aligning the lamp on the vehicle,
push rearward to fully seat the lamp assembly and install the screw on
the headlamp.
5. Push the two retainer pins down.
6. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.

3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
tightly until clicks are heard, or until it is snug.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this certification
trademark.
Use SAE 5W-20 engine oil.
Only use oils“Certified For Gasoline Engines ”by the American
Petroleum Institute (API). To protect your engine ’s warranty use
Motorcraft SAE 5W-20 or an equivalent 5W-20 oil meeting Ford
specification WSS-M2C153 –H. SAE 5W-20 oil provides optimum fuel
economy and durability performance meeting all requirements for
your vehicle ’s engine .
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil according to the appropriate schedule listed in
the scheduled maintenance guide.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
