CHANGING THE ENGINE AIR
FILTER - 2.3L ECOBOOST™/
5.0L WARNING: To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: Failure to use the correct air filter
element may result in severe engine
damage. Your warranty may not cover
these damages.
Only use the specified replacement air
filter. See
Motorcraft Parts (page 295).
For EcoBoost equipped vehicles: When
servicing the air cleaner, it is important that
no foreign material enter the air induction
system. The engine and turbocharger are
susceptible to damage from even small
particles.
Change the air filter element at the proper
intervals. See
Scheduled Maintenance
(page 422).

the air filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the
air filter housing.

WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your
vehicle in a shaded area out of direct
sunlight. Always wash your vehicle before
applying wax.
•
Use a quality wax that does not contain
abrasives.
• Follow the manufacturer ’s instructions
to apply and remove the wax.
• Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact
with any non-body (low-gloss black)
colored trim. The wax will discolor or
stain the parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should
feel smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal. When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
Note: If your vehicle has an engine cover
remove the cover before application of
Motorcraft Engine Shampoo and Degreaser.
Immediately rinse away any over spray.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.

•
Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Engine
• Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting. Note:
It is necessary to reset memory
features if battery cables are disconnected.
Brakes
• Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
