ENGINE OIL DIPSTICKA.–MIN
B. – MAX
ENGINE OIL CHECK
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 15 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).
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the engine oil level dipstick. See the
Under Hood Overview in this chapter for location of dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, then remove it again.
If the oil level is between the lower and upper holes or between the MIN
and MAX marks (depending on application), the oil level is acceptable.
DO NOT ADD OIL.
If the oil level is below the lower hole or the MIN mark, add enough oil
to raise the level within the lower and upper holes or within the
MIN-MAX range.
Oil levels above the upper hole or the MAX mark may cause engine
damage. Some oil must be removed from the engine by an authorized
dealer.
7. Put the dipstick back in and ensure it is fully seated.
Adding Engine Oil
Note: Do not remove the engine oil level dipstick or the filler cap when
the engine is running.

Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine and
emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Check the engine oil level.
2. If the engine oil level is not within the normal range, add engine oil
that meets Ford specifications. See Capacities and Specificationsfor
more information. Remove the engine oil filler cap and use a funnel to
pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level dipstick.
4. Install the dipstick and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks are heard or until the cap is fully seated.
ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the concentration and level of the engine
coolant at the intervals listed in the Scheduled Maintenance
Information.
Note: Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note: If the level is at the MIN mark, below the MIN mark, or empty,
add coolant immediately. See Adding Engine Coolantin this chapter.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.

•Spray Motorcraft Engine Shampoo and Degreaser on all parts that
require cleaning and pressure rinse clean. In Canada, use Motorcraft
Engine Shampoo.
• 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
The windows and wiper blades should be cleaned regularly. If the wipers
do not wipe properly, substances on the vehicle’s glass or the wiper
blades may cause squeaking or chatter noise from the blades, and
streaking and smearing of the windshield. To clean these items, follow
these tips:
• The windows may be cleaned with a non-abrasive cleaner such as
Motorcraft® Ultra-Clear Spray Glass Cleaner (U.S.) or Motorcraft
Premium Glass Cleaner (Canada).
• The wiper blades can be cleaned with isopropyl (rubbing) alcohol or
Motorcraft Premium Windshield Washer Concentrates in the U.S., or
Motorcraft Premium Quality Windshield Washer Fluid in Canada.
Replace your wiper blades when they appear worn or do not function
properly.
• Do not use abrasive materials, as they may cause scratches.
• Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.
Note: Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause damage
to the rear window defroster’s heated grid lines.

Note:Follow the same procedure as cleaning leather seats for cleaning
leather instrument panels and leather interior trim surfaces. See
Cleaning Leather Seats in this chapter.
Clean the instrument panel and cluster lens with a clean, damp, white,
cotton cloth, then use a clean and dry, white, cotton cloth to dry these
areas.
• Avoid cleaners or polishes that increase the gloss of the upper portion
of the instrument panel. The dull finish in this area helps protect the
driver from undesirable windshield reflection.
• Be certain to wash or wipe your hands clean if you have been in
contact with certain products, such as insect repellent and suntan
lotion, in order to avoid possible damage to the interior painted
surfaces.
• Do not use household or glass cleaners as these may damage the
finish of the instrument panel, interior trim and cluster lens.
• Do not allow air fresheners and hand sanitizers to spill on interior
surfaces. If a spill occurs, wipe off immediately. Damage may not be
covered by your warranty.
If a staining liquid like coffee or juice has been spilled on the instrument
panel or on interior trim surfaces, clean as follows:
1. Wipe up spilled liquid using a clean, white, cotton cloth.
2. Use Motorcraft Premium Leather and Vinyl Cleaner or a commercially
available leather cleaning product for automotive interiors. Test any
cleaner or stain remover on an inconspicuous area.
3. Alternatively, wipe the surface with a damp, clean, white, cotton cloth
and a mild soap and water solution. Dry the area with a clean, soft cloth.
4. If necessary, apply more soap and water solution or cleaning product
to a clean, white, cotton cloth and press the cloth onto the soiled area.
Allow this to set at room temperature for 30 minutes.
5. Remove the soaked cloth, then with a clean, damp cloth, use a rubbing
motion for 60 seconds on the soiled area.
6. Following this, wipe area dry with a clean, white, cotton cloth.
CLEANING LEATHER SEATS (IF EQUIPPED)
Note: Follow the same procedure as cleaning leather seats for cleaning
leather instrument panels and leather interior trim surfaces.
For routine cleaning, wipe the surface with a soft, damp cloth and a mild
soap and water solution. Dry the area with a clean, soft cloth.

For cleaning and removing spots and stains such as dye transfer, use
Motorcraft Premium Leather and Vinyl Cleaner or a commercially
available leather cleaning product for automotive interiors.
Note:Test any cleaner or stain remover on an inconspicuous area.
You should:
• Remove dust and loose dirt with a vacuum cleaner.
• Clean and treat spills and stains as soon as possible.
Do not use the following products as these may damage the leather:
• Oil and petroleum or silicone-based leather conditioners.
• Household cleaners.
• Alcohol solutions.
• Solvents or cleaners intended specifically for rubber, vinyl and
plastics.Motorcraft
Note: Do not use Motorcraft Premium Leather and Vinyl Cleaner ZC-56
on Lincoln Black Label, Presidential or Reserve Leathers because it can
damage these and other semi-aniline leather seating fabrics. It can also
damage surrounding microfiber accent surfaces. To clean Lincoln Black
Label, Presidential or Reserve Leather, first vacuum the seats to remove
loose dirt. Then wipe the leather with a clean soft cloth dampened with
lukewarm water and a mild soap. Wipe the leather again with a slightly
damp cloth to remove soap residue, and dry with a soft cloth. To
maintain the leather’s resiliency, it should be cleaned whenever soiled.
CLEANING THE ALLOY WHEELS
Note: Do not use chrome cleaner, metal cleaner or polish on wheels and
wheel covers.
A clearcoat paint finish coats aluminum wheels and wheel covers. In
order to maintain their condition:
• Clean weekly with Motorcraft Wheel and Tire Cleaner. Use a sponge to
remove heavy deposits of dirt and brake dust accumulation. Rinse
thoroughly with a strong stream of water when you have completed
the cleaning process.
• To remove tar and grease, use Motorcraft Bug and Tar Remover.
• Never apply any cleaning chemical to hot or warm wheel rims or
covers.
• Some automatic car washes may cause damage to the finish on your
wheel rims or covers.
Vehicle Care 291
2015 Navigator(nav)
Owners Guide gf, 2nd Printing, December 2014
USA (fus)

•Industrial-strength (heavy-duty) cleaners, or cleaning chemicals, in
combination with brush agitation to remove brake dust and dirt, could
wear away the clearcoat finish over time.
• Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
• If you intend on parking your vehicle for an extended period after
cleaning the wheels with a wheel cleaner, drive your vehicle for a few
minutes before doing so. This reduces the risk of increased corrosion
of the brake discs.
VEHICLE STORAGE
