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.

Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant
WARNING: Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING: Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING: To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING: Do not add coolant further than the MAX mark.
Note: Do not use stop leak pellets, cooling system sealants or additives
as they can cause damage to the engine cooling or heating systems. This
damage would not be covered under your vehicle’s warranty.
Note: During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
• DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of engine coolants may harm
your engine’s cooling system. The use of an improper coolant may
harm engine and cooling system components and may void the
warranty.

•In case of emergency, a large amount of water without engine coolant
may be added in order to reach a vehicle service location. In this
instance, the cooling system must be drained, chemically cleaned with
Motorcraft Premium Cooling System Flush, and refilled with engine
coolant as soon as possible. Water alone (without engine coolant) can
cause engine damage from corrosion, overheating or freezing.
• Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause engine damage from overheating or freezing.
• Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the engine
coolant.
Unscrew the cap slowly. Any pressure will escape as you unscrew the
cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specifications for more information.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
• A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant concentrations above 60% will decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
Maintenance 269
2015 Navigator(nav)
Owners Guide gf, 2nd Printing, December 2014
USA (fus)

If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The fail-safe distance depends on ambient temperatures, vehicle load and
terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and: The coolant temperature warning light will illuminate.
The service engine soon indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
• The engine power will be limited.
• The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
