Lincoln MKS (2016 year). Manual - part 16

ENGINE COOLANT CHECK

WARNINGS

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, spilling
coolant on hot engine parts can burn you.

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.

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 you loosen the cap slightly.

Do not add coolant further than the
MAX mark.

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. See Scheduled
Maintenance (page 321).

Note: Make sure that the coolant 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.

Maintain coolant concentration 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

Note: Do not use stop leak pellets, cooling
system sealants or additives as they can cause
damage to the engine cooling or heating
systems. Your warranty may not cover these
damages.

Note: During normal vehicle operation, the
coolant may change color from orange to pink
or light red. As long as the coolant is clear and
uncontaminated, this color change does not
indicate the coolant has degraded nor does it
require the coolant to be drained, the system
to be flushed, or the coolant to be replaced.

Do not mix different colors or types of coolant
in your vehicle. Mixing of engine coolants may
harm your engine’s cooling system. Use
prediluted engine coolant meeting the correct
specification.  See Capacities and
Specifications (page 296).  The use of an
incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.

In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:

1.

Must drain the cooling system.

2. Chemically clean the cooling system with

Motorcraft Premium Cooling System
Flush.

3. Refill with engine coolant as soon as

possible.

Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.

247

MKS (CLE) Canada/United States of America, enUSA, First Printing

Maintenance

Do not use the following as a coolant
substitute:
•

Alcohol.

•

Methanol.

•

Brine.

•

Any engine coolant mixed with alcohol
or methanol antifreeze or 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.

When adding coolant:

1.

Unscrew the cap slowly. Any pressure will
escape as you unscrew the cap.

2. Add prediluted engine coolant meeting

the correct specification.  See Capacities
and Specifications (page 296).

3. Check the coolant level in the coolant

reservoir the next few times you drive your
vehicle.

4. If necessary, add enough prediluted

engine coolant to bring the coolant level
to the proper level.

Recycled Engine Coolant

We do not recommend the use of recycled
engine coolant as an 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 an authorized
dealer increase the coolant concentration
above 50%.

•

A coolant concentration of 60% provides
improved freeze point protection. Engine
coolant concentrations above 60%
decrease the overheat protection
characteristics of the engine coolant and
may cause engine damage.

If you drive in extremely hot climates:
•

It may be necessary to have an authorized
dealer decrease the coolant
concentration to 40%.

•

A coolant concentration of 40% provides
improved overheat protection. Engine
coolant concentrations below 40%
decrease the freeze and corrosion
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 you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. 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:

248

MKS (CLE) Canada/United States of America, enUSA, First Printing

Maintenance

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
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.

When this occurs, your vehicle will still
operate. However:
•

The engine power will be limited.

•

This will disable the air conditioning
system.

Continued operation increases the engine
temperature, causing the engine to
completely shut down.  Your steering and
braking effort increases in this situation.

When the engine temperature cools, you can
re-start your engine. Take your vehicle to an
authorized dealer as soon as possible to
minimize engine damage.

When Fail-Safe Mode Is Activated

WARNINGS

Fail-safe mode is for use during
emergencies only. Operate your vehicle
in fail-safe mode only as long as

necessary to bring your vehicle to rest in a
safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will have
limited power, will not be able to maintain
high-speed operation, and may completely
shut down without warning, potentially losing
engine power, power steering assist, and
power brake assist, which may increase the
possibility of a crash resulting in serious injury.

Never remove the coolant reservoir cap
while the engine is running or hot.

You have limited engine power when in the
fail-safe mode, so drive your vehicle with
caution. Your vehicle will not maintain
high-speed operation and the engine will
operate poorly.

Remember that the engine is capable of
automatically shutting down to prevent
engine damage.  In this situation:

1.

Pull off the road as soon as safely
possible and switch off the engine.

2. Tow your vehicle to an authorized dealer.

3. If this is not possible, wait a short period

for the engine to cool.

4. Check the coolant level and add if low.

5. Re-start the engine and drive your vehicle

to an authorized dealer.

Note: Driving your vehicle without repair
increases the chance of engine damage.
Contact an authorized dealer as soon as
possible.

Engine Fluid Temperature Management
(If Equipped)

WARNINGS

To reduce the risk of crash and injury,
be prepared that the vehicle speed may
reduce and the vehicle may not be able

to accelerate with full power until the fluid
temperatures reduce.

Never remove the coolant reservoir cap
while the engine is running or hot.

Your vehicle can pull a trailer, but because
of the added load, your vehicle’s engine may
temporarily reach higher temperatures during
severe operating conditions such as
ascending a long or steep grade while pulling
a trailer in high temperatures.

249

MKS (CLE) Canada/United States of America, enUSA, First Printing

Maintenance

At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear in
the information display.

You may notice a reduction in vehicle speed
caused by reduced engine power. In order to
manage the engine fluid temperatures, your
vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on many factors such as vehicle
loading, towing, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to drive
your vehicle while this message is active.

The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When the
engine coolant temperature decreases to a
normal operating temperature, the air
conditioning will turn on once again.

If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:

1.

Pull off the road as soon as safely
possible and shift the transmission into
P.

2. Leave the engine running until the coolant

temperature gauge needle moves away
from the red (hot) area. After several
minutes, if the temperature does not
drop, follow the remaining steps.

3. Switch the engine off and wait for it to

cool before checking the coolant level.

4. If the coolant level is normal, restart your

engine and continue.

5. If the coolant is low, add coolant, and

restart the engine. See Adding Engine
Coolant or How Fail-Safe Cooling
Works in this chapter for more
information.

BRAKE FLUID CHECK

WARNINGS

Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of

incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other

materials may result in brake system damage
or failure. Failure to adhere to this warning
could result in the loss of vehicle control,
serious personal injury or death.

Do not allow the fluid to touch your skin
or eyes. If this happens, rinse the
affected areas immediately with plenty

of water and contact your physician.

A fluid level between the MAX and
MIN lines is within the normal
operating range and there is no need

to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your vehicle
checked immediately.

E170684

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.

Only use fluid that meets Ford specifications.
See Capacities and Specifications (page
296).

POWER STEERING FLUID CHECK

Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.

WASHER FLUID CHECK

WARNING

If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze protection.

Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase the
risk of injury or accident.

Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets Ford
specifications.  See Capacities and
Specifications (page 296).

State or local regulations on volatile organic
compounds may restrict the use of methanol,
a common windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be
used only if they provide cold weather
protection without damaging the vehicle’s
paint finish, wiper blades or washer system.

Maintenance

FUEL FILTER

Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.

CHANGING THE 12V BATTERY

WARNINGS

Batteries normally produce explosive
gases which can cause personal injury.
Therefore, do not allow flames, sparks

or lighted substances to come near the
battery. When working near the battery,
always shield your face and protect your
eyes. Always provide correct ventilation.

When lifting a plastic-cased battery,
excessive pressure on the end walls
could cause acid to flow through the

vent caps, resulting in personal injury and
damage to the vehicle or battery. Lift the
battery with a battery carrier or with your
hands on opposite corners.

WARNINGS

Keep batteries out of reach of children.
Batteries contain sulfuric acid. Avoid
contact with skin, eyes or clothing.

Shield your eyes when working near the
battery to protect against possible splashing
of acid solution. In case of acid contact with
skin or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call
a physician immediately.

Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after

handling.

This vehicle may be fitted with more
than one battery. Removing the battery
cables from only one battery does not

disconnect your vehicle electrical system.
Make sure you disconnect the battery cables
from all batteries when disconnecting power.
Failure to do so may cause serious personal
injury or property damage.

Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.

When a battery replacement is required, you
must use a recommended replacement
battery that matches the electrical
requirements of the vehicle.

Note: After cleaning or replacing the battery,
make sure you reinstall the battery cover or
shield.

Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in the
vehicle.

For longer, trouble-free operation, keep the
top of the battery clean and dry.

If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.

255

MKS (CLE) Canada/United States of America, enUSA, First Printing

Maintenance

Because your vehicle’s engine is electronically
controlled by a computer, some control
conditions are maintained by power from the
battery. When the battery is disconnected or
a new battery is installed, the engine must
relearn its idle and fuel trim strategy for
optimum driveability and performance.
Flexible fuel vehicles (FFV) must also relearn
the ethanol content of the fuel for optimum
driveability and performance.

To restore the settings, do the following:

1.

Apply the parking brake.

2. Shift into park (P) or neutral (N).

3. Switch off all accessories.

4. Press the brake pedal and start your

vehicle.

5. Run the engine until it reaches normal

operating temperature. While the engine
is warming up, complete the following:
Reset the clock.  See Audio System
(page 313).  Reset the power windows
bounce-back feature.  See Windows and
Mirrors (page 78).  Reset the radio
station presets.  See Audio System
(page 313).

6. Allow the engine to idle for at least one

minute.

7.

Drive the vehicle at least 10 mi (16 km) to
completely relearn the idle trim and fuel
trim strategy.

Note: If you do not allow the engine to relearn
the idle and fuel trim strategy, the idle quality
of your vehicle may be adversely affected until
the engine computer eventually relearns the
idle trim and fuel trim strategy.

Note: For flexible fuel vehicles, if you are
operating on E85, you may experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned.

Make sure that you dispose of old batteries
in an environmentally friendly way.  Seek
advice from your local authority about
recycling old batteries.

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.

Battery Management System

 (If

Equipped)

The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery drain
is detected, the system temporarily disables
some electrical systems to protect the
battery.

Systems included are:
•

Heated rear window.

•

Heated seats.

•

Climate control.

•

Heated steering wheel.

•

Audio unit.

•

Navigation system.

A message may appear in the information
displays to alert you that battery protection
actions are active. These messages are only
for notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.

256

MKS (CLE) Canada/United States of America, enUSA, First Printing

Maintenance

After battery replacement, or in some cases
after charging the battery with an external
charger, the battery management system
requires eight hours of vehicle sleep time to
relearn the battery state of charge. During
this time your vehicle must remain fully
locked with the ignition switched off.

Note: Prior to relearning the battery state of
charge, the battery management system may
temporarily disable some electrical systems.

Electrical Accessory Installation

To make sure the battery management
system works correctly, do not connect an
electrical device ground connection directly
to the battery negative post. This can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.

Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability. This
may also affect the performance of other
electrical systems in the vehicle.

CHANGING THE ENGINE AIR
FILTER

WARNING

Do not start the engine with the air
cleaner removed. This can cause
damage not covered by the vehicle

Warranty and can result in serious injury.

When changing the air filter element, use only
the air filter element listed.  See Capacities
and Specifications (page 296).

For vehicles with EcoBoost engines, when
servicing the air cleaner, it is important that
no foreign material enters the air induction
system. The engine and turbocharger are
susceptible to damage from even small
particles.

Change the air filter element at the correct
interval.  See Scheduled Maintenance
(page 321).

Note:  Failure to use the correct air filter
element may result in severe engine damage.
Resulting component damage may not be
covered by the vehicle Warranty.

To replace the air filter element do the
following:

1.

Switch the ignition off.

2. Remove the clips that secure the air filter

housing cover.

3. Carefully lift the air filter housing cover.

4. Remove the air filter element from the air

filter housing.

5. Wipe any dirt or debris from the air filter

housing and cover to make sure no dirt
gets in the engine and that you have a
good seal.

6. Install a new air filter element.

7.

Install the air filter housing cover.  Be
careful not to crimp the filter element
edges between the air filter housing and
cover.  This could cause filter damage
and allow unfiltered air to enter the
engine if it is not properly seated.

8. Engage the clips to secure the air filter

housing cover to the air filter housing.
