2020 LINCOLN MKZ cooling

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
Avoid driving too fast during the first 1,000 mi
(1,600 km)
. Vary your speed frequently and
change up through the gears early. Do not
labor the engine.
Do not tow during the first
1,000 mi
(1,600 km).
REDUCED ENGINE PERFORMANCE WARNING:
If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle. If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Gauges (page
102).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 308).
5. Have your vehicle checked as soon as possible. ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.

WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, 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 you loosen the
cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 475).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
It is very important to use prediluted coolant
meeting the correct specification in order to
avoid plugging the small passageways in the
engine cooling system. See Capacities and
Specifications
(page 372). Incorrect
prediluted coolant use can cause damage
not covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 365).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.

MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Maintenance

Note:
Coolants marketed for all makes and
models may not be approved to Ford
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant meeting the correct specification. See Capacities and
Specifications (page 365).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
Do not mix different colors or types of
prediluted coolant in your vehicle. Mixing of
prediluted coolant or using an incorrect
prediluted 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.
3. Refill with prediluted coolant as soon as possible.
Water alone, without prediluted coolant, can
cause engine damage from corrosion,
overheating or freezing. Do not use the following as a coolant
substitute:
•
Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
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
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Dispose of used engine coolant 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 increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection. Coolant
concentrations below 40% decrease the
freeze and corrosion protection
characteristics of the coolant and may
cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
365).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolant
temperature gauge moves toward the red
zone: A warning lamp illuminates and a
message may appear in the
information display.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 still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
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 the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Maintenance

When Fail-Safe Mode Is Activated
WARNING: 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. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine may
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 the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.
3. If this is not possible, wait a short period
for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage. Engine Coolant Temperature
Management
(If Equipped) WARNING:
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 coolant temperature
reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

Note:
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle approximately 20 mi
(30 km) until it is warmed up. If your vehicle
has been operated for an extended period
at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle
should be switched off until normal operating
temperatures are reached to allow the fluid
to cool before checking. Depending on
vehicle use, cooling times could take up to
30 minutes or longer.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, the fluid level
should be checked if the transmission is not
working properly. For example, if the
transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
1. Drive the vehicle
20 mi (30 km) or until it
reaches normal operating temperature
2. Park the vehicle on a level surface and engage the parking brake. 3.
With the parking brake engaged and your
foot on the brake pedal, start the engine
and move the gearshift lever through all
of the gear ranges. Allow a minimum of
10 seconds for each gear to engage.
4. Put the gearshift lever in park (P) and leave the engine running.
Note: You will need to move the air filter
assembly to access the transmission
dipstick.
5. Remove the dipstick, wiping it clean with
a clean, dry lint free rag. If necessary,
refer to Under hood overview in this
chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube by turning it to
the locked position.
7. Remove the dipstick and inspect the fluid
level. The fluid should be in the
designated areas for normal operating
temperature. Moving the Air Filter Assembly (Accessing
the Dipstick) WARNING:
Do not start the engine
with the air filter removed. This can cause
damage not covered by the vehicle
Warranty and can result in serious injury. 1. Shut the engine off.
2. Clean the area around the clamps that
connect the air filter assembly to the
rubber hoses (A).

High fluid level
If the fluid level is above the MAX range of
the dipstick, remove fluid to reach the
hashmark level.
Note:
Fluid level above the MAX level may
cause shift or engagement concerns or
possible damage. High fluid levels can be
caused by an overheating condition. If your
vehicle has been operated for an extended
period at high speeds, in city traffic during
hot weather or pulling a trailer, the vehicle
should be switched off until normal operating
temperatures are reached. Depending on
vehicle use, cooling times could take up to
30 minutes or longer. Adjusting Automatic Transmission Fluid
Levels
Before adding any fluid, make sure the
correct type is used. The type of fluid used
is normally indicated on the dipstick and also
in the Technical Specifications section in this
chapter.Note:
An overfill condition of transmission
fluid may cause shift or engagement
concerns or possible damage.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
Reinstall the air filter assembly. After the fluid
level has been checked and adjusted as
necessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees
clockwise without disconnecting the
sensor.
4. Seat the air filter assembly back into the
grommets by pushing down on the air
filter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attach air filter assembly to the front of the
vehicle.
7. Install the bolt cover (if equipped).
