ENGINE COOLANT CHECK
Engine Coolant and Inverter
System Controller Coolant
Your vehicle is equipped with two
separate cooling systems. One is for
cooling the engine and one is for
cooling the inverter system controller
that is specific to the hybrid operating
system. The two systems operate
similarly, with the inverter system
controller cooling system generally
operating at a lower temperature and
pressure.
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
444).
Note: Make sure that the level is
between the MIN and MAX marks on
the engine 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
prediluted coolant immediately. See
Adding Engine Coolant
in 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 Rotunda tool
300-ROB75240 available from your
dealer. Ford does 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 or antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.

Adding Coolant 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, you can be burned if you spill
coolant on hot engine parts. 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 the cap is loosened slightly. 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
cooling or heating systems. This
damage would not be covered under
your vehicle ’s warranty.
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.
Note: It is very important to use
prediluted coolant meeting the Ford
specification in order to avoid plugging
the small coolant passageways. Use
of concentrated coolant and water
may cause coolant passageway
plugging and void the warranty. See
Capacities and Specifications (page
330).

MKZ (CC9) Maintenance

•
Do not mix different colors or types
of coolant in your vehicle. Make
sure the correct coolant is used.
Mixing of coolants may harm your
cooling system. The use of an
improper coolant may harm the
engine, inverter system controller,
and cooling system components
and may void the warranty.
• In case of emergency, a large
amount of water without engine
coolant may be added to the
engine cooling system only in order
to reach a vehicle service location.
In this instance, the engine cooling
system must be drained,
chemically cleaned with
Motorcraft Premium Cooling
System Flush, and refilled with
prediluted engine coolant as soon
as possible. Water alone (without
engine coolant) can cause engine
damage from corrosion,
overheating, or freezing. DO NOT
use this method for the inverter
system controller cooling system.
The inverter system controller
cooling system operates close to
ambient temperature, and is
susceptible to freezing in any
subfreezing environment in the
absence of coolant. •
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.
Adding Engine Coolant
1. Unscrew the engine coolant reservoir cap slowly. Any pressure
will escape as you unscrew the
cap.
2. Use a funnel to add prediluted engine coolant to the engine
coolant reservoir. Make sure that
the level is between the MIN and
MAX marks on the engine coolant
reservoir. Use prediluted engine
coolant meeting the Ford
specification. See Capacities and
Specifications (page 330).
3. Close the engine coolant reservoir
cap.
Whenever you add coolant, check the
coolant level in the engine coolant
reservoir the next few times you drive
the vehicle. If necessary, add enough
prediluted engine coolant to bring the
engine coolant level to the proper
level.

Adding Inverter System
Controller Coolant
1. Open the inverter system
controller coolant reservoir cap.
2. Use a funnel to add prediluted coolant to the inverter system
controller coolant reservoir. Make
sure that the level is between the
MIN and MAX marks on the
inverter system controller coolant
reservoir. Use prediluted coolant
meeting the Ford specification.
See Capacities and
Specifications (page 330).
3. Close the inverter system controller coolant reservoir cap.
Whenever you add coolant, check the

necessary, add enough prediluted
coolant to bring the inverter system
controller 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 an
authorized Ford 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.
If you drive in extremely hot climates:
• It may be necessary to have an
authorized Ford 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 coolant meeting the Ford
specification 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 re-started. 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 the
vehicle in fail-safe mode only as long
as necessary to bring the vehicle to
rest in a safe location and seek
immediate repairs. When in fail-safe
mode, the 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. Note:
Driving the vehicle without
repairing the engine problem increases
the chance of engine damage. Take
your vehicle to an authorized dealer as
soon as possible.
285
MKZ (CC9) Maintenance

You have limited engine power when
in the fail-safe mode, so drive the
vehicle with caution. The vehicle will
not be able to maintain high-speed
operation and the engine will run
rough. Remember that the engine is
capable of completely shutting down
automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely
possible and turn off the engine.
2. Arrange for the vehicle to be taken
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 replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
AUTOMATIC
TRANSMISSION FLUID
CHECK
Note: Transmission fluid should be
checked by an authorized dealer. If
required, fluid should be added by an
authorized dealer.
The automatic transmission does not
have a transmission fluid dipstick. Have an authorized dealer check and
change the transmission fluid at the
correct service interval. See
Scheduled Maintenance (page 444).
Your transmission does not consume
fluid. However, the fluid level should
be checked if the transmission is not
working properly, (i.e., if the
transmission slips or shifts slowly) or
if you notice some sign of fluid
leakage.
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.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX
lines are within the normal operating
range; there is no need to add fluid. If
the fluid levels are outside of the
normal operating range, the
performance of the system could be
compromised; seek service from your
authorized dealer immediately.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an
electric power steering (EPS) system.
There is no fluid reservoir to check or
fill.
