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. Remove the filler cap.
2. Add engine oil that meets the Ford
specifications. See Capacities and
Specifications (page 353).
3. Replace the filler cap. Turn it until you feel a strong resistance. 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 478).
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. See
Adding Engine Coolant
in this chapter.
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.

MKZ (), enUSA MaintenanceE142732

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
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 that the
engine coolant has degraded, nor does it
require that you drain the engine coolant,
flush the system or replace the engine
coolant. Do not mix different colors or types of
coolant in your vehicle. 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. Use
prediluted engine coolant meeting the Ford
specification. See Capacities and
Specifications (page 353).
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 coolant 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. 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 Ford specification.
See Capacities
and Specifications (page 353).
3. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle.
286
MKZ (), enUSA Maintenance

4. 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. 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 outside 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: A high engine temperature
message will appear in the
information display.
The service engine soon indicator
will light.
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, your 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.
287
MKZ (), enUSA Maintenance

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 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.
See an authorized dealer as soon as
possible. AUTOMATIC TRANSMISSION
FLUID CHECK
6F35/HF35 transmission (If Equipped)
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.
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.
See
Scheduled Maintenance (page 478).
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.

recommended. Use gloves when moving the air filter
assembly. Components will be hot.
Note:
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is warmed up
(approximately 20 miles [30 kilometers]). 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 turned 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.
