2015 LINCOLN MKZ HYBRID engine overheat

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 346). •
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 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
346
).
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 346).
3. Close the inverter system controller coolant reservoir cap. Whenever you add coolant, check the
coolant level in the inverter system controller
coolant reservoir the next few times you
drive the vehicle. If 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 WARNINGS
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.
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.

Your vehicle is equipped with an information
display, which indicates the proper oil
change interval. This interval may be up to
one year or 10000 miles (16000 kilometers).
When ENGINE OIL CHANGE DUE or OIL
CHANGE REQUIRED appears in the
information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 miles (800
kilometers) of the
ENGINE OIL CHANGE
DUE or OIL CHANGE REQUIRED message
appearing. Make sure you reset the oil
monitoring system after each oil change.
See
Engine Oil Check (page 288).
If your information display resets
prematurely, becomes inoperative or the
vehicle battery becomes discharged or
disconnected, the oil monitoring system
resets to 100% oil life. You should change
your engine oil one year or 10000 miles
(16000 kilometers) from the previous oil
change. Never exceed one year or 10000
miles (16000 kilometers) between oil change
intervals. Your vehicle is very sophisticated and built
with multiple, complex, performance systems.
Every manufacturer develops these systems
using different specifications and
performance features. That is why it is
important to rely upon your dealership to
properly diagnose and repair your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts and
component systems based upon engineering
testing. Ford Motor Company relies upon this
testing to determine the most appropriate
mileage for replacement of oils and fluids to
protect your vehicle at the lowest overall cost
to you and recommends against
maintenance schedules that deviate from
the scheduled maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or Ford-authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and the Ford Workshop
Manual list the recommended additives and
chemicals for your vehicle. We do not
recommend using chemicals or additives not
approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal
operating characteristic and, by itself, does
not necessarily indicate a concern or that the
fluid needs to be changed. However, a
qualified expert, such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also show signs
of overheating or foreign material
contamination immediately.
