2014 LINCOLN MKZ HYBRID engine overheat

•
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 302).
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 302).
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.

General Information
WARNING
Failure to follow these guidelines
could result in an increased risk of
loss of vehicle control, injury or death. Note:
Do not use the kit if a tire has
become severely damaged by driving the
vehicle with a tire that has insufficient air
pressure. Only punctured areas located
within the tire tread can be sealed with
the kit.
Do not attempt to repair punctures larger
than 1/4 inch (6 millimeters) or damage to
the tire's sidewall. The tire may not
completely seal.
Loss of air pressure may adversely affect
tire performance. For this reason:
Note: Do not drive the vehicle above 50
mph (80 km/h).
Note: Do not drive further than 120 miles
(200 kilometers). Drive only to the closest
Ford Motor Company authorized dealer
or tire repair shop to have your tire
inspected.
• Drive carefully and avoid abrupt
steering maneuvers.
• Periodically monitor tire inflation
pressure in the affected tire; if the tire
is losing pressure, have the vehicle
towed.
• Read the information in the Tips for
Use of the Kit section to make sure
safe operation of the kit and your
vehicle. Tips for Use of the Kit
Read the following list of tips to ensure
safe operation of the kit:
•
Before operating the kit, make sure
your vehicle is safely off the road and
away from moving traffic. Turn on the
hazard lights.
• Always set the parking brake to ensure
the vehicle doesn't move
unexpectedly.
• Do not remove any foreign objects,
such as nails or screws, from the tire.
• When using the kit, leave the engine
running (only if the vehicle is outdoors
or in a well-ventilated area) so the
compressor doesn't drain the vehicle's
battery.
• Do not allow the compressor to
operate continuously for more than 15
minutes; this will help prevent the
compressor from overheating.
• Never leave the kit unattended when
it is operating.
• Sealant compound contains latex.
Make sure that you use the non-latex
gloves provided to avoid an allergic
reaction.
• Keep the kit away from children.
• Only use the kit when the ambient
temperature is between -22°F (–30°C)
and 158°F (70°C).
• Only use the sealing compound before
the use by date. The use by date is on
the lower right hand corner of the label
located on the sealant canister (bottle).
Check the use by date regularly and
replace the canister after four years.

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.
Make sure to change your vehicle
’s oils
and fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using a Ford-approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
