engine overheat LINCOLN MKZ 2013 User Guide

•
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.
Unscrew the cap slowly. Any pressure
will escape as you unscrew the cap.
Add prediluted engine coolant
meeting the Ford specification. See
Capacities and Specifications
(page 325).
Whenever coolant has been added,
the coolant level in the coolant
reservoir should be checked the next
few times you drive the vehicle. 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.
Always dispose of used automotive
fluids in a responsible 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 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. 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.

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 (6.4 mm) 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 km). 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 ensure
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).

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.
