2017 LINCOLN MKZ HYBRID engine overheat

3.
Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.
Note: If prediluted coolant is not available,
use the approved antifreeze concentrate
diluting it to 50/50 with distilled water. See
Capacities and Specifications (page 354).
Using water that has not been deionised
may contribute to deposit formation,
corrosion or plugging of the small cooling
system passageways.
If you have to add more than
1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage. 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: In case of emergency, you can add a
large amount of water without coolant in
order to reach a vehicle service location.
Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing. When you reach a service
location, you must have the cooling system
drained, flushed and refilled using the
correct specification prediluted coolant or
antifreeze concentrate. See Capacities and
Specifications
(page 354).
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze. 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
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Dispose of used engine coolant 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 increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection. Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
354).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolant
temperature gauge moves toward the red
zone: A warning lamp illuminates and a
message may appear in the
information display.If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

You may notice a reduction in vehicle speed
caused by reduced engine power. In order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to pull off the road. You can
continue to drive your vehicle.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature does
not drop, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
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
479
). 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 WARNINGS
Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of incorrect fluid
could result in the loss of vehicle control,
serious personal injury or death.

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 mi
(200 km). Drive only to the closest authorized
Ford 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
To ensure safe operation of the kit:
• Read all instructions and cautions fully.
• 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 does not 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 during
operation.
• Sealant compound contains latex. Those
with latex sensitivities should use
appropriate precautions 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 a
label on the sealant canister and can be
seen through the rectangular viewing
window on the bottom of the compressor.
Check the use-by date regularly and
replace the canister after four years of
non-use.
• Do not store the kit unsecured inside the
passenger compartment of the vehicle
as it may cause injury during a sudden
stop or crash. Always store the kit in its
original location.
• After sealant use, the tire pressure
monitoring system sensor and valve stem
on the wheel must be replaced by an
authorized Ford dealer.
• Operating the kit could cause an
electrical disturbance in radio, CD, and
DVD player operation. * When inflation only is required for
a tire or other objects, the selector
must be in the Air position.

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 299).
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.
