overheating LINCOLN MKS 2016 User Guide

At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear in
the information display.
You may notice a reduction in vehicle speed
caused by reduced engine power. In order to
manage the engine fluid temperatures, your
vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on many factors such as vehicle
loading, towing, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to drive
your vehicle while this message is active.
The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When the
engine coolant temperature decreases to a
normal operating temperature, the air
conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Pull off the road as soon as safely possible and shift the transmission into
P
. 2.
Leave the engine running until the coolant
temperature gauge needle moves away
from the red (hot) area. After several
minutes, if the temperature does not
drop, follow the remaining steps.
3. Switch the engine off and wait for it to cool before checking the coolant level.
4. If the coolant level is normal, restart your
engine and continue.
5. If the coolant is low, add coolant, and restart the engine. See
Adding Engine
Coolant or How Fail-Safe Cooling
Works in this chapter for more
information.
AUTOMATIC TRANSMISSION
FLUID CHECK
6F50/6F55 Transmission
(If Equipped) WARNINGS
The dipstick cap and surrounding
components may be hot, use gloves.
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 your vehicle until you warm it up,
approximately
20 mi (30 km). If you operate
your vehicle for an extended period at high
speeds, in city traffic during hot weather or
pulling a trailer, switch your vehicle off until it
reaches normal operating temperatures 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, you should
check the fluid level if the transmission is not
working properly. For example, if the
transmission slips or shifts slowly or if you
notice some sign of a fluid leak.
1. Drive your vehicle 20 mi (30 km) or until it reaches normal operating temperature.
2. Park your vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your
foot on the brake pedal, start the engine
and move the gearshift lever through all
of the gear ranges. Allow a minimum of
10 seconds for each gear to engage.
4. Put the gearshift lever in park (P) and leave the engine running.

High fluid level
If the fluid level is above the MAX range of
the dipstick, remove fluid to reach the
hashmark level.
Note:
Fluid level above the MAX level may
cause shift or engagement concerns or
possible damage. An overheating condition
can cause high fluid levels. If you operate your
vehicle for an extended period at high speeds,
in city traffic during hot weather or pulling a
trailer, you should switch your vehicle off until
your vehicle reaches normal operating
temperatures. Depending on vehicle use,
cooling times could take up to 30 minutes or
longer. Adjusting Automatic Transmission Fluid
Levels
Before adding any fluid, make sure the correct
type is used. The type of fluid used is
normally indicated on the dipstick and in the
Technical Specifications section in this
chapter.
Note:
An overfill condition of transmission
fluid may cause shift or engagement concerns
or possible damage. 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.
Reinstall the air filter assembly. After you
check the fluid level and adjust as necessary,
do the following:
1. Switch the engine off.
2. Loosen the clamp holding the air filter
assembly to the rubber hose.
3. Seat the air filter assembly back into the grommets by pushing down on the air
filter assembly.
4. Tighten the clamp.
5. Install and tighten the two bolts that attach the air filter assembly to the front
of the vehicle.
6. Install the bolt cover.
7. Reinstall the harness retaining clip into the front of the air filter assembly.

When the oil change message 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 message appearing. Make
sure you reset the Intelligent Oil-Life Monitor
after each oil change. See (page 89).
If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or 5000
miles (8000 kilometers) from your last 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.
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.
