2020 FORD F-150 heating

Note:
Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See
Capacities and Specifications (page
424).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap. Turn
the cap clockwise until it contacts the
hard stop.
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.
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.
In case of emergency, you can add a large
amount of water without engine coolant
in order to reach a vehicle service location.
In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant as soon as possible. Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
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.
Note: Dispose of used coolant in the
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.

Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management (If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a 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 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 stop your vehicle. You can
continue to drive.
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. Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after
several minutes, 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.

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 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 363).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption this includes extended time
at high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. As a result, you
need to check the engine oil level at every
refueling and adjust to maintain proper
levels to avoid engine damage.
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.
We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.
We rely 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
our genuine or our authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and our 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 our 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.
