2019 FORD F-250 coolant reservoir

It is very important to use prediluted
coolant approved to the correct
specification to avoid plugging the small
passageways in the engine cooling system.
See Capacities and Specifications
(page 431). Do not mix different colors or
types of coolant in your vehicle. Mixing of
engine coolants or using an incorrect
coolant may harm the engine or cooling
system components and may not be
covered by the vehicle Warranty.
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, immediately add
prediluted coolant.
For vehicles with overflow coolant systems
with a non-pressurized cap on the coolant
recovery system, add coolant to the
coolant recovery reservoir when the engine
is cool. Add prediluted coolant to the
maximum level. For all vehicles which have
a coolant degas system with a pressurized
cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator,
follow these steps to add engine coolant:
1. Turn the engine off and let it cool.
2. Slowly unscrew the cap. Any pressure escapes as you unscrew the cap.
3. Slowly fill the coolant reservoir with prediluted engine coolant to within the
minimum and maximum range on the
engine coolant reservoir. If you
removed the radiator cap in an
overflow system, fill the radiator until
the coolant is visible and the radiator
is almost full. If you add coolant to
bring the level within the minimum and
maximum range when the engine is not
cold, the system may remain under
filled. 4. Replace the coolant reservoir cap and
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 proper 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 431).
Using water that has not been deionized
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.
In case of emergency, you can add a large
amount of water without prediluted
coolant in order to reach a vehicle service
location. On arrival do the following:
1. Drain the cooling system.
2. Chemically clean the cooling system. We recommend Motorcraft Premium
Cooling System Flush.
3. Refill with prediluted coolant as soon as possible.
Water alone, without prediluted 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 non-specified
additives to the coolant. These can be
harmful and compromise the corrosion
protection of the coolant.
Engine and Secondary Cooling
System Refill Procedure
Perform this procedure when refilling the
engine or secondary cooling systems after
it has been drained or become extremely
low:
1. Before you remove the cap, turn the
engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap
counterclockwise until pressure begins
to release.
3. Step back when the pressure releases.
4. When you are sure that all the pressure
has been released, use the cloth to turn
the cap counterclockwise and then
remove it.
5. Slowly add prediluted engine coolant to the coolant reservoir until the
coolant level is within the minimum
and maximum range as listed on the
reservoir.
6. Reinstall the pressure relief cap.
7. Start and run the engine at 2000 rpm for 2 minutes.
8. Shut the engine off, and remove the pressure relief cap as previously
outlined.
9. If required, add prediluted engine coolant to the coolant reservoir until
the coolant level is within the minimum
and maximum range as listed on the
reservoir. 10.
Engine cooling system: Repeat steps
5 through 9 until the coolant level has
stabilized and is no longer dropping
after each step and the upper
radiator hose at the radiator is warm
to the touch, indicating that the
engine thermostat is open and
coolant is flowing through the
radiator.
11. Check the secondary cooling system.
Repeat steps 1 through 10 until the
coolant level has stabilized and is no
longer dropping after each step and
the lower passenger side of the
secondary radiator is warm to the
touch, indicating secondary
thermostat is open and coolant is
flowing through the entire system.
12. Check the coolant level in both systems before you drive your vehicle
the next few times.
13. If necessary, add prediluted engine coolant to the coolant reservoirs until
the coolant level is within the
minimum and maximum range as
listed on the reservoir. After you add
coolant, check the coolant
concentration.
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.
