Ford F-650/750 (2018 year). Manual — part 47

Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.

E142732

Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Committee (ILSAC).

To top up the engine oil level do the
following:

1.

Clean the area surrounding the engine
oil filler cap before you remove it.

2. Remove the engine oil filler cap. See

Under Hood Overview (page 188).
Turn it counterclockwise and remove
it.

3. Add engine oil that meets Ford

specifications. See Capacities and
Specifications (page 261). You may
have to use a funnel to pour the engine
oil into the opening.

4. Recheck the oil level.

5. If the oil level is correct, replace the

dipstick and make sure it is fully seated.

6. Replace the engine oil filler cap. Turn

it clockwise until you feel a strong
resistance.

Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.

Note: Make sure you install the oil filler cap
correctly.

Note: Soak up any spillage with an
absorbent cloth immediately.

CHANGING THE ENGINE OIL
AND OIL FILTER

WARNINGS

Do not handle a hot oil filter with
bare hands.

Continuous contact with used motor
oil has caused cancer in laboratory
mice. Protect your skin by washing

with soap and water.

If your vehicle is equipped with a diesel
engine, an Intelligent Oil Life Monitor™
calculates the proper oil change service
interval. When the information display
indicates: OIL CHANGE REQUIRED, change
the engine oil and oil filter. See
Information Displays (page 64).

The engine oil filter protects your engine
by filtering harmful, abrasive or sludge
particles and particles significantly smaller
than most available will-fit filters. See
Motorcraft Parts (page 258).

1.

Unscrew the oil filter and oil pan drain
plug and wait for the oil to drain.

2. Replace the filter.

3. Reinstall the oil pan drain plug.

4. Refill the engine with new oil. See

Capacities and Specifications (page
269).

5. For diesel engines, you need to reset

the Intelligent Oil Life Monitor™. See
Information Displays (page 64).

Engine lubrication for severe
service operation

The following conditions define severe
operation for which engine operation with
SAE 5W-40 API CJ-4 is recommended. Oil
and oil filter change intervals will be
determined by the Intelligent Oil Life
Monitor™ as noted previously.

•

Frequent or extended idling (over 10
minutes per hour of normal driving).

•

Low-speed operation/stationary use.

•

If vehicle is operated in sustained
ambient temperatures below -9°F
(-23°C) or above 100°F (38°C).

•

Frequent low-speed operation,
consistent heavy traffic less than
25 mph (40 km/h).

•

Operating in severe dust conditions.

•

Operating the vehicle off road.

•

Towing a trailer over 1,000 mi
(1,600 km).

•

Sustained, high-speed driving at Gross
Vehicle Weight Rating (maximum
loaded weight for vehicle operation).

•

Use of fuels with sulfur content other
than ultra-low sulfur diesel (ULSD).

•

Use of high-sulfur diesel fuel.

CHANGING THE COALESCER
FILTER ELEMENT

(If Equipped)

WARNING

Do not dispose of engine oil or oil
filters in the household refuse or the
public sewage system. Use an

authorized waste disposal facility.

Do not clean or recondition the filter
element.

We recommend that you demand the use
of genuine Ford and Motorcraft® parts
whenever your vehicle requires scheduled
maintenance or repair. Use the correct
specification filter element. See
Motorcraft Parts (page 257).

Note: Operating your vehicle without a filter
element or with an unapproved filter
element may result in damage to the turbo
charger or exchanger and could lead to
engine damage that may not be covered by
the vehicle Warranty.

the steering wheel to reset the oil change
indicator. See General Information
(page 64).

ENGINE COOLANT CHECK -
6.7L DIESEL

WARNINGS

Never remove the coolant reservoir
cap when the engine is running or
hot.

WARNINGS

Do not put coolant in the windshield
washer reservoir. If sprayed on the
windshield, coolant could make it

difficult to see through the windshield.

To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure

relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly.

Do not add coolant further than the
MAX mark.

When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 320).

Note: Make sure that the coolant level is
between the MIN and MAX marks on the
coolant reservoir.

Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.

Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.

Adding Coolant

WARNINGS

Do not add engine coolant when the
engine is hot. Failure to follow this
instruction could result in personal

injury.

Never remove the coolant reservoir
cap when the engine is running or
hot.

Note: Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.

Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.

It is very important to use prediluted
coolant approved to the correct
specification in order to avoid plugging the
small passageways in the engine cooling
system. See Capacities and
Specifications (page 269). 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 Ford
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.

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. Unscrew the cap slowly. Any pressure

escapes as you unscrew the cap.

3. Fill the coolant reservoir slowly 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 coolant is added 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, 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 269).
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.

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.
