SCHEDULED MAINTENANCE
The scheduled maintenance services in thescheduled maintenance
informationof this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft® parts are designed and
built for best performance in your vehicle.
ENGINE OIL
Checking the engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
3. Allow at least20 minutesafter engine shutdown to ensure that the oil
contained in the upper parts of the engine has returned to the oil pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it
clean and reinsert fully.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level within the
crosshatch area on the dipstick by
adding oil as required. Do not
overfill the oil past the maximum
line as depicted by the arrow.
Engine oil specifications
It is important that only quality engine oils are used in your diesel engine
and it is changed at the recommended service interval. For normal or
severe service, use Motorcraft® oil or an equivalent oil conforming to
Ford specifications or API service categories CJ-4 as listed in the
Capacities and Specificationschapter. It is important to use the
Maintenance

recommended oils because they will provide acceptable engine
performance and durability. These oils are also compatible with the
emission control equipment of your vehicle to meet the more stringent
emission standards.
The use of correct oil viscosities for diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval
from the following SAE viscosity grade chart.
1For severe duty usage, use SAE 5W-40 API CJ-4.
2For biodiesel (grades B6-B20) usage, use SAE 5W-40 or SAE
15W-40 API CJ-4.
An engine block heater is recommended at temperatures below –10°F
(–23°C).
The American Petroleum Institute
(API) service symbol is used to
identify the proper engine oil for
your engine. The API service symbol
will be included on the oil container
you purchase. The API displays the
oil performance category in the top
half of symbol and the viscosity
grade in the center of the symbol.

Changing the engine oil and oil filter
WARNING:Do not handle a hot oil filter with bare hands.
WARNING:Continuous contact with used motor oil has caused
cancer in laboratory mice. Protect your skin by washing with
soap and water.
Your vehicle is equipped with an Intelligent Oil Life Monitor™ that
calculates the proper oil change service interval. When the information
display indicates:OIL CHANGE REQUIRED, change the engine oil and
oil filter. See theInformation Displayschapter in theOwner Manual
for more information.
Refer toMotorcraft part numberstheCapacities and Specifications
chapter for the engine oil filter part number. This filter protects your
engine by filtering harmful, abrasive or sludge particles and particles
significantly smaller than most available “will-fit” filters.
To change the engine oil and oil filter:
1. Unscrew the oil filter and oil pan drain plug and wait for the oil to drain.
Note:The oil pan drain plug only requires 1/4 turn to removal/install. A
3/8 inch socket drive may be used to assist with removal/installation, but be
careful not to over-tighten the plug during installation.
2. Replace the filter.
3. Reinstall the oil pan drain plug.
4. Refill the engine with new oil. For the proper capacity, seeCapacities
and Specificationschapter.
5. Reset the Intelligent Oil Life Monitor™. See theInformation Displays
chapter in theOwner Manualfor more information.
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

ENGINE AND SECONDARY COOLING SYSTEM COOLANT
Checking the engine coolant
The concentration, additive strength and level of coolant should be
checked at the mileage intervals listed in thescheduled maintenance
information.Be sure to read and understandPrecautions when
servicing your vehiclein yourOwner’s Manual.
When the engine is cold, check the level of coolant in the reservoirs. See
Under Hood Overviewfor the location of the engine and secondary
cooling system reservoirs. If the coolant has not been checked at the
recommended interval, the engine or secondary coolant reservoir may
become low or empty. If either reservoir is low or empty, add coolant to
the reservoir(s). Refer toEngine and secondary cooling system refill
procedurein this chapter.
Note:The engine coolant should be between the MIN and MAX marks
(within the COLD FILL RANGE), as listed on the engine coolant reservoirs.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
If the level is below the MIN mark, add engine coolant immediately see
Adding coolantin this chapter.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300– ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30 °F and -34 °F.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.

Adding engine coolant
WARNING:Do not add coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
WARNING:Do not put coolant in the windshield washer fluid
container. If sprayed on the windshield, coolant could make it
difficult to see through the windshield.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system(s) are under pressure; steam and hot liquid can
come out forcefully when the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets, cooling system sealants or unapproved
additives as they can cause damage to the engine cooling and/or heating
systems. This damage would not be covered under your vehicle’s warranty.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. If the engine coolant is clear and
uncontaminated, this color change does not indicate the engine coolant
has degraded nor does it require the engine coolant to be drained, the
system to be flushed, or the engine coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle. Only
use prediluted engine coolant that meets Ford specification . Mixing of
engine coolants may harm your engine’s cooling system. The use of an
improper coolant may harm engine and cooling system components
and may void the warranty.
•In case of emergency, a large amount of water without engine coolant
may be added in order to reach a vehicle service location. In this
instance, the cooling system must be drained, chemically cleaned, and
refilled with engine coolant as soon as possible per the instructions in
the Workshop Manual. Water alone (without engine coolant) can cause
engine damage from corrosion, overheating or freezing.DO NOTuse
this method for the secondary cooling system. The secondary cooling
system operates close to ambient temperature, and is susceptible to
freezing in any subfreezing environment, in the absence of coolant.

•Do not use alcohol, methanol or brine or any engine coolants mixed
with alcohol or methanol antifreeze (coolant). Alcohol and other
liquids can cause engine damage from overheating or freezing.
•Do not add extra inhibitors or unapproved additives to the coolant.
These can be harmful and compromise the corrosion protection of the
engine coolant.
Add prediluted engine coolant meeting the Ford specification
(Motorcraft® Orange Antifreeze/Coolant Prediluted). SeeCapacities
and Specificationsfor more information. Note: Generic coolants for all
makes and models may not meet the Ford specification and may cause
damage to the cooling system. This damage may void the warranty.
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 engine coolant
(Motorcraft® Orange Antifreeze/Coolant Prediluted) to the FULL COLD
level. For all other 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 of a vehicle with an overflow system, follow
these steps to add engine coolant.
1. Turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise until pressure begins to release.
3. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
4. Fill the coolant reservoir slowly with prediluted engine coolant to
within the FULL COLD level, or between the MIN and MAX marks
(within the COLD FILL RANGE), as listed on the engine coolant
reservoir. If you removed the radiator cap in an overflow system, fill the
radiator until the coolant is visible and radiator is almost full. If coolant is
added to bring the level within the COLD FILL RANGE when the engine
is not cold, the system may remain under filled.
5. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough prediluted engine coolant to bring the coolant
level to the proper level.

If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low level
of coolant can result in engine overheating and possible engine damage.
Engine and secondary cooling system refill procedure
The following procedure should be used 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 while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Slowly add prediluted engine coolant to the coolant reservoir until the
coolant level is within the COLD FILL RANGE as listed on the reservoir.
6. Reinstall the pressure relief cap.
7. Start and run the engine at 2,000 rpm for 2 minutes.
8. Shut 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 COLD FILL RANGE as listed on the
reservoir.
10. Engine cooling system: Repeat Step 5 until the coolant level has
stabilized (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).
Secondary cooling system: Repeat Step 5 until the coolant level has
stabilized (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).
11. Reinstall the pressure relief cap. Shut the engine off and let it cool.
12. Check the coolant level in the reservoir before you drive your vehicle
the next few times (with the engine cool).
