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.

•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).

13. If necessary, add prediluted engine coolant to the coolant reservoir
until the coolant level is within the COLD FILL RANGE as listed on the
reservoir. After any coolant has been added, check the coolant
concentration. SeeEngine and secondary cooling system coolant
earlier in the chapter for more information.
Whenever coolant has been added, the coolant level in the reservoir
should be checked the next few times you drive the vehicle. If needed,
add prediluted engine coolant to bring the coolant to the proper level.
Recycled engine coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Always dispose of used automotive fluids in a responsible manner. Follow
your community’s regulations and standards for recycling and disposing
of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
to theCapacities and Specificationschapter.
Severe climates
If you drive in extremely cold climates:
•It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
•A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant concentrations above 60% will decrease the
overheat protection characteristics of the engine coolant and may
cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.

Checking coolant corrosion inhibitor additive strength
At specific mileage intervals of 15,000 miles (24,000 km), as listed in the
scheduled maintenance informationchapter, the coolant corrosion
inhibitor additive should be checked. The optional information display, if
equipped, will also display the messageCHECK COOLANT ADDITIVE
at this time. The purpose of checking is to verify the correct engine
coolant concentration (freeze point protection) and corrosion inhibitor
additive level (strength) of the coolant for maximum engine performance
and protection. Three products are available for ensuring the life and
health of the coolant: one tool, a test kit and a coolant inhibitor additive:
•Rotunda tool 300–ROB75240 available from your dealer –
recommended refractometer to test coolant concentration.
•
Rotunda 328-R071–ELC (Antifreeze Coolant ELC Contamination Kit) –
Evaluates the corrosion inhibitor additive strength. Note the first step is
to verify the vehicle’s coolant concentration is in the correct range of 40
– 60%. Coolant concentrations outside this range will not provide valid
test results. If the report results in a pass (i.e., the cooling system does
not show excessive contamination/the corrosion inhibitor additive
strength is sufficient), no action is required. If the report results as
insufficient (does not pass), the corrosion inhibitor additive strength of
the coolant is too low. If the ENGINE COOLING SYSTEM corrosion
inhibitor additive strength is low, add 48 fluid oz. of Motorcraft®
Specialty Orange Engine Coolant Revitalizer. If the SECONDARY
COOLING SYSTEM corrosion inhibitor additive strength is low, add 16
fluid oz. of Motorcraft® Specialty Orange Engine Coolant Revitalizer.
•Motorcraft® Specialty Orange Engine Coolant Revitalizer – Additive to
boost the corrosion inhibitor level based upon the test results of the
Antifreeze Coolant ELC Contamination Kit. The Revitalizer may be
added two times over the life of the coolant. If additional dosages are
required, the cooling system must be flushed and refilled per the
instructions in the Workshop Manual.
Refer to theCapacities and Specificationschapter for the proper
coolant and additive specifications.
Coolant change
At specific mileage intervals, as listed in thescheduled maintenance
information,the coolant should be changed. The optional information
display, if equipped, will also display the messageCOOLANT CHANGE

Engine-driven cooling fan (fan clutch)
Your vehicle is equipped with an engine driven cooling fan drive (also
called a fan clutch). This fan drive changes the fan speed to match the
vehicle’s changing cooling air flow requirements. Fan speed, fan noise
level and fuel consumption all will increase based on the driving
conditions that include trailer towing, hill climbing, heavy loads, high
speed and high ambient temperature, individually or in combination.
The fan drive is designed to provide the minimum fan speed (and
resulting minimum fan noise and fuel consumption) required to meet the
ever changing vehicle cooling air flow requirements. You will hear the
amount of fan noise increasing and decreasing as the engine power
requirements and vehicle driving conditions change as you drive. This is
to be expected as being normal to the operation of your vehicle. High
levels of fan noise might also be heard when your engine is first started,
and should normally decrease after driving for a short time.
AIR FILTER RESTRICTION GAUGE AND AIR FILTER REPLACEMENT
WARNING:To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air filter
removed and do not remove it while the engine is running.
Note:Vehicle operation in heavy snowfall or extreme rain conditions
may feed excessive amounts of snow/water into the air intake system.
This could plug/soak the air filter with snow and may cause the engine to
lose power and possibly shut down.
Air filter restriction gauge:
The restriction gauge, located on
the upper housing of the air filter
assembly, measures the vacuum
inside the air filter. The more the air
filter is restricted (dirty, clogged),
the higher the vacuum reading
Check the air filter restriction gauge
whenever the hood is raised to
perform general engine maintenance
at least every 7,500 miles (12,000 km). If the vehicle is operated in
extremely dusty conditions, check and reset the gauge at least every
500 miles (800 km), or two weeks, whichever comes first.

MINOR TROUBLESHOOTING GUIDE
Air purge procedure
Turn the key on for 30 seconds, then turn off. Repeat the procedure six
times.
If the engine won’t crank
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds.Wash hands after handling.
Turn on the headlights. If the lights are dim, do not go on at all or when
the ignition is turned to START the lights become dim or go out, the
battery connections may be loose or corroded, or the battery may be
discharged. If there is a clicking or stuttering sound coming from the
engine compartment when you turn the key to START, this may also
indicate a loose or corroded battery connection.
Check the battery connections at the battery posts, cable connection to
the engine grounding point and at the starter connection.
If a discharged battery is suspected, have it checked and corrected.
•The gearshift lever must be in P (Park) or N (Neutral) in order for
the starter to operate.
•Try operating the starter switch several times. Should the switch be
corroded, this operation may clean the contacts or make the switch
temporarily operable until you can reach the dealer.
•If all electrical connections are tight and you need assistance to start,
refer toJump startingin theRoadside Emergencieschapter of your
Owner’s Manual.
If engine cranks but won’t start
Prolonged starter cranking (in excess of 10 seconds) could cause
damage to the starter motor.
•
Check the fuel gauge. You may be out of fuel. If the gauge shows that
there is fuel in the tank, the trouble may be in the electrical system or
the fuel system. If equipped with an auxiliary tank, be sure that the tank
control switch is set for the tank with fuel and not on an empty tank.
•Leaving the ignition key turned to on for over two minutes without
starting may make starting difficult because the glow plugs will cease
activation. Reset the system by turning the ignition key to off and
then back to on again.

If fuses burn out
WARNING:Replacement fuses and circuit breakers must always
be the same rating as the original equipment shown. Never
replace a fuse or circuit breaker with one of a higher rating. Higher
rated fuses or circuit breakers could allow circuit overloading in the
event of a circuit malfunction, resulting in severe vehicle damage or
personal injury due to fire.
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
Refer to theOwner’s Manualfor replacement of fuses.
Selective catalytic reduction (SCR) system speed limit and
Idle-only modes
If the vehicle’s speed is limited or in an idle-only mode, the SCR system
may be limiting the vehicle’s functions due to low or contaminated diesel
