Adding and replacing engine coolant-7.3L Power Stroke and
Cummins B engines
Refer to the Scheduled Maintenance Guide for service intervals of the
engine cooling system.
Use Ford Premium Engine Coolant E2FZ-19549–AA (in Canada,
Motorcraft CXC-8–B) or a premium engine coolant that meets Ford
specification ESE-M97B44–A. Do not use alcohol or methanol antifreeze.
The use of an improper coolant may cause cooling system and/or engine
damage and may void the warranty of your vehicle’s engine cooling
system.
A mixture of 50% engine coolant concentrate and 50% water (50/50
ratio) is recommended to maintain best overall cooling system
performance. A 60/40 antifreeze to water ratio is acceptable for
extremely cold climates, but the coolant and water mixture must be
returned to a 50/50 ratio at the end of the winter season. To avoid
damaging the cooling system and engine, the coolant and water mixture
should never exceed a 60/40 antifreeze to water ratio.
Operating the engine with insufficient coolant can cause severe
cooling system and engine damage.
When refilling the engine cooling system as part of regular maintenance
or due to service, adhere to the following instructions:
1. Drain and flush the cooling system to remove dirt deposits, oil and
rust particles. Always dispose of used automotive fluids following your
community’s standards.
2. Fill the coolant reservoir with the specified coolant and water mixture
until the level stabilizes within the cold fill range.
3. Reinstall the coolant reservoir cap.
4. Start and idle the engine until the upper radiator hose is warm
(approximately 10–15 minutes). If the hose does not get warm, repeat
this step at a higher engine speed.
5. Once the hose is warm, shut the engine off.
6. Cautiously remove the coolant reservoir cap as previously described,
and add the specified coolant and water mixture until the level stabilizes
within the cold fill range of the coolant reservoir.
7. Reinstall the engine coolant reservoir cap.

FAN CLUTCHES
Your vehicle’s cooling system is equipped with a viscous variable speed
fan clutch.
•The fan clutch helps control cooling, increase performance, improve
fuel economy and reduce noise.
•The fan clutch is controlled by bimetallic spring sensors. Do not
tamper with these sensors as this may change their calibration or keep
the fan clutch from operating at all.
Stay clear of the fan/fan area while the engine is running or
possible personal injury may occur.
CHECKING AND ADDING POWER STEERING FLUID
Checking power steering fluid level
Check the power steering fluid level using the following procedure. Refer
to the Scheduled Maintenance Guide for the recommended service
intervals. If adding fluid is necessary, use only MERCONAT F.
1. Set the parking brake, shift into N
(Neutral) (automatic transmission)
or 1 (First) (manual transmission)
and turn the engine off.
2. Open the hood.
3. Clean the top of the power
steering fluid reservoir.
4. Remove the dipstick from the
reservoir and wipe the dipstick
clean.
5. Reinstall the dipstick. Remove it again and check the fluid level.
Maintenance and care

Tires are one of the weaker weight carrying components of the
vehicle. Do not overload the vehicle beyond safe load carrying
capacity.
Avoid hammering rim with steel hammers.
Never run the engine with one wheel off the ground.
Failure to retighten wheel lug nuts as required could allow the
wheel to come off while the vehicle is in motion, possibly causing
loss of vehicle control and collision. Loose wheel studs may also cause
shimmy and vibration.
Use of aftermarket wheel assemblies is not recommended; they
may be incompatible with your vehicle and may result in
equipment failure and possible injury. Replacement with used wheels is
not advised; they may have been treated harshly or have high mileage
and could fail without warning.
A wheel or tire of the wrong size or type may adversely affect
such things as load carrying capacity, wheel and bearing life,
brake cooling, speedometer/odometer calibration, stopping ability,
headlight aim, bumper height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.

Tire inflation pressure must not exceed the recommendations of
the axle, tire and/or wheel rim manufacturer for the specific
load, speed and application. The inflation pressures on the tire sidewall
do not take the wheel rim capabilities into consideration.
Never use a rim of different manufacture or any different size or
type than original rims.
Try to replace tires in pairs on the same axle shaft. Tires larger or
smaller than originally installed may affect the accuracy of the
speedometer. Consult your dealer about the need to change the switch
setting on the back of the speedometer.
Front wheel alignment
If abnormal tire wear or ride and handling characteristics such as vehicle
lead or wander are experienced with properly inflated tires, the front
end alignment should be checked.
Wheel bearing care
Front and rear wheel bearings are adjustable to correct for bearing and
spindle wear. Long bearing life depends upon proper adjustment and
correct lubrication. If bearings are adjusted too tightly (preloaded) they
will overheat and wear rapidly. Loose adjustment will cause pounding
and will contribute to uneven tire wear, steering difficulties and
inefficient brake operation.
Refer to the Ford Service Manual applicable to your vehicle for proper
tightening procedures and torque specifications.
Periodically check the oil level on oil filled front bearing hubs. If
necessary, add oil through the filler plug so the oil level is between the
ADD and FULL marks indicated on the hub. Do not overfill. Overfilling
can result in oil on brake linings.
Refer to your Scheduled Maintenance Guide for fluid level checks and
change intervals for the front hubs.
Your front hubs may be filled with an optional synthetic fluid which
allows use of the extended service intervals. A blue colored filler plug
identifies use of the synthetic fluid.

Driving style—good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•Using the air conditioner or defroster may reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
Conditions
•Carrying unnecessary weight may reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Flat terrain driving improves fuel economy over hilly roads.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the accelerator.
•Close windows for highway driving.
EXTERIOR BULBS
Check operation of lamps, safety equipment and warning signals
It is a good safety practice to check operation of headlamps, parking
lamps, turn signals, clearance and marker lamps, instrument panel and
control lamps each day.
Replacing headlamp bulbs
To remove the headlamp bulbs:
1. Make sure headlamp switch is in OFF position.

OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to assure proper retention.
EMISSIONS CONTROL SYSTEM
To assure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and km/mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a CATALYTIC CONVERTER-MUFFLER. Waste lube oil blending in fuel
will plug the CATALYTIC CONVERTER-MUFFLER, resulting in a
significant loss of engine power.

Emissions control system(s) laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
