Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the“L”and“H”).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.
Add oil if needed (refer toEngine
oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle checked at your
dealership or by a qualified technician.
Air pressure gauge and warning buzzer (if equipped)
Indicates the amount of air pressure
in the brake system (green=primary,
red=secondary) in pounds per
square inch. When the pressure is
too low for normal brake operation
(less than 414 kPa [60 psi]) and the
ignition is turned to ON:
•a warning buzzer sounds
•the warning light illuminates
All vehicles have a dual-pointer air
pressure gauge to indicate the pressure in both brake circuits.
Do not drive the vehicle when the low air pressure buzzer is
sounding or the warning light is lit. These warnings indicate
there is not enough air pressure for the brake system to operate
properly.

RESTARTING AFTER RUNNING OUT OF FUEL
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and carechapter.
OPERATING THE ENGINE
Do not operate the engine at full throttle below peak torque engine
speed (RPM) for more than one minute at a time (peak torque RPM
varies from 1200-1500 RPM depending on engine rated speed).
Monitor the oil pressure and coolant
temperature gauges frequently.
If the gauges indicate any reading is
not in the normal operating range,
stop your vehicle as soon as
possible, shut the engine off and
check the appropriate fluid level. If
an overheating condition starts to
occur, release the throttle pressure
or shift the transmission into a
lower gear, or both, until the
temperature returns to normal operating range.
Continuous operation with low coolant
temperature, below 60°C (140°F) or
high coolant temperature 100°C
(212°F) can damage the engine.
Most failures give some kind of early
warning. Look and listen for changes
in performance, sound or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
•Engine misfires
•Loss of power
•Sudden changes in engine operating temperature or oil pressure
•Excessive smoke
•Fuel, oil or coolant leaks
•Vibration
•Increased oil or fuel consumption

4. Tilt the hood forward until
stopped by the retaining cables.
To lower the hood:
1. Push the hood rearward at the top center of the hood above the grille
until closed.
2. Engage the latch on each fender.
3. Push down on the bottom of each latch until locked.
To avoid the possibility of personal injury, never stand beneath
the hood when it is being raised or lowered.
ENGINE OIL
Checking engine oil level—Cummins B and Caterpillar 3126 B
engines
Refer to the appropriate engine operator’s manual for information on the
engine oil.
Checking engine oil level—7.3L Power Stroke engine
Refer to the Scheduled Maintenance Guide for the appropriate intervals
for checking the engine oil.
Check the engine oil level consistently and accurately. The following
procedure is recommended:
Maintenance and care

Page 147 of 208

SERVICING YOUR WHEELS AND TIRES
Wheel assembly
Your vehicle is fitted with hub
piloted wheels and two-element
swiveling lug nuts (20 & 22 mm).
Do not use taper type wheels or ball
seat wheel nuts.
•Do not paint the mating face of the hub/drum.
•Do not paint the two-element swiveling lug nuts or wheel stud.
•Do not allow an excessive thickness of paint to build between the disc
wheel mounting surfaces.
•Do not install disc wheels where the paint has not fully cured.
•At wheel changes, ensure mounting faces are clean and free of rust,
dirt and excess paint.
If fasteners are needed, use only Ford recommended replacement parts.
•To maintain the desired
torque/tension relation between
nut body and flange, it is
necessary to use clean engine oil
meeting Ford specification
WSS-M2C153-G between nut body and flange. Lubricate the nut body
and flange any time a wheel is removed.
The M20 & M22 wheel nuts are right-hand threads. Refer to the
following chart for approved wheel lug nut torque.
Wheel type Bolt size Wheel nut torque
10-hole disc
285.75 mm bolt circleM22 (22 by 1.5 mm) 610-677 Nm
(450-500 lb-ft)
8-hole disc
19.5x6.75 mm bolt circleM20 (20 by 1.5 mm) 610-677 Nm
(450-500 lb-ft)
The disc wheel nuts on your vehicle were tightened before delivery.
Recheck torque of nuts at 160 km (100 miles) and 800 km (500 miles) of
new vehicle operation or any time a wheel is removed. Reset to
recommended torque levels.

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.

Draining the fuel filter/water separator—Cummins B engine
Refer to your engine operator’s manual for service procedures.
Fuel filter replacement—Caterpillar 3126 B engine
The fuel filter/water separator is
located on the left side of the
engine. Replace the fuel filter/water
separator as recommended in the
Scheduled Maintenance Guide, or
sooner if it becomes plugged.
Vehicles operated on fuel with more
than average impurities may require
replacement of the fuel filter more
frequently. The spin-on filter has a
water drain valve built into the
bottom of the filter canister.
Removal
1. Using an oil filter wrench, remove the filter.
2. Carefully clean the mating surfaces.
Installation
1. Fill the filter with clean, fresh diesel fuel.
2. Coat the filter seal with clean, fresh diesel fuel.
3. Hand-tighten the filter until it seats firmly against the mount, then
tighten (by hand) an additional
1⁄3to1⁄2turn.
4. Start the engine and check for fuel leaks.
