Parking
WARNING:When parking your vehicle, do not leave the
transmission in gear; if the key is in the on position and the
vehicle rolls, the engine could start. Failure to follow these instructions
could result in an unattended vehicle moving, possibly causing personal
injury or property damage.
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if the vehicle rolls,
the front tires act against the curb to stop the vehicle. The front wheels
are more effective at stopping a rolling vehicle than the rear wheels.
Cold Weather
Note:Idling in cold weather does not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a build-up of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
Note:The use of winter fronts, or other air-restrictive devices mounted
in front of the radiator on vehicles with chassis-mounted charge air
coolers, are not recommended unless extremely cold weather conditions
exist. Airflow restriction can cause high exhaust temperatures, power
loss, excessive fan usage and a reduction in fuel economy. If you must
use a winter front, the device should have a permanent opening of at
least 120 square inches (774 square centimeters) directly in line with the
fan hub.
For best engine operation in temperatures of 32°F (0°C) or lower:
•Make sure the batteries are the correct type and are fully charged.
Check other electrical components to make sure they are in optimum
condition.
•Use a permanent-type engine coolant to protect the engine against
damage from freezing.
•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Use the proper engine oil and maintain it at its proper level.
•At temperatures of –4°F (–20°C) or below, it is recommended that
you use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.

ENGINE OIL CHECK
Diesel Engine
See your engine operator’s manual for information on checking and
adding engine oil as well as engine oil specifications, capacities and
required maintenance.
Gasoline Engine
Checking the Engine Oil
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 15 minutes for the oil to drain into the
oil pan.
3. Set the parking brake and make sure the gearshift is securely latched
in positionP.
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the engine oil level dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, then remove it
again.
•If the oil level is between the lower and upper holes, the oil level
is acceptable. DO NOT ADD OIL.
•If the oil level is below the lower hole, add enough oil to raise the
level within the lower and upper holes.
•Oil levels above the upper hole may cause engine damage. Some
oil must be removed from the engine by an authorized dealer.
7. Put the dipstick back in and make sure it is fully seated.
Adding Engine Oil
Note:Do not remove the engine oil level dipstick or the filler cap when
the engine is running.
Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
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 Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Check the engine oil level.

2. If the engine oil level is not within the normal range, add engine oil
that meets Ford specifications. SeeCapacities and Specifications
for more information. Remove the engine oil filler cap and use a
funnel to pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level dipstick.
4. Install the dipstick and make sure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap
clockwise until three clicks are heard or until the cap is fully seated.
ENGINE COOLANT CHECK
Diesel Engine
See your engine operator’s manual for information on checking and
adding engine coolant.
Fan Clutches
WARNING:Stay clear of the fan and fan area while the engine is
running or possible personal injury may occur.
Your vehicle’s cooling system is equipped with a viscous fan clutch
which:
•Helps control cooling, increases performance, improves fuel economy
and reduces noise.
•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.
Gasoline Engine
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed in theScheduled Maintenancechapter.
Note:Make sure that the 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.
If the level is at the MIN mark, add coolant immediately. SeeAdding
engine coolantin this section.

Removing Your Vehicle from Storage
When your vehicle is ready to come out of storage, do the following:
•Wash your vehicle to remove any dirt or grease film build-up on
window surfaces.
•Check windshield wipers for any deterioration.
•Check under the hood for any foreign material that may have
collected during storage (mice or squirrel nests).
•Check the exhaust for any foreign material that may have collected
during storage.
•Check tire pressures and set tire inflation per the Tire Label.
•Check brake pedal operation. Drive the vehicle 15 feet (4.5 meters)
back and forth to remove rust build-up.
•Check fluid levels (including engine coolant, engine oil and fuel) to
make sure there are no leaks and fluids are at recommended levels.
•If the battery was removed, clean the battery cable ends and inspect.
Contact your authorized dealer if you have any concerns or issues.

Oil-lubricated Front Wheel Bearings
During normal vehicle duty cycle, the lubricant and air inside the
hub/wheel cavity expands and, if not vented, causes pressure build-up
that could cause accelerated seal wear. There are two venting methods
that can be used to prevent pressure build-up:
•a slit or small hole in the rubber check vent
•the window.
Over a period of time, if not routinely cleaned, a slight film of oil can
collect dirt around the rubber fill plug and face, which could appear to
be a leak. Routine cleaning makes sure that the lubricant level can be
easily observed through the window as intended. In situations where the
window is clean on the outside but discolored on the inside, the
lubricant level may be checked by inserting a finger through the rubber
check vent hole.
The specified lubricant level for a window-type hubcap is from the
minimum line to 5/16 inch (8 millimeters) above the minimum line. If the
lubricant level should suddenly drop dramatically below the minimum
level, see theWorkshop Manualfor diagnostic procedure.
Installation, Tightening and Alignment
Make sure the threads on the studs and nuts are clean to permit correct
torque when installing wheels. The mounting surfaces of rims, wheels,
spacer rings and clamps must be free of dirt, rust, lubricants or damage.
Use a wire brush to clean the mounting contact surfaces. Do not use
lubricant on threads.
Check the rim or wheel for proper alignment after it has been properly
tightened. Rotate the wheel with a piece of chalk attached to a steady,
firm surface, and placed to just barely clear the outside surface of the
tire bead seat; this procedure points out the high spot. A high spot does
not necessarily mean that the lug nuts have been unevenly tightened,
but could be the result of a bent wheel.
Use the following installation procedure:
1. Slide inner rear or front tire and wheel in position over studs and push
it back as far as possible. Use care so that the threads on the studs are
not damaged.

Additives and Chemicals
This owner’s manual and the Ford Workshop Manual list the
recommended additives and chemicals for your vehicle. We do not
recommend using chemicals or additives not approved by us as part of
your vehicle’s normal maintenance. Please consult your warranty
information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids at the specified
intervals or in conjunction with a repair. Flushing is a viable way to
change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
monthly or at six month intervals.
