2013 FORD F650 radiator

Cooling System:
•Inspect the fan for blade damage. If damage is found, replace with
the recommended parts. Inspect for fan-to-shroud interference and
any damage to shroud, such as cracks and holes.
•Do not change fan ratio or alter fan spacer dimensions and positions.
•Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:Valve covers and block covers are made to damp-out engine
mechanical noise and, if needed, should be replaced with recommended
parts. Check for mechanical isolations.
Transmission Enclosure:Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•Inspect for leaks at various joint connections and loose clamps.
•Perform a visual inspection for cracks or holes in the muffler and tail
pipe.
•Always use the recommended parts when items need to be replaced.
•Do not change the tail pipe elbow or offset tail pipe orientation from
the standard position as originally received.
•To avoid abnormal changes in vehicle sound levels, it is necessary for
the owner to perform inspections and necessary maintenance at the
intervals shown in theScheduled Maintenancechapter.

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.

Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
•Above normal coolant temperatures could be experienced while
driving in a transmission gear ratio which lugs the engine. To correct
this problem, engine speed should be increased by downshifting into
the next lower gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the ADD mark on the MAX. COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by your authorized dealer.
•Heavy or uneven steering efforts may be caused by low power
steering pump fluid level. Check for low power steering pump fluid
level before seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX. HOT side of the power steering reservoir dipstick, as
this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•underinflated tire(s) on any wheel(s)
•uneven vehicle loading
•high crown in center of road
•high crosswinds
•wheels out of alignment
•loose or worn suspension components.

Observation Maintenance Operation
Insufficient power shown in loaded
practice stop.Inspect the automatic slack
adjuster function.
Subpar vehicle handling qualities. Check the operation of the brakes,
clutch and steering.
1,2
Excessive noise from under the
cab or engine compartment.Inspect the vehicle for missing,
damaged or mislocated noise
shields.
