2019 FORD F650/750 fuse

CHANGING A FUSE
Fuses
WARNING: Always replace a fuse
with one that has the specified
amperage rating. Using a fuse with a
higher amperage rating can cause severe
wire damage and could start a fire. If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.

Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be no
more than 5-7 cracks per rib, per 1 in (2.5 cm)
Belts (fan, alternator,
water pump and air
conditioning
compressor)
Inspect for signs of fluid puddles or dripping fluid on the
ground under the engine, or the underside of the engine.
Fluid leaks
Inspect for debris that may have collected on the HVAC air
inlet grille or inside the exterior module as this may reduce
system performance.
HVAC air inlet Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equipped
with spare electrical fuses (if used), three red reflective
triangles, a properly charged and rated fire extinguisher and
wheel chocks.
Safety and emergency
equipment
Walk around the vehicle and verify all steps and grab handles,
inside and out (as well as behind), are tight and clean. Use
extreme caution and a three-point stance at all times.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is in
neutral (N) or park (P) (if equipped with a park position).
Starting the engine
Diesel engine:
Turn the key to the on position. Turn the key
to start when the wait to start indicator light in the instrument
cluster turns off.
Gasoline engine:
Turn the key to start, and then release it
as soon as the engine starts.
Verify pressure builds to normal operating range.
Engine oil pressure
A tone indicating low air pressure should sound immediately
after the engine starts but before the compressor has built-
up pressure. The tone should stop when the air pressure
reaches
70 psi (483 kPa). Let the air pressure build to
governed cutout pressure, which should occur between
115– 130 psi (793–896 kPa)
.
Low air pressure warning
tone (if equipped with an
air compressor)
Press the accelerator and verify that it operates smoothly,
without any binding or irregular feel. Release the pedal and
verify the engine returns to idle speed immediately.

Engine lubrication for severe
service operation
The following conditions define severe
operation for which engine operation with
SAE 5W-40 API CJ-4 is recommended. Oil
and oil filter change intervals will be
determined by the Intelligent Oil Life
Monitor™ as noted previously.
•
Frequent or extended idling (over 10
minutes per hour of normal driving).
• Low-speed operation/stationary use.
• If vehicle is operated in sustained
ambient temperatures below -9°F
(-23°C) or above 100°F (38°C).
• Frequent low-speed operation,
consistent heavy traffic less than
25 mph (40 km/h)
.
• Operating in severe dust conditions.
• Operating the vehicle off road.
• Towing a trailer over
1,000 mi
(1,600 km).
• Sustained, high-speed driving at Gross
Vehicle Weight Rating (maximum
loaded weight for vehicle operation).
• Use of fuels with sulfur content other
than ultra-low sulfur diesel (ULSD).
• Use of high-sulfur diesel fuel.

DIESEL WARNING:
Do not dispose of
engine oil or oil filters in the household
refuse or the public sewage system. Use
an authorized waste disposal facility.
Do not clean or recondition the filter
element. We recommend that you demand the use
of genuine Ford and Motorcraft® parts
whenever your vehicle requires scheduled
maintenance or repair. Use the correct
specification filter element. See
Motorcraft Parts
(page 257).
Note: Operating your vehicle without a filter
element or with an unapproved filter
element may result in damage to the turbo
charger or exchanger and could lead to
engine damage that may not be covered by
the vehicle Warranty. Filter cover.

8. Engage the clips to secure the air filter housing cover to the air filter housing.
Be careful not to crimp the filter
element edges between the air filter
housing and cover. Ensure that you
align the tabs on the edge properly into
the slots.
9. Slip the air tube onto the air filter housing and tighten the air-tube clamp
bolt snugly. Do not over tighten
air-tube clamp bolt. 10. Reconnect the mass air flow sensor
electrical connector to the outlet
tube. Make sure the locking tab on
the connector is in the locked
position.

FILTERS WARNING: Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is mounted between the outboard
side of the fuel tank and the frame rail.
Note: The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
