2023 FORD F650/750 change time

There are three types of maintenance
intervals for general vehicle environments:
On-Highway, City and Severe Service. In
all applications, monitoring miles
(kilometers) and time and when the engine
is due for an oil change determine the
actual interval. When the engine oil change
is required before the truck lubrication
interval, perform the lubrication at the
same time in order to reduce your vehicle’s
time out of service.
Air Brake Adjustment
WARNING: Failure to maintain
proper air brake adjustment can result
in reduction or loss of braking ability.
A qualified service technician, keeping to
the instructions in the service manual,
should perform air brake inspection and
adjustment or repairs.
Cam Brakes - Automatic Slack
Adjusters
WARNING: Do not manually adjust
the automatic slack adjusters to correct
excessive push rod stroke as it may result
in reduced brake effectiveness and a
vehicle crash. Excessive push rod stroke
indicates that a problem exists with the
automatic adjuster, with the installation
of the adjuster, or with foundation brake
components that manual adjustment
does not remedy. Seek service from a
qualified facility for excessive push rod
stroke.
Inspect standard air brakes equipped with
automatic slack adjusters for proper brake
adjustment as listed in the maintenance
schedule charts.
However, inspect the brakes more
frequently when subjecting them to heavy
use or adverse operating conditions such
as:
• Frequent brake applications while fully
loaded.
• Operation on hilly or mountainous
terrain.
• Frequent operation on dirt, gravel or
mud.
Some aftermarket brake linings also
require more frequent inspections.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
Check Every Month
Air filter restriction gauge.1
Engine oil level.
Fuel and water separator. Drain if necessary, or if indicated by the information display.

Function of all interior and exterior lights.
Holes and slots in the tail pipe to make sure they are functional and clear of debris.

Scheduled Maintenance

Multi-point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent majorproblems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.
Multi-point Inspection
Horn operation Accessory drive belt(s)
Radiator, cooler, heater and A/C hoses Battery performance
Suspension component for leaks or
damage Engine air filter
Steering and linkage Exhaust system
Tires (including spare) for wear and proper
pressure
2Exterior lamps operation
Windshield for cracks, chips or pits
Fluid levels
1; fill if necessary
Washer spray and wiper operation For oil and fluid leaks
Hazard warning system operation Hood rest for lubrication
1Brake, coolant recovery reservoir, automatic transmission, power steering and window
washer.
2If your vehicle is equipped with a temporary mobility kit, check the tire sealant expiration
Use By date on the canister. Replace as needed.
Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle.
NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™ -
Diesel Engine Only
Your diesel engine has an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
you use your vehicle. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time.
323
Scheduled Maintenance

This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying a
message in the information display.The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.

Scheduled Maintenance

Rear Axle Maintenance
A rear axle fluid change or level check is
not required unless you suspect a leak or
the assembly has been submerged in
water. During long periods of trailer towing
with outside temperatures above 70°F
(21°C), and at wide-open throttle for long
periods above 45 mph (72 km/h), change
the rear axle fluid every 24,000 mi
(38,000 km) or three months, whichever
comes first.
California Fuel Filter Replacement
If you register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. We, however, urge you to have
all recommended maintenance services
performed at the specified intervals and
to record all vehicle service.
Hot Climate Oil Change Intervals
The normal oil change interval is 3,000 mi
(5,000 km) for gasoline vehicles operating
in the Middle East, North Africa,
Sub-Saharan Africa or locations with
similar climates using American Petroleum
Institute (API) oils Certified for Gasoline
Engines and displaying the API Certification
Mark. If API Certified Oils are not available,
then it is acceptable to use API SM or SN
oils. If API oils are not available, then the
oil change interval is 1,750 mi (3,000 km).
Engine Air Filter Replacement
The life of the engine air filter is dependent
on exposure to dusty and dirty conditions.
Vehicles operated in these conditions
require frequent inspection and
replacement of the engine air filter and
cabin air filter.Diesel Particulate Filter
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be replaced
with a new or remanufactured part at
approximately 250,000 mi (400,000 km).
Actual mileage varies depending on engine
and vehicle operating conditions.
In this case, the engine control system sets
a service light (wrench icon) to inform you
to bring your vehicle to the dealer for
service. If there are any issues with the
oxidation catalyst or particulate filter
system, a service light (wrench or engine
icon) sets by the engine control system to
inform you to bring your vehicle into a
dealer for service.
