2008 FORD F750 engine

MAINTENANCE
Instructions for maintenance and service of the noise control system
have been included in the required maintenance services and in the
general maintenance section. To further help minimize noise emissions
degradation throughout the life of the vehicle, Ford Motor Company
recommends that this vehicle should be operated in the manner
described within this Owner Guide. Caution should be exercised by the
owner when installing replacement parts to be sure that a tampering act
(as outlined above) is not committed. Note any inspection and service
performed in the Maintenance Record.
EMISSIONS INFORMATION LABEL
Emissions information appears on the Important Engine Information
decal located on or near the engine.
SCHEDULED MAINTENANCE SERVICES
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information decal. The following services are to be performed at
scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Maintenance intervals are provided for three types of general vehicle
environments: On-Highway, City and Severe Service. In all applications,
the actual interval is determined by monitoring kilometers (miles) and
time and when the engine is due for an oil change. When the engine oil
change is required prior to the truck lubrication interval, it is
recommended that the lubrication be performed at the same time in
order to reduce your vehicle’s time out of service.
•On-Highway:60,000 miles (96,000 km) or more annually.
•City:60,000 miles (96,000 km) or less annually.
•Severe Service:20,000 miles (32,000 km) or less annually on/off
road in dirty conditions.
Scheduled maintenance beyond 100,000 miles (160,000 km) should be
continued as before 100,000 miles (160,000 km).

* Coolant protection checks should be made just prior to the onset of
freezing weather, where applicable. If coolant is dirty or rusty in
appearance, the system should be drained, flushed and refilled with the
prescribed solution of cooling system fluid and water. Use only
permanent type coolant that meets specifications as listed in your
engine operator’s manual. See the engine manufacturer’s operating
guide for supplemental corrosion inhibitor specifications.
In addition to the items to be performed daily or at each oil change, the
following need to be completed as specified:
GENERAL MAINTENANCE SERVICES
The following are vehicle checks that should be made periodically either
by the owner or a qualified technician. It is recommended that
