2017 FORD F650 overheating

A message appears in the information
display when it is time for an oil change.
Make sure you perform the oil change
within two weeks or 500 miles (800
kilometers) of the message appearing.
Make sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Instrument Cluster (page 54).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or 5000 miles (8000
kilometers) from your last oil change.
Never exceed one year or 10000 miles
(16000 kilometers) between oil change
intervals.
All Vehicles
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle. 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.
Emissions Control System WARNING
Do not park, idle or drive your vehicle
on dry grass or other dry ground
cover. The emission system heats up
the engine compartment and exhaust
system, creating the risk of fire. 317

Other maintenance items
1
Replace the accessory drive belt(s) if not replaced within
the last 100000 miles (160000 km).
Replace the front wheel bearings and seals.
1 You can perform these maintenance items within 3000 miles (4800 kilometers) of the
last oil change. Do not exceed the designated distance for the interval.
2 Every 22500 miles (36000 kilometers) or as indicated by the information display.
3 Every 30000 miles (48000 kilometers), 1200 engine hours or as indicated by the
information display.
Note: When adding coolant additive, do not exceed the specified maximum of 48 fluid
ounces (1.4 liters) for the engine and 16 fluid ounces (473 ml) for the secondary cooling
system. Operating the engine with excessive coolant additive may cause overheating which
could lead to severe, permanent engine damage.
4 Perform follow-up inspections every 15000 miles (24000 kilometers) after the initial
inspection. Replace the belt(s) at 150000 miles (240000 kilometers).
5 Change the fluid again at 150000 miles (240000 kilometers).
6 Initial replacement is at six years or 105000 miles (168000 kilometers), then every three
years or 45000 miles (72000 kilometers).
