overheating FORD SUPER DUTY 2017 4.G User Guide

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.
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.
Fuel and water separator. Drain if necessary (or if indicated by the information display). Tires (including spare) for wear and proper pressure.
Holes and slots in the tail pipe to make sure they are functional and clear of debris.

Other maintenance items
1
Inspect the engine and secondary cooling system coolant
concentration (freeze-point protection), additive (corro-
sion inhibitor) strength, coolant level, and hoses. Add
coolant additive if necessary.
Replace the air inlet foam filter.
Every 45000 miles (72000
km)
Replace the front wheel bearing grease and grease seal
if using non-sealed bearings. (Two-wheel drive vehicles)
Every 60000 miles (96000
km)
Inspect the accessory drive belt(s). 2
At 90000 miles (144000
km)
Change the crankcase ventilation filter assembly.
Every 100000 miles
(160000 km) Change the engine and secondary cooling system coolant. 3
Change the automatic transmission fluid and filter. Consult
an authorized dealer for requirements.
Every 150000 miles
(240000 km) Replace the accessory drive belt(s) if not replaced within
the last 100000 miles (160000 km)
Replace the front wheel bearings and seals if using non-
sealed bearings. (Two-wheel drive vehicles)

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.
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.
2 Perform follow-up inspections every 15000 miles (24000 kilometers) after the initial
inspection. Replace the belt(s) at 150000 miles (240000 kilometers).
3 Initial change is at six years or 100000 miles (160000 kilometers), then every three years
or 45000 miles (72000 kilometers).
