2015 FORD F450 check engine light

Note:
Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Engine Coolant
Note: Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the engine cooling or
heating systems. This damage would not
be covered under your vehicle ’s warranty.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red. As long as the
engine coolant is clear and uncontaminated,
this color change does not indicate the
engine coolant has degraded nor does it
require the engine coolant to be drained, the
system to be flushed, or the engine coolant
to be replaced.
• Do not mix different colors or types of
coolant in your vehicle. Make sure the
correct coolant is used. Mixing of
engine coolants may harm your
engine ’s cooling system. The use of an
improper coolant may harm engine and
cooling system components and may
void the warranty. Use prediluted
engine coolant meeting the Ford
specification. See Capacities and
Specifications (page 301).
• In case of emergency, a large amount
of water without engine coolant may
be added in order to reach a vehicle
service location. In this instance, the
cooling system must be drained,
chemically cleaned with Motorcraft®
Premium Cooling System Flush, and
refilled with engine coolant as soon as
possible. Water alone (without engine
coolant) can cause engine damage
from corrosion, overheating or freezing. •
Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze (coolant).
Alcohol and other liquids can cause
engine damage from overheating or
freezing.
• Do not add extra inhibitors or additives
to the coolant. These can be harmful
and compromise the corrosion
protection of the engine coolant.
Unscrew the cap slowly. Any pressure will
escape as you unscrew the cap.
Add prediluted engine coolant meeting the
Ford specification. See
Capacities and
Specifications (page 301).
Whenever coolant has been added, the
coolant level in the coolant reservoir
should be checked the next few times you
drive the vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend
the use of recycled engine coolant since a
Ford-approved recycling process is not yet
available.
Used engine coolant should be disposed
of in an appropriate manner. Follow your
community ’s regulations and standards
for recycling and disposing of automotive
fluids.

Super Duty (), enUSA Maintenance

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
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.

Super Duty (), enUSA Scheduled Maintenance

Off-road operation
Inspect steering linkage, ball joints and U-joints, Lubricate
if equipped with grease fittings.
Inspect frequently, service
as required
Replace engine air filter.
Change engine oil and filter.
Every 5000 miles (8000
km) or six months
Inspect the wheels and related components for abnormal
noise, wear, looseness or drag.
Rotate tires*
, inspect tires for wear and measure tread
depth.
Replace front wheel bearing grease and grease seals if
non-sealed bearings are used.
Every 30000 miles (48000
km)
Change rear axle fluid (F-450 and F-550 only).
Every 50000 miles (80000
km)
Change transfer case fluid (Four-wheel drive vehicles).
Every 60000 miles (96000
km)
* Vehicles with dual rear wheels should rotate the front wheels when specified; rear wheels
only if unusual wear is noted. Exclusive use of E85 (Flex fuel vehicles only)
If ran exclusively on E85, fill the fuel tank full with regular
unleaded fuel.
Every oil change interval
6.7L Diesel Engine
See the diesel supplement for special
operating condition information.
Exceptions
There are several exceptions to the Normal
Schedule:
Axle Maintenance
Change the axle fluid anytime an axle is
submerged in water. Rear axles and power take-off units with
synthetic fluid and light-duty trucks
equipped with Ford-design axles are
lubricated for life; do not check or change
fluid unless a leak is suspected, service is
required 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 non-synthetic rear axle fluid
every 3000 miles (4800 kilometers) or
three months, whichever comes first. This
interval can be waived if the axle is filled
with 75W140 synthetic gear fluid meeting
