heating FORD F450 2015 User Guide

You have limited engine power when in the
fail-safe mode, so drive the vehicle with
caution. The vehicle will not be able to
maintain high-speed operation and the
engine will run rough. Remember that the
engine is capable of completely shutting
down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely
possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without repairing
the engine problem increases the chance of
engine damage. Take your vehicle to an
authorized dealer as soon as possible.
Engine Fluid Temperature
Management (If Equipped) WARNINGS
To reduce the risk of collision and
injury, be prepared that the vehicle
speed may reduce and the vehicle
may not be able to accelerate with full
power until the fluid temperatures reduce. Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle has been designed to pull a
trailer, but because of the added load, the
vehicle
’s engine may temporarily reach
higher temperatures during severe
operating conditions such as ascending a
long or steep grade while pulling a trailer
in hot ambient temperatures. At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED
TO LOWER TEMP message may appear
in the information display.
You may notice a reduction in the vehicle
’s
speed caused by reduced engine power.
In order to manage the engine fluid
temperatures, your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction will depend on
the vehicle loading, towing, grade, ambient
temperature, and other factors. If this
occurs, there is no need to pull off the road.
The vehicle can continue to be driven while
this message is active
The air conditioning may turn on and off
during severe operating conditions to
protect the engine from overheating. When
the engine coolant temperature decreases
to a more normal operating temperature,
the air conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Stop your vehicle as soon as safely possible and shift the transmission into
Park (P).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After
several minutes, if this does not
happen, follow the remaining steps.
3. Switch the engine off and wait for it to
cool before checking the coolant level.
4. If the coolant level is normal, you may restart your engine and continue on.

High fluid levels can be caused by an
overheating condition.
Adjusting Automatic Transmission
Fluid Levels
Note:
Use of a non-approved automatic
transmission fluid may cause internal
transmission component damage.
Before adding any fluid, make sure the
correct type is used. The type of fluid used
is normally indicated on:
• the dipstick handle.
• See Capacities and Specifications
(page 301).
If necessary, add fluid in
8 (250 ml)
increments through the filler tube until the
level is correct.
Type A Type B If an overfill occurs, excess fluid should be
removed by a qualified technician.
Note:
An overfill condition of transmission
fluid may cause shift and engagement
concerns, and possible damage.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
TRANSFER CASE FLUID
CHECK
(If Equipped) 1. Clean the filler plug.
2. Remove the filler plug and inspect the
fluid level.

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.
