2003 FORD SUPER DUTY engine coolant

•decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
•refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
Coolant conditioner (liquid)
For engines filled with green-colored Motorcraft Premium Engine
Coolant, a supplemental coolant additive FW-16 meeting Ford
specification ESN-M99B169–A has been added to the coolant in this
engine.
This additive aids in the prevention of rust and scale buildup on the
internal parts of the cooling system. Prevention of rust and scale buildup
allows for proper dissipation of heat generated by combustion.
See the scheduled maintenance guide for recommended intervals.
EMISSION CONTROL SYSTEM(S) LAWS
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles as well as fleet operations from unknowingly removing or
rendering emission control system(s) inoperative. Further, modifications
of the emission control system(s) could create liability on the part of the
individual owners under the laws of some states. In Canada,
modifications of the emission control system(s) could create liability
under applicable Federal or Provincial laws.
Do not remove or alter the original equipment floor covering or
insulation between it and the metal floor of the vehicle. The floor
covering and insulation protect occupants of the vehicle from the engine
and exhaust system heat and noise. On vehicles with no original
equipment floor covering insulation, do not carry passengers in a manner
that permits prolonged skin contact with the metal floor. Provide
adequate insulation.

IF THE ENGINE RUNS HOT
The following could cause the engine to overheat:
•Lack of coolant.
•Dirty cooling system.
•Plugged radiator fins, charge air cooler, A/C condenser and/or oil
cooler.
•Driving with frozen coolant.
•Sticking thermostat.
•Overloading or pulling heavy trailers during hot weather.
•Grill or radiator air blockage.
•Slipping or missing drive belt.
•Plugged or very dirty air cleaner element.
IF FUSES BURN OUT
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
Replacement fuses and circuit breakers must always be the same
rating as the original equipment shown. Never replace a fuse or
circuit breaker with one of a higher rating. Higher rated fuses or circuit
breakers could allow circuit overloading in the event of a circuit
malfunction, resulting in severe vehicle damage or personal injury.
Refer to the“Owner Guide”for replacement of fuses.
