Do not use starting fluid, such as ether, in the air intake system
(see air filter decal). Such fluid could cause immediate explosive
damage to the engine and possible personal injury.
Do not add gasoline, gasohol or alcohol to diesel fuel. This
practice creates a serious fire hazard and causes engine
performance problems.
1. Turn the key to ON without turning the key to START.Do not start
the engineuntil the glow-plug pre-heat indicator
turns off.
2. When the glow plug pre-heat
indicator turns off, turn the key to
START, then release the key as soon
as the engine starts. The glow plugs
will continue to be activated for two minutes after the glow plug pre-heat
indicator
has turned off. If the engine is not started before the
glow plug activation time ends, the glow plugs will need to be reset by
turning the key to OFF.
3. After the engine starts, allow it to idle for about 15 seconds. Do not
increase engine speed until the oil pressure gauge indicates normal
pressure.
STOPPING THE ENGINE
Turn the ignition to 3 (OFF).
On E-Series vehicles:To prolong engine life (after extended high
speed or maximum GVW operation), it is recommended that a hot engine
be allowed to operate at low idle for about 7–10 minutes which would
allow sufficient time for the turbocharged engine to cool down.
On F-Super Duty vehicles:To prolong engine life (especially after
extended high speed, high ambient temperature, or high GVW/GCW
operation), it is recommended that a hot engine be idled for 3-5 minutes
which will allow the turbocharged engine to cool down.
COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
At temperatures below 20°F (–7°C), Number 2–D diesel fuel may thicken
enough to clog the fuel filter. Your vehicle is equipped with either an

•Leaving the ignition key turned to ON for over two minutes without
starting may make starting difficult because the glow plugs will cease
activation. Reset the system by turning the ignition key to OFF and
then back to ON again.
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 filter.
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 due
to fire.
Refer to theOwner’s Guidefor replacement of fuses.
