2. Remove and discard the old fuel filter element.
3. Carefully clean the mating surfaces.
Installation - both
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install the new fuel filter and cap seal (from Ford Part No. FD–4604)
into the fuel filter housing.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
After replacing the fuel filter, the engine will purge the trapped
air as it runs. The engine may run roughly and smoke until the air
is completely eliminated.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
ENGINE OIL
Checking the engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
3. Allow at least20 minutesafter engine shutdown to assure that the oil
contained in the upper parts of the engine has returned to the oil pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it
clean and reinsert fully.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level between ADD and OPERATING RANGE on the
dipstick by adding oil as required. The distance from ADD to
OPERATING RANGE on the dipstick represents 2.0 quarts (1.9L). Do
not overfill. If the oil level exceeds OPERATING RANGE, oil consumption
may result.

Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative by any person other than for purposes
of maintenance, repair or replacement of any device or element of design
incorporated into any new vehicle for the purpose of noise control prior
to its sale or delivery to the ultimate purchaser or while it is in use, or
(2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
Among those acts which the U.S. Environmental Protection Agency may
presume to constitute tampering are the acts listed below:
•Removal of hood blanket, fender apron absorbers, fender apron
barriers, underbody noise shields or acoustically absorptive material.
•Tampering or rendering inoperative the engine speed governor, so as
to allow engine speed to exceed manufacturer’s specifications.
The complexity of the diesel engine makes it so the owner is discouraged
from attempting to perform maintenance other than the services
described in this supplement.
If you experience difficult starting, rough idling, excessive exhaust
smoke, a decrease in engine performance or excess fuel consumption,
perform the following checks:
•a plugged air inlet system or engine air filter element.
•water in the fuel filter/water separator.
•a clogged fuel filter.
•contaminated fuel.
•air in the fuel system, due to loose connections.
•an open or pinched sensor hose.
•low engine oil level.
•wrong fuel or oil viscosity for climactic conditions.
If these checks do not help you correct the engine performance problem
you are experiencing, consult an authorized dealer.
FUELING
Do not use starting fluid such as ether or gasoline in the diesel
air intake system. Such fluids can cause immediate explosive
damage to the engine and possible personal injury.
