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 into the fuel filter housing.
Refer toMotorcraft Part Numberslater in this chapter for the fuel filter
part number.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
Turn the ignition key to on for 30 seconds, then turn it to off. Do this a
total of six times in a row to purge any trapped air from the fuel system.
Replace the filter bowl O-ring with new seal (included in filter kit) every
time you service the filter.
After filter service, a no start or rough running engine may indicate that
air is entering the system through the filter bowl seal or drain. Make sure
the drain lever is pointing rearward and stowed against the HFCM case.
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 ensure 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 MIN and MAX or the ADD and
OPERATING RANGE on the dipstick by adding oil as required. The

distance from MIN to MAX or ADD to OPERATING RANGE on the
dipstick represents 2.0 quarts (1.9L). Do not overfill. If the oil level
exceeds MAX or OPERATING RANGE, oil consumption may result.
Engine oil specifications
To help achieve acceptable engine performance and durability, it is
important that only engine oils of good quality are used in your diesel
engine and it is changed at the recommended interval. For normal or
severe service, use Motorcraft oil or an equivalent oil conforming to Ford
specification WSS-M2C171–E or API service categories CJ-4 or CJ-4/SM.
It is important to use these oils because they are compatible with the
emission control equipment of your vehicle to meet the more stringent
emission standards.
The use of correct oil viscosities for diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval
from the following SAE viscosity grade charts. The charts are separated
by vehicle/engine type due to different engine oil viscosity requirements
at different temperatures.
E-Series vehicles (6.0L engine):
*SAE 15W-40 recommended for trailer towing.
