On E-Series vehicles: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.
On F-Super Duty vehicles: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.
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.
