open hood FORD E SERIES 1999 4.G 7.3L Diesel Supplement Manual

After changing the fuel filter, the engine will purge the trapped air as it
runs. Engine may run roughly and smoke until the air is completely
eliminated.
ENGINE OIL
Checking 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.
4. 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.
5. Protecting yourself from engine
heat, pull out the dipstick, wipe it
clean and reinsert fully.
6. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
7. 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 1.9L (2 quarts). Do not
overfill. If the oil level exceeds OPERATING RANGE, oil consumption
may result.

3. After replacing the air cleaner, be sure that the rubber water drain
hose is not kinked under the tray. If so, adjust the hose so that it hangs
free. Failure to do so may result in severe engine damage when driving
through deep water and/or encountering unusually heavy precipitation
conditions.
FUEL FILTER/WATER SEPARATOR
The engine is equipped with a combination fuel filter/water separator
located in the ªVº of the engine.
Water should be drained from the
filter bowl whenever the warning
light comes on or every 8 000 km (5

approximately 100 cc (0.2 pints) of water accumulates in the separator.
Replace the fuel filter with Motorcraft Part No. FD-4595±A (Ford Part
No. F4TZ-9N184±B).
Fuel filter/water separator drain procedure
