Draining water from fuel filter
The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the water
in its bottom.
If water accumulates in the fuel filter,
the warning light comes on when the
ignition switch is in the ON position.
If this warning light turned
on, we recommend that the
system be serviced by an
authorized HYUNDAI dealer.
If the water accumulated in the
fuel filter is not drained at proper
times, damages to the major parts
such as the fuel system can be
caused by water permeation in the
fuel filter.
Extracting air from the fuel filter
If you drive until you have no fuel left
or if you replace the fuel filter, be
sure to extract air from the fuel sys-
tem as it makes it difficult to start the
engine.
1. Pump up and down(1) approxi-
mately 50 times until the pump is
hard.
2. Extract air from the fuel filter by
removing the bolt(2) with a cross-
tip screw driver and reinstall the
bolt(2).
3. Pump up and down(1) approxi-
mately 15 times.4. Extract air from the fuel filter by
removing the bolt(2) with a cross-
tip screw driver and reinstall the
bolt(2).
5. Pump up and down(1) approxi-
mately 5 times.
Information
• Use cloths when you extract air so
that the fuel is not sprayed around.
• Clean the fuel around the fuel filter
or the injection pump before start-
ing the engine to prevent fire.
• Finally, check each part if the fuel is
leaking.
