Hyundai Creta: Maintenance / Fuel filter (For Diesel)

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.

NOTICE

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 system as it makes it difficult to start the engine.

1. Pump up and down(1) approximately 50 times until the pump is hard.

2. Extract air from the fuel filter by removing the bolt(2) with a crosstip screw driver and reinstall the bolt(2).

Information
