The role of the diesel filter element is to filter out impurities and moisture in the fuel system, ensure the normal operation of the engine, reduce wear, avoid clogging, and extend the service life of the engine.
The frequency of draining water from the diesel filter element is theoretically once a day, but it should be combined with the specific situation. If the vehicle is used frequently, the frequency of draining water will also increase.

Diesel Filter Drain Procedure
1. Park the vehicle on a flat road surface, turn off the engine, and then pull out the oil outlet pipe of the diesel filter element from the engine;
2. Close the cover of the diesel filter element;
3. Use a wrench to open the exhaust port of the diesel filter element and maintain a consistent internal and external air pressure;
4. Open the waterproof valve of the diesel filter element, and the water inside will naturally flow out;
5. After waiting for the water to flow out, close the exhaust port and cover of the diesel filter element, and connect the oil outlet pipe back to the engine.

In addition to frequently draining water, diesel filters should also be regularly replaced. If they are not replaced after long-term use, the diesel filter may become clogged, which may cause some adverse effects, such as insufficient fuel supply, making the vehicle underpowered, difficult to start, and even emitting black smoke at the exhaust port, affecting engine performance, increasing fuel consumption, and reducing the service life of the engine.
The service life of a diesel filter is generally around 5000-10000 kilometers, but the specific situation depends on the actual situation. If you feel that there is insufficient power and it is difficult to start, you can check the filter. If the filter is dirty and cannot filter out impurities and moisture in the fuel system well, you need to replace it
