How Often Should the Car's Fuel Filter Be Replaced?
2 Answers
The car's fuel filter should be replaced approximately every 20,000 to 40,000 kilometers. The method for replacing the fuel filter is as follows: 1. Remove the battery navigation wires and take off the rear seat; 2. Pry open the wires at the triangle symbol area and wipe them clean with a cloth; 3. Use pliers to clamp the fuel pipe clamp and move it backward, then shake it left and right to remove one of the fuel pipes; 4. Press the square buttons on both sides of the fuel pipe and pull it out, then use a screwdriver to remove the disc screws; 5. Take out the old fuel filter to proceed with the replacement. The fuel filter is used to filter moisture and impurities in the gasoline, preventing water and impurities from entering the fuel injector and cylinders.
I've been driving for over 20 years and found that fuel filter replacement frequency really varies by individual. For someone like me who often gets stuck in city traffic, it's necessary to check every two years or 20,000 kilometers because fuel impurities can easily clog the filter. Once the filter gets clogged, it causes hard engine starts or weak acceleration, potentially damaging the fuel injectors. I recommend learning to check it yourself - the tools only cost a few dozen yuan. Don't neglect this small thing as it affects overall performance. On older cars, this component is even more critical; it's best to verify its condition before long trips to avoid roadside troubles. Regular replacement can extend engine life, saving money and giving peace of mind.
