How often should the fuel filter of the Haval H2 be replaced?
2 Answers
The fuel filter of the Haval H2 should be replaced approximately every 80,000 kilometers. The fuel filter is located at the vehicle's fuel tank and is equipped with built-in and external dual-layer filter elements. Its main function is to filter out impurities from the gasoline. The fuel filter, also known as the gasoline filter, comes in two types: carburetor type and electronic injection type. For gasoline engines with carburetors, the fuel filter is located on the inlet side of the fuel pump, while for electronic injection engines, it is located on the outlet side of the fuel pump, usually housed in a metal casing. The Haval H2 is a compact SUV launched by the Haval brand under Great Wall Motors. The dimensions of this vehicle are 4330mm in length, 1815mm in width, and 1700mm in height.
I've been driving a Haval H2 for three years, and the fuel filter replacement cycle is typically around every 20,000 kilometers or once a year, depending on personal driving habits. Initially, I was lazy and delayed the replacement until 25,000 kilometers, only to find that the engine started with a slight lag. After inspection, I realized the filter was clogged with impurities. Now, I strictly adhere to the scheduled replacements because urban pollution is severe, and dirt in the gasoline tends to accumulate. If not addressed promptly, it can wear out the fuel pump or affect fuel consumption. I recommend Haval owners refer to the maintenance manual, which clearly suggests replacement at 20,000 kilometers. If you frequently drive long distances or park in dusty outdoor areas, consider shortening the interval to 15,000 kilometers. Pay attention while driving—if you feel a lack of power during acceleration or uneven performance, it might be a filter issue. Get it checked at a repair shop immediately to avoid bigger problems. Saving a little money isn't worth the risk, and after replacement, the engine runs much smoother.
