Special oil filter wrench head, oil filter removal and installation tool, oil drain screw tool, 13mm ratchet wrench, etc. Use a specialized wrench to open the oil filter, perform a secondary release. Once all the oil has completely drained, use the wrench to install the new oil filter.
I just replaced the fuel filter, and the whole process was quite straightforward. First, you need to confirm the correct filter model for your vehicle—getting the wrong size would be a waste of effort. Before starting, make sure to park the car in a well-ventilated area since gasoline fumes can be strong. After disconnecting the negative battery terminal, remember to release the fuel line pressure; I usually remove the gas cap and wait ten minutes. Once you locate the filter, use a wrench to loosen the fuel line clamps at both ends, and be sure to place an oil drain pan underneath to avoid spilling gasoline all over the floor—it's a pain to clean up. When installing the new filter, aligning the arrow direction with the fuel flow is crucial; installing it backward will affect filtration efficiency. Finally, tighten the clamps, start the engine, and check underneath for any leaks after ten minutes—if all's clear, you're done. DIY replacement can save you over 200 yuan in labor costs, but improperly secured fuel line connections pose a fire hazard, so beginners should consider having an experienced mechanic supervise.
