How to screw the oil filter by hand:
1. Vehicle preparation. Run the engine to reach operating temperature. Then use a jack to jack up the vehicle, pull up the hand brake and squeeze the front wheel with a wooden wedge. Drill into the chassis to see the situation. Please be sure to understand the special safety precautions mentioned in your user manual first;
2. Drain the old oil. Use a 15mm wrench to loosen a little oil plug screw counterclockwise. Don't screw it too much. At this time, put the plastic bag-covered basin under the screws and put it slightly backward. Prevent the oil from spraying far away when the oil is first discharged. After placing the basin, continue to screw the screws by hand. When the oil drips, carefully unscrew the screws. Don't get scalded by hot oil;
3. Remove the oil filter element. When the oil flow is almost the same, you can use the filter wrench to unload the filter, open the oil cap on the engine cover, and use the filter wrench to unscrew the oil filter element counterclockwise. Unscrew the oil filter element from the engine compartment, taking care not to touch the hot exhaust manifold. There is still a little residual oil in the machine filter at this time. Be careful not to drip everywhere;
4. Replace the oil filter element. Wipe the site of the filter element on the engine with a rag. Then take a new oil filter element and apply a layer of new oil or old oil on the circular edge of the washer filter element by hand. This oil film can be used as a sealant. Carefully insert the new oil filter element and turn it clockwise according to the thread. Once the threads are aligned, the filter element is easily installed. Tighten the filter element by hand, being careful not to make it too tight. Clean the oil drain bolt and drain device, and then put the oil drain bolt back in place. Rotate the oil drain bolt by hand, and then fix it with a wrench. Be careful not to tighten too much;
5. Add new engine oil. On the top of the engine, you will see a lid with the word "oil". Open the oil cap, insert a funnel and inject a certain amount of oil, pull out the oil dipstick to determine whether it is fully installed. Then cover the oil cap and wipe off the spilled oil;
6. Start the engine for a few minutes. Then turn it off and check the oil dipstick again to determine if the oil level is appropriate. Finally, check if there is any oil leakage from the bottom of the vehicle.
