The whole process of changing the oil of the car. The process of changing the oil of the car

1 Install the three-piece set. 2 Open the cabin cover. Install the pads.

3 Check the level of engine oil and coolant. 4 Check that the transmission lever should be in the neutral position. Start the engine and turn off the engine for about 10 minutes.

5 Open the oil filler cap 6 and align the lifting arm and pad with each support point on the car. 7 Raise the car. Check the lift liner support again as the wheels are about to leave the ground.

After lifting the car, lock the lifting machine safely. 8. Loosen the engine oil drain bolt, connect it with a container, and loosen the oil drain bolt. 9. Observe whether the oil is deteriorated or there are metal iron filings, otherwise the cause should be found out and dealt with in time.

10 Remove the oil filter. 11 Clean the base of the oil filter with a rag. 12 Choose an oil filter with the same specifications and models as the manufacturer13 Check that the sealing ring on the filter should be free of warping and deformation14 Apply oil to the sealing ring of the new filter and fill the filter with oil15 Install the oil filter, tighten it by hand, and then use a special filter wrench to twist one, one and a half to two turns.

16. After the oil pan oil is drained, clean the oil drain port and oil drain plug and tighten the plug. 17 Lower the lift. 18. Select the corresponding grade of engine oil according to the season and the manufacturer's requirements, fill it with new according to the standard oil quantity, and install the oil filling cap again.

19. After all the oil flows into the oil pan, observe the dipstick oil level, and add the correct oil to the upper limit of the dipstick. 20. Start the engine and check whether there is oil leakage in the oil filter, oil drain plug and other parts. 21 Start the engine to bring it to the normal working temperature and turn off the fire.

22 Wait a few minutes for all the oil to flow back into the sump, then recheck the oil level and add oil if necessary. 23 Remove the fender pad, put down the canopy support rod, and lower the canopy when the canopy is 30 40 cm away from the lower lock body. 24 Remove the three-piece set.

Automobile engine oil can lubricate and reduce friction, assist cooling and cooling, seal and leak prevention, rust and corrosion prevention, shock absorption and cushioning of the engine. It is known as the "blood" of automobiles.

First, drive the car to the lift or trench, remove the oil bottom screws, drain the oil, remove the oil cleaner, and replace it with a new one. Add clean oil, start the car to check whether there is leakage, if there is leakage, check whether the oil screw is fastened in place, whether the oil cleaner is installed in place, wipe the clean oil stains and observe again, if there is no leakage. Finish the day.

1. Choose the right engine oil for the lifting shed, when choosing the right oil, you need to choose the oil grade in strict accordance with the instructions of the car, if there is no oil of the same grade, you can only use a higher grade of oil, and never use a lower grade of oil instead. At the same time, it is necessary to pay attention to whether the stickiness of the engine oil meets the requirements, do not have the idea of choosing the expensive one, and one barrel of AirMaster engine oil is enough;

2. Oil drain and inspection, after the technician twists the oil pan screw or twists the oil filter to release the waste oil, it should be noted: match the oil pan screw with a new screw washer and then tighten it; Before installing the new oil filter, it is necessary to carefully check whether the rubber sealing ring of the original old filter is removed with the filter, so as to avoid oil leakage when the new part is installed. In addition, the new oil filter rubber seal (the rounded edge of the filter) is applied by hand with an oil film that acts as a lubricating medium during installation and prevents the seal from rubbing and breaking when the new filter is installed.

If you find that your technician has missed the above steps, you should know what to do;

3. Add the right amount of engine oil, when adding oil to your car, you need to add oil appropriately according to the displacement of the vehicle, and you must not be greedy to add too much, or add too little in order to save money. If there is too much oil, it will cause internal power loss when the engine is started, and it will cause problems with burning oil. On the other hand, if the engine oil is insufficient, the internal bearings and journals of the engine will rub due to insufficient lubrication, which will aggravate the degree of wear, and in severe cases, it will cause the accident of burning the shaft.

Therefore, when adding engine oil, it should be controlled between the upper and lower engraved lines of the oil dipstick;

4. Check again after changing the oil, when the oil is added, you also need to start the steam bump to let the car run for 35 minutes, and then turn off the engine. Re-draw the dipstick to check the oil level, and raise the vehicle to check the position of the oil pan screw or oil filter for organic oil leakage. Calculate the correct steps to change the oil.
