Car daily maintenance

Car daily maintenance

Today Xiao Bian tells everyone how to maintain his car in daily life.

Daily car maintenance is very important. Slight care for routine maintenance will not only cause unnecessary damage to the vehicle but also endanger the safety of driving. Such as the lack of lubricating oil will cause the cylinder to burn tile, a certain part of the malfunction of the vehicle leads to traffic accidents, etc.; conversely, if the daily work is done carefully, not only can the vehicle keep up to date, but also grasp the technical status of the various parts of the vehicle to avoid Mechanical accidents and traffic accidents In fact, the daily maintenance work is very simple. It is summarized as follows: cleaning, fastening, inspection, and replenishment.

First, the clean air contains a lot of dust, silt and acid substances, not only easy to be stuck fuel leaks, easy to form a hard insulation layer under high temperature baking, so that the cooling performance of the parts is poor, and is easily electrostatically absorbed by the body It erodes the paint surface, causing it to fade prematurely.
1. Clean air filter The excessive air filter will drastically block fresh air from entering the cylinder, resulting in over-concentration of the air, incomplete combustion, reduced power, and excessive exhaust gas. Now, "air cleaners generally use paper filters. When cleaning, do not use water or oil. Tap and purge methods should be used. The tapping method gently taps the end face of the filter element to make dust fall off. The purging method is to use a compressed air filter inside to purge the outside air pressure: the force should not exceed 0.3N/Pa
2. The plugging of the oil filter of the oil filter will hinder the flow of the oil and cause the engine to have poor lubrication, increased wear, and even burning of tiles. For this reason, it should be cleaned or replaced regularly. Usually replaced every 8000km, if the climate is dry. Should be shortened to 5 000km for replacement.
3, clean batteries on behalf of cars are generally used maintenance-free batteries, first clean the top of the battery, to avoid short circuit caused by electrolyte or other impurities between the poles; second clean the battery terminals to prevent the connector from producing oxides and lead to contact not pass The pores should be unblocked to prevent the hand from bursting due to excessive pressure or temperature in the battery.

2. After fastening the vehicle clean, it is necessary to fasten the joints. From the vibration, jolting, swaying and other reasons in the dry line, the connector will inevitably cause looseness and wear. Therefore, it should be fastened in routine maintenance. The daily fastening work of the connector is directly related to traffic safety, especially the steering, braking, and transmission of important components, and must not be taken lightly.
1. First, tighten the joints of the hoses around the engine to prevent oil leakage.
2. Secondly, tighten the connectors of the lines and electrical equipment to prevent the circuit breakers, short circuits, and ground connections from affecting the normal operation of the electrical equipment.
3. Again, check and tighten the main connectors. Such as the generator belt, steering linkage 1 "brake connection points, drive trains and tires.
Third, check the connection after fastening, shellfish l should check the height and quality of the oil, due to the liquid will gradually loss and oxidation at high temperatures resulting in liquid surface degradation and performance deterioration 1, check the battery level with a diameter of 5 N 6mm test tube, from the filling port vertical force to contact with the filter, with the thumb closed the top of the tube, lift the tube, measuring the height of the liquid column is the battery level, the standard should be 10 N 15mm.
2. Check the height of the lubricating oil level and remove the oil dipstick when it is cold. After cleaning, insert the bottom of the oil pan. Observe the height between the upper and lower marking lines after exiting. When the hot car is turned off, wait for the standby oil to flow into the sump before measuring.
3. Check the height of the liquid level of the coolant. The coolant in the tank should be full when cold. The height of the liquid in the expansion tank should be between the markings. When the hot car is heated, the height of the liquid surface should be slightly higher than that of the superscript 4. Check the brake fluid and the level of the steering liquid to unscrew the bolts and directly observe whether the liquid level is within the specified marking range.
5, check the quality of oil No matter what kind of oil, can use the following methods to check. 1 1 l Appearance method to view the oil sample taken out, if more transparent, it indicates that the pollution is not serious; if it is in the form of fog, then there is water in the oil; if present, it may be contaminated by lead or other abrasives; if it is black, The high-temperature exhaust gas is 121. The oil sample taken will be dropped on the filter paper. If the diffusion is wide and there is no obvious difference between the oil droplet area and the diffusion area, the cleanness of the oil is good; otherwise, the oil is good. The liquid cleanliness becomes worse.
IV. Supplement 1. If there is no noticeable deterioration of the oil during the inspection of the oil, it shall be checked whether there is any leakage, if any, shall be excluded, and the same level of oil shall be filled in time.
2. Change of oil If the oil deteriorates or exceeds the replacement cycle, it should be replaced in time.
Usually every 8000km or half a year to change the oil once; every 20,000 to 40,000 kilometers or to replace the brake fluid in ~ 2 years; use 1-2 years to replace the cooling liquid; every use of one year or travel thousands of kilometers to replace once Hydraulic oil.
Everyone needs to learn how to maintain their own cars in daily life so that their cars can maintain good performance for a long time.
