How to maintain and maintain the car?

Car maintenance (maintenance) 1: Daily car maintenance.

The daily maintenance of the car is carried out by the driver before driving, during driving and after receiving the car. Before leaving the car, look around the car to see whether the lighting device is damaged, whether the car body is tilted, whether there is oil leakage, water leakage and other leakage phenomena, check the appearance of tires, and check the conditions of doors, hoods, trunk lids, glass and so on.

Turn on the ignition key, check the lighting of all warning lights and indicator lights, start the engine, and check whether all warning lights are normally extinguished; See if the indicator light is on normally; Check the indication of fuel gauge and replenish fuel if necessary.

Car maintenance (maintenance) II: Weekly car maintenance.

Find out the fixing of engine accessories and check whether the engine joint surface leaks oil or water; Check and adjust the tightness of the belt, check the fixing of pipelines and wires in all parts, and check the oil supply; Check the supplementary coolant; Check the supplementary electrolyte and power steering oil; Clean the radiator surface; Replenish windshield cleaning fluid, etc. Clean the appearance of the car; Clean all parts of the car.

Car maintenance (maintenance) III: Monthly car maintenance.

In the monthly car maintenance, the weekly car maintenance items should be repeated, but the inspection work should be more detailed. Patrol the car, check the damage of light bulbs and lampshades, and check the fixing of body accessories; Check the fixation of the mirror; Check the tire wear, and replace the tire when there are wear marks near the tire.

Check whether the tire is bulging, abnormal wear, aging and hard injury; Thoroughly clean the car, clean up the excess items in the luggage compartment, and don't let the car become a mobile warehouse; Clean the sundries on the surface of water tank, oil radiator and air conditioner radiator; Clean the appearance of the car, remove oil stains from the car body and repair the painted parts.

Car maintenance (maintenance) IV: Maintenance once every six months.

Semi-annual car maintenance is generally arranged in spring and autumn.

Clean the engine surface, pay attention to the waterproof treatment of electrical parts when cleaning, avoid washing the engine with high pressure and high temperature water gun, and clean the engine surface with a brush dipped in cleaning agent.

Clean or replace the "three filters" and engine oil, blow off the dust on the air filter with compressed air, replace the fuel filter and increase the filter screen of the pipeline joint as appropriate. When replacing the engine oil filter, the engine oil should be replaced. Check whether the battery terminals are corroded, wash the battery surface with hot water, remove the corrosion on the battery terminals, and measure and adjust the electrolyte density of the battery.

Check the supplementary coolant, clean the appearance of the water tank, check the wheel fat wear, and change the tires. Check the pre-tightening condition of the hub bearing, and adjust the brake shoe of the central drummer if there is any gap; Check and adjust the free travel of the pedal; Check the wear of wheel brake shoes. If the wear mark is reached, replace the brake shoe, check and adjust the shoe clearance of the wheel brake, and check the supplementary brake fluid.

Check the tightness of important bolts or nuts of chassis, especially those of steering system. If it is found to be loose or defective, it should be tightened again.

Check whether there is any leakage in the pipelines of various parts of the chassis, check the fastening of all metal connecting rods, and check whether the rubber shaft sleeve is damaged; Lubricate all lubricating points of the chassis with grease. Thoroughly clean the inside and outside of the car and repair the paint and damaged parts. Inspection and maintenance of car lights, inspection and maintenance of refrigeration and heating devices; Clean sound system, etc.

Brief introduction to the specific process of automobile maintenance

The first thing is to check the fuel quantity of the engine. When driving on an airplane, it is normal if the fuel quantity is within the marked range of (f) and (l). If it is lower than (L), the specified engine oil should be added, and the refueling level should not be higher than (F).

The second is the maintenance inspection of the battery, mainly to check whether the battery is firm. When the electrolyte approaches the lower line between the upper line and the lower line, pay close attention to replenish the electrolyte to ensure good contact between the positive and negative cables of the battery and keep the battery clean and dry.

The third is the inspection of the air filter. Stolen air filters can lead to poor engine operation, excessive oil consumption, engine damage and so on. When checking the air filter, if there is less dust and light blockage, you can use high-pressure air to blow it clean from the inside out and continue to use it. The stolen air filter should be replaced in time.

The fourth is the inspection of spark plugs. Spark plug normal insulation ceramics intact, no leakage phenomenon. When the spark plug gap is 0.8+-0.0mm, the spark is blue and intense. If out of phase is found, adjust the gap or replace the spark plug.

Fifth, check the gasoline filter. If poor oil supply is found, check whether the gasoline filter is blocked. If it is blocked by foreign objects, it needs to be replaced.

The sixth is the inspection of tires. Tire pressure should be checked at room temperature every month. Below the normal standard, it should be supplemented in time. The air pressure should not be too high or too low, otherwise it will affect the driving safety. If the tire has cracks, it should be replaced in time. When choosing tires, we should pay attention to the consistency of models.

The seventh is to check the refrigeration liquid level, which indicates normal between high and low braking positions. If it is lower than the off-line position, it may leak air or the brake shoes are worn, so it is necessary to go to the maintenance station for repair. When adding brake fluid, pay attention to adding the same type of brake fluid to prevent the cup from being worn, and pay attention to protecting the paint surface to prevent the paint surface from being corroded.

The eighth is the inspection of the clutch master pump page. If the clutch liquid level is between the high and low pages, it is normal. If it is lower than the standard line, it may be that the master cylinder or slave cylinder cup is damaged, and it is difficult to shift gears when the engine is running, or it is impossible to shift gears. Please repair it.

The ninth is to check the engine coolant level. When the engine is at a high temperature, do not open the radiator cover, otherwise it may be scalded by the overflowing high-temperature coolant. After the engine is cooled, check whether the engine coolant level is between full and low level, otherwise distilled water or pure water (mineral water is not allowed) or coolant should be added.

The added liquid should not exceed the full level. If the coolant decreases rapidly in a short time, check whether there is any leakage in the cooling system.

The tenth is the inspection of belt. Abnormal belt sound during normal start-up or driving. One is because it has not been checked and adjusted for a long time, and it is expected to be adjusted according to normal standards. The other is that the belt is aging and needs to be replaced.
