How to maintain the car

There are two main aspects to vehicle maintenance. One is the mandatory maintenance provided by the repair station. On the other hand, some daily maintenance is done by the owner. The normal maintenance of the vehicle is related to the service life of the vehicle and the safety of the driver and passengers. Improper maintenance or use will cause vehicle failures and bring safety hazards. So what are the maintenance items for the car as a family sedan? Today we will talk about car maintenance items and daily car maintenance knowledge.

★Check engine oil

Park the vehicle on a level road. Pull out the vernier to check the oil level. If the oil is within the two marking lines (F) and (L), it belongs to the normal range, and if it is lower than the (L) position. The specified type of engine oil should be added, and the liquid level after refueling cannot be higher than (F) level.

★Engine coolant level inspection

Never open the radiator cover when the engine is in a warm state, otherwise you may be scalded by the spilled coolant or high-temperature steam.After the engine is cooled, check that the liquid level of the coolant should be between the full level and the low level. Otherwise, distilled water or purified water (mineral water can not be added) or refrigerant should be added. The height of the liquid level after adding water should not exceed the full level. If it is found that the cooling fluid decreases rapidly in a short period of time, check the cooling system for leaks or go to the maintenance station for inspection.

★Check the brake fluid level

If the brake is also between the high and low positions, it means normal. If the brake fluid is close to the lower limit or lower than the lower limit, it means that there may be a leak in the system or the brake shoes are worn too much, and you should go to the repair station for inspection and repair in time.

When refilling brake fluid, pay attention to adding the same type of brake fluid to prevent damage to the cup, and pay attention to protect the paint to prevent corrosion of the paint surface.

★Check the liquid level of the clutch master cylinder

If the fluid level of the clutch is between the high and low fluid levels, it means it is normal. If it is lower than the standard line, the master cylinder or the sub-cylinder cup may be damaged. When the engine is running, it will be difficult or impossible to shift gears. Please go to the nearest maintenance station for inspection and repair immediately.

★Maintenance and inspection of battery

Check whether the battery is firmly fixed, the electrolyte should be between the upper limit and the lower limit, and the electrolyte or distilled water should be added to the upper line in time when it is close to the offline.Keep the positive and negative cables of the battery in good contact, and keep the battery clean and dry. For vehicles that have been stored for a long time, remove the positive and negative cables of the battery, and re-wire the battery after about half a month. After starting the engine for about 20 minutes, charge it in time if the battery is obviously insufficient.

★Inspection of tires

The tire pressure should be checked at room temperature every month. If it is lower than the normal standard, the tire pressure should be refilled in time.The air pressure cannot be too high or too low, otherwise it will affect the safety of driving.

Check the tires for cracks, and replace the tires in time when there are potential safety hazards.

When choosing tires, make them the same model.

★Inspection of belt

When starting the engine or driving the vehicle in normal times, the belt hums. One situation is that the belt has not been checked and adjusted for a long time, and it can be adjusted according to normal standards. Another situation is that the belt is aging and needs to be replaced.

★Inspection of air filter

If the air filter is too dirty, it will cause poor engine operation, excessive fuel consumption, and damage to the engine. When checking the air filter, if there is less dust and lighter blockage, you can use high-pressure air to blow it from the inside out and continue using it.The dirty air filter should be replaced in time.

★Spark plug inspection

Normal spark plug insulation ceramics are intact.There is no rupture and leakage phenomenon. When the spark plug gap is 0.8+-0.0mm, the spark is blue and strong.If an abnormality is found, the gap should be adjusted or the spark plug should be replaced.

★Check the gasoline filter

If you find that the fuel supply is not smooth, check whether the gasoline filter is clogged, and replace it in time if the foreign matter is clogged.
