Maintain your car regularly to prevent diseases in the Big Four

1. Adverse reactions: The car leaked out of a pool of inexplicable liquid

Cause of illness: In general, the cause of a leak is a crack in the rubber hose connecting the coolant tank to the engine.

Maintenance: Deterioration of the anti-rust quality of the deteriorated coolant not only leads to the damage of radiators, pipes, hoses, etc., but also causes the environment and air pollution because the main component of the coolant is ethylene glycol. However, it is difficult for us to visually judge whether the coolant is deteriorating. Therefore, it is necessary to replace the coolant regularly, and do not wait until the fault occurs before repairing. It is generally recommended that the vehicle should be replaced with new coolant every 40,000 kilometers or two years. In addition, the cooling fan belt must be replaced every two years.

2. Adverse reactions: The engine is not on fire

Cause of illness: Failure to start the system is most likely due to battery rust or battery leakage. Because the start of the engine is driven by the electric current of the battery to push the ignition of the spark plug.

Maintenance: Every two months to see if the battery liquid in the battery is sufficient. If not enough, add distilled water to the appropriate height. At present, most cars use maintenance-free batteries, they must not add water. In addition, check the battery terminals for signs of rust or dirt every year. If so, it is necessary to clear the 4S shop in time to keep the circuit open. After the battery is repaired, it can delay the battery's scrap time, reduce the waste of resources and the pollution of the waste battery to the environment.

3. Adverse reactions: Engine exhaust noise, large exhaust emissions

Cause of illness: Oxidation of the engine's exhaust gas occurs at high temperatures, which may cause leakage of the exhaust system.

Green maintenance: Check whether the pipeline and interface of the exhaust system are corroded by exhaust gas and whether the interface pad is damaged. If leaks in the exhaust system are discovered, leaks should be promptly repaired or replaced. Checking once a year will not only ensure the normal operation of the exhaust system, but more importantly, reduce the pollution of harmful substances in the exhaust gas to the environment.

4. Adverse reactions: Increased vehicle fuel consumption

Cause of illness: There are many reasons for the increase in fuel consumption. But the most common and easy to ignore by us is the inspection of tire pressure. Insufficient tire pressure not only leads to increased running resistance, resulting in increased fuel consumption, but also affects the service life of the tire.

Green maintenance: bring your own tire pressure gauge and always check the tire pressure. Do not forget to check the spare tire, so as to avoid urgent need to replace the tire, only to find that the spare tire has no gas. When the temperature is high, the tire pressure will be higher than usual, so it is more accurate to measure the tire pressure in a cold or cool place. From time to time, every 10,000 km of tires must be interchanged, avoiding too much difference in front and rear wear. If it is necessary to replace tires that are heavily worn, it is best to replace them with two or four, and tires with the same pattern can be interchanged before and after. In addition, lined tires help save fuel.
