How can a car be said to have vitality? For every car owner, the definition is naturally different. Driving is an important factor related to their "health", while maintenance is another important factor. If you know how to drive your car well, you should also know how to maintain it. Just like people's daily fermentation and beauty, you can take care of it carefully, so that your car can last for a long time.

1. Adverse reaction: a pool of inexplicable liquid dripped from under the car

Cause of condition: Generally speaking, the cause of the drip is a crack in the rubber tube connecting the coolant tank and the engine.

Maintenance: the deterioration of the quality of the coolant antirust, not only easy to cause damage to the radiator, pipes, hoses and other components, but also because the main component of the coolant is ethylene glycol, dripping to the ground will also cause environmental and air pollution. However, it is difficult to judge whether the coolant is deteriorated by visual inspection, so we should replace the coolant regularly, and never wait for the failure to repair. It is generally recommended that the vehicle should be replaced with a new coolant every 40000 km or two years, and the cooling fan belt should be replaced every two years.

2. Adverse reaction: the engine does not ignite

Cause of disease: starting system failure is probably caused by battery rust or battery leakage. Because the starting of the engine depends on the current of the battery to push the spark plug to ignite.

Maintenance: check whether the battery liquid in the battery is sufficient every one or two months. If not, add distilled water to the appropriate height. At present, most cars use maintenance free batteries, so it is not allowed to add water without authorization. In addition, check whether the positive and negative terminals of the battery are rusty or dirty every year. If so, go to the 4S shop to clean up in time to keep the circuit unblocked. After the battery is repaired, the scrapping time of the battery can be delayed, and the waste of resources and the pollution of the waste battery to the environment can be reduced.

3. Adverse reaction: the noise of engine exhaust is large, and the exhaust gas emission is large

Cause of illness: the exhaust gas of the engine is oxidized by high temperature, which may lead to the leakage of exhaust system.

Green maintenance: check whether the pipeline and interface of exhaust system are corroded by waste gas, and whether the interface pad is damaged. If the exhaust system leaks, repair or replace the leaking parts in time. Inspection once a year can not only ensure the normal operation of the exhaust system, but also reduce the environmental pollution caused by harmful substances in the exhaust gas.

4. Adverse reactions: increased fuel consumption

Cause of illness: there are many reasons for the increase of fuel consumption. But the most common and easily overlooked is the inspection of tire pressure. Insufficient tire pressure will not only increase driving resistance and fuel consumption, but also affect the service life of tires.

Green maintenance: self provided tire pressure gauge, check tire pressure frequently. Don't forget to check the spare tire, so as not to find that the spare tire is out of gas when it is necessary to replace the tire. When the temperature is high, the tire pressure will be higher than usual, so it is more accurate to measure the tire pressure in cold days or shady places. Every 10 000 km, the tires should be replaced to avoid the big difference between the front and rear wear. If it is necessary to replace the seriously worn tires, it is better to replace two or four tires together, and the tires with the same grain pattern can be replaced crosswise. In addition, the broken line pattern of the tire helps to save fuel.
