Rehabilitation and re-cultivation – common causes and maintenance tips of the car

1. Adverse reactions: A leaky liquid leaks out of the car, and the liquid level of the coolant drops.

Cause: The usual cause of dripping is a crack in the rubber tube connecting the coolant tank to the engine.

Green Maintenance: Deteriorated coolant has reduced rust quality, which not only causes damage to radiators, pipes, hoses, etc., but also because the main component of the coolant is ethylene glycol, which leaks to the ground. It can cause environmental and air pollution. However, it is difficult to visually judge whether the coolant has deteriorated, so it is necessary to replace the coolant regularly, and wait until the fault occurs before replacing the coolant. It is generally recommended that the vehicle be replaced with a new coolant every 40,000 kilometers or two years, and that the cooling fan belt must be replaced every two years.

2, adverse reactions: the engine does not catch fire.

Cause: The start of the engine is based on the current of the battery to push the spark plug to complete the ignition, so the startup system fails, probably due to battery rust or battery dripping.

Green Maintenance: Check the battery liquid in the battery for every two months. If not enough, add distilled water to the appropriate height. At present, most cars use maintenance-free batteries, so you can’t add water without authorization. In addition, every year, check the positive and negative terminals of the battery for rust or dirt. If there is, please go to the 4S shop to clean up in time to keep the circuit open. After the battery is repaired, it can delay the scrapping time of the battery, reduce the waste of resources and the environmental pollution of the discarded battery.

3, adverse reactions: engine exhaust noise increased, exhaust emissions also exceeded the standard.

Cause: The exhaust gas of the engine is oxidized by high temperature, which may cause leakage of the exhaust system.

Green maintenance: Check whether the exhaust system piping, interface (especially silencer, etc.) are corroded by exhaust gas, and the interface pad is not damaged. If it is found that the exhaust system leaks, repair or replace the leaked parts in time. Checking once a year not only ensures the normal operation of the exhaust system, but more importantly reduces the environmental pollution of harmful substances in the exhaust gas.

4, adverse reactions: car fuel consumption continues to increase.

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

Green Maintenance: Bring your own tire pressure gauge and check the tire pressure frequently. Don’t forget to check the spare tires, so that you don’t need to change tires, you will find that the spare tires are out of 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 cold weather or in the cool place. At times, the tires are interchanged every 10,000 kilometers, avoiding the difference in front and rear wear. If it is necessary to replace the tires with severe wear, it is best to change 2 or 4 together, and the tires with the same texture can be replaced before and after. In addition, the polygonal tires help save fuel.
