Long-term parking vehicle maintenance Five-step routine inspection is indispensable

Vehicles that have been parked for a long period of time will gradually deteriorate the technical status of each assembly and mechanism due to atmospheric erosion, so that the original technical performance will be lost. In order to mitigate this adverse effect, the owner should often carry out the necessary maintenance work on the stopped vehicle to make it in good performance.

1. Always check the working condition of the engine

Start the engine at least once a month, run at idle speed for 4-5min, and check the operation of the engine. If there is any abnormal phenomenon, it needs to be adjusted and repaired in time.

2. Check the metal rust

Corrosion is mainly caused by the combined action of moisture, oxygen and corrosive substances in the air. Therefore, for cars that have been parked for a long time, the metal surface should be kept clean. The garage where the vehicle is parked should be kept regularly ventilated to keep the relative humidity of the air below 70%. The dust, dirt and moisture on the car need to be removed in time. The parts prone to corrosion and the surface of the machine parts should be coated with engine oil, grease or wrapped with oil paper. The pores on each assembly mechanism should be sealed to prevent air, moisture and dust from entering the interior.

3. Check the mildew of cotton and linen products and carpet, etc.

It easily absorbs water. Especially in wet areas and rainy seasons, it is more susceptible to moisture and mildew. Therefore, the owner should check the cotton and linen products on the vehicle frequently, dry them in time, and keep them dry.

4. Check that the antiknock performance of gasoline is reduced

The antiknock performance of gasoline depends on the level of gasoline octane. If the car is stopped for a long time, the octane number of gasoline will decrease with the loss of light components and the increase of gum content, which will reduce its anti-knock resistance. Therefore, the gasoline tank must be tightly closed, and avoid excessive temperature. It is best not to store gasoline for too long.

5. Check the aging and deterioration of rubber products

Rubber products on automobiles, such as tires, transmission belts, and dust covers, often suffer from aging, swelling, or deformation, resulting in deteriorated performance and shorter service life.

The aging of rubber products is mainly due to the fact that rubber belongs to unsaturated polymer hydrocarbons, which easily absorbs oxygen in the air and oxidizes. At the same time, vulcanized rubber also has a certain permeability, and oxygen easily enters the inside to play an oxidation role. Especially direct sunlight (Gallery Forum) can promote the rapid aging of rubber. When rubber products are contaminated with gasoline and engine oil, they will cause volume expansion, loose gums and reduced elasticity. To prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.
