Maintenance tips for idle car batteries, commercial vehicles need to prevent rust and aging after mo

1. Prevent metal rust

Rust is mainly caused by the combined action of water, oxygen and corrosive substances in the air. Therefore, for vehicles parked for a long time, the metal surface should be kept clean. The garage where the vehicle is parked should always be ventilated and the relative humidity of the air should be kept below 70. Dust, dirt and moisture on the vehicle should be removed in time. The surfaces of parts and machine parts that are prone to rust should be oiled, greased or wrapped with oil paper. The pores on each assembly mechanism should be sealed to prevent air, moisture and dust from entering the interior.

2. Prevent rubber products from aging and deterioration

Rubber products on automobiles, such as tires, drive belts, dust covers, etc., often age, expand or form, resulting in poor performance and short service life. The aging of rubber products is mainly due to the fact that rubber is an unsaturated polymer hydrocarbon, which is easily oxidized by absorbing oxygen in the air. At the same time, vulcanized rubber has a certain permeability, and oxygen can easily enter the interior for oxidation. In particular, direct sunlight can promote the rapid aging of rubber. When rubber products are contaminated by gasoline and engine oil, their volume will expand, the glue will become loose, and the elasticity will decrease. To prevent rubber products from aging, they should be kept away from direct sunlight and contact with mineral oil.

3. Prevent cotton and linen products from getting moldy

Mat and carpet easily absorb moisture. Especially in humid areas and rainy seasons, they are more susceptible to moisture and mold. Therefore, car owners should regularly check the cotton and linen products in the car, dry them in time, and keep them dry.

4. Prevent gasoline from deteriorating in anti-knock performance

The anti-knock performance of gasoline depends on its octane number. When the vehicle is parked for a long time, the octane number of gasoline will decrease with the loss of light components and the increase of glue content, thereby reducing its anti-knock performance. Therefore, the fuel tank should be sealed to avoid excessive temperature. The storage time of gasoline should not be too long.

5. Check the working status of the engine frequently

Start the engine at least once a month, idle for 4-5 minutes, and check the engine operation. If there is any abnormality, it needs to be adjusted and repaired in time. In addition, check the battery frequently. The battery electrolyte height should be 10mm ~ 15mm higher than the electrode plate. If it is insufficient, you should add distilled water in time and charge the battery if necessary.
It is recommended not to park your car for a long time. If you don't drive it on weekdays, you can drive it out for a stroll on the weekend, which is also very good.
