Will 4S shops perform internal rust prevention after sheet metal repair?

4S shops will perform internal rust prevention after sheet metal repair. Automotive sheet metal is a technical means of car repair, referring to the restoration of the vehicle body after a collision, which includes all work except for the anti-corrosion and decorative painting of the body. After the sheet metal shaping is completed, because the underlying metal is exposed, it is necessary to apply anti-rust primer. Below are some tips for car rust prevention: 1. Regularly check the humidity in areas prone to water accumulation: It is inevitable for vehicles to encounter rainy or snowy weather or pass through muddy and waterlogged roads during travel. Areas such as the bottom of the body and gaps inside the car can easily accumulate sludge. If the owner does not clean it in time, moisture can hide. Therefore, areas like the inner and outer edges of the wheel hubs, doors, bottom corners of the trunk, keyholes, and moving parts of the wiper arms should be checked frequently. At the same time, ensure that the drainage holes of the doors and various parts of the body are clear, and check the humidity of interior coverings, such as carpets, to prevent rusting of floor components. 2. Apply glaze to soft paint surfaces: For vehicles with softer paint surfaces, sand particles hitting the body during high-speed driving can cause fine scratches. For such cars, applying glaze to the body can form a strong protective mesh film, increasing the hardness of the paint surface, with effects lasting about a year. Coating can also achieve similar results. Additionally, applying undercoating or sealing to the vehicle's underside can protect the chassis from acid rain and corrosion, preventing the original protective layer from cracking or peeling off, and also shielding against small stones hitting the chassis during driving. 3. Avoid using car covers: If a vehicle is parked outdoors and encounters windy or rainy weather, the inner layer of the car cover will repeatedly whip the paint, especially if sand gets blown inside the cover, causing countless fine scratches on the body. Over time, this can dull the paint. Also, after a sandstorm, do not use a duster or cloth to clean the sand particles on the body directly; instead, rinse with water to prevent the sand particles on the duster or cloth from scratching the paint. 4. Handle minor rust spots yourself: For minor scratches or rust spots that have already appeared on the body, if the owner ignores them, they can easily rust, but it may not be worth spending money at a car beauty shop. In such cases, the owner can use some simple methods to handle them personally.

Why Does Car Antifreeze Decrease?

Antifreeze reduction is a normal phenomenon, including engine oil, windshield washer fluid, etc., which will decrease during the use of the car. The main reason for the decrease in antifreeze is natural evaporation. Antifreeze has a cooling effect on the car engine, and the car engine often operates at high temperatures. Since antifreeze comes into contact with the engine, some consumption is normal. Methods for selecting antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level scale on the antifreeze tank. Normally, antifreeze should be between the maximum and minimum water levels. Whether antifreeze is low depends on the scale. If the antifreeze is below the minimum water level, it indicates a shortage.

How long does a car battery generally last?

Car batteries typically have a lifespan of 2 to 4 years. Here are more details about car battery lifespan: 1. Regular car batteries use lead-acid technology with a cycle life of approximately 200 to 500 charges. 2. Vehicles equipped with auto start-stop systems use specialized batteries that offer higher cycle life (400-800 charges) and longer service life (4-6 years). 3. New energy vehicles use lithium batteries which have the longest lifespan, lasting 5 to 8 years. Extended information: Methods to prolong battery life include avoiding using in-car devices or external power sources when the engine is off; always turning off headlights when parking overnight; performing battery checks every six months; and disconnecting all in-car electronic devices from the battery when the vehicle won't be used for extended periods.

What are the differences between diesel and 92 gasoline?

Here are the differences between 92# gasoline and diesel: 1. Gasoline is highly volatile, while diesel is difficult to volatilize. Therefore, gasoline vehicle pollutants include fuel evaporation emissions, whose components are hydrocarbons. 2. Gasoline easily mixes with air and is hard to separate once mixed. Gasoline and air can mix very evenly, with basically no local over-concentration or over-dilution or liquid oil droplets. Gasoline molecules are smaller. Diesel and air mix unevenly, inevitably leading to local oxygen deficiency or local oxygen surplus. When fuel is in a high-temperature and oxygen-deficient environment, it tends to carbonize and form soot. Diesel combustion produces some odorous organic gases, so diesel engine emissions also have a smell. 3. The chemical difference between the two is that gasoline has fewer carbon atoms, 8-10, while diesel has 12-15, so diesel contains higher energy. Diesel does not need ignition and self-ignites under higher pressure, so its combustion efficiency is higher, but it is very heavy and noisy. Gasoline requires ignition, so gasoline engines are smaller in size and quieter. 4. The smell is different: gasoline has a pungent smell, while diesel has a mild smell. The color is different: gasoline is light-colored, while diesel is dark-colored. The concentration is different: gasoline is thinner, while diesel is thicker. The ignition method in vehicles is different: gasoline is ignited by spark plugs, while diesel is compression-ignited. Diesel has poor anti-knock properties, and diesel has less horsepower, heavier pollution, and emits black smoke compared to gasoline, but it is cheaper.

What is the appropriate temperature for car air conditioning?

It is best to keep the car interior temperature between 18-25 degrees Celsius. Generally, a temperature difference of within 10 degrees between the inside and outside of the car is appropriate. The most comfortable temperature for the human body is 20-25 degrees. If it exceeds 28 degrees, people will feel hot, and if it is below 14 degrees, people will feel cold. How to activate the air conditioning heating: In winter, if you need to use the car air conditioning, you should start the car first and wait a few minutes. The engine will begin to warm up. When the engine temperature gauge reaches the middle position, turn on the air conditioning heating. However, you should also set the air circulation mode to external circulation to expel the cold air from the car. After 5 minutes, you can switch back to internal circulation and start driving. When the car is just started, the engine coolant temperature has not yet risen. Turning on the air conditioning heating immediately will dissipate the already limited heat. Each car's engine has its optimal working state. If the temperature is too high or too low, it will not only damage the engine but also increase fuel consumption. How car air conditioning works: Car air conditioning does not have a heating function. The warm air in car air conditioning comes from the engine's heat dissipation. Therefore, those who need to use the heater in winter do not have to worry about additional fuel consumption like in summer when using the air conditioning for cooling. Just pay attention to the timing of turning on the heater. Also, please note that the term 'air conditioning heating' mentioned in this article actually refers to turning on the heater.
