Will Car Rust Remover Damage the Paint?

Car rust remover can cause some damage to the paint because car paint is primarily composed of resin, an organic compound that is relatively fragile. Many substances in the natural environment can harm the paint. Additionally, car paint naturally oxidizes when exposed to the air, and everyday driving encounters such as water stains, bird droppings, acid rain, and tree sap can also erode the paint surface. If not cleaned promptly, these can reduce the decorative and protective qualities of the paint. Function of Rust Remover: Rust remover plays a key role in enhancing and removing rust from fasteners, lubricating fasteners that cannot be disassembled, and facilitating the removal of rusted fasteners. It can treat and modify exposed metal surfaces, forming a long-lasting anti-corrosion barrier to prevent new rust. Rust remover is also an ideal lubricant and antifreeze, meeting the objective requirements for threading on stainless steel and aluminum surfaces. It can also effectively clean and dry electronic equipment, improving conductivity. Precautions for Using Rust Remover: Before using rust remover, shake the bottle vigorously to mix the contents evenly. Then, aim the nozzle at the rusted area that needs treatment. Wait for about one minute. If possible, soaking the rusted part yields better results. After the soaking duration is complete, use a wire brush to remove the rust. After rust removal, rinse off any residue with plenty of water. If rust prevention is needed after removal, thoroughly rinse with water, then neutralize and passivate with a 5% sodium hydroxide solution. After drying, spray a rust inhibitor for protection.

What to Do When the Car Air Conditioning Compressor Makes Noise When Starting?

Common causes of compressor noise are issues with the compressor's electromagnetic clutch. Since the compressor often operates under high load, the electromagnetic clutch has high requirements. Below are the specific reasons: 1. The compressor's electromagnetic clutch is a common source of noise: The compressor frequently operates under high load, shifting from low to high speeds, which places high demands on the electromagnetic clutch. Additionally, the electromagnetic clutch is usually installed close to the ground, often exposed to rain and dirt. When the bearings inside the electromagnetic clutch are damaged, noise occurs. 2. The tension of the compressor's drive belt also directly affects the lifespan of the electromagnetic clutch: If the drive belt is too loose, the electromagnetic clutch is prone to slipping; if the drive belt is too tight, the load on the electromagnetic clutch increases. Improper drive belt tension can lead to the compressor not working properly or even cause damage. When the drive belt is operating, if the compressor pulley and the generator pulley are not aligned in the same plane, it can reduce the lifespan of the drive belt or the compressor. 3. Repeated engagement of the electromagnetic clutch can also cause compressor noise: For example, insufficient generator output, excessive pressure in the air conditioning system, or excessive engine load can all lead to repeated engagement of the electromagnetic clutch. 4. The gap between the electromagnetic clutch and the compressor mounting surface: There should be a certain gap between the electromagnetic clutch and the compressor mounting surface. If the gap is too large, the impact increases; if the gap is too small, movement interference occurs between the electromagnetic clutch and the compressor mounting surface during operation, which is another common cause of noise.

Where is the rearview mirror heating button on the Leiling?

The rearview mirror heating switch on the Leiling is located in the air conditioning area below the central control screen. The switch is an icon marked with wavy lines enclosed in a square frame, which also serves as the switch for the rear windshield heating. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for the driver to frequently wipe the mirror manually, thereby reducing driving hazards. Methods to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is required, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees. The heat is then distributed across the left and right rearview mirrors. Meanwhile, due to the temperature increase and evaporation, water droplets on the mirror surface become smaller, and fog gradually dissipates, effectively heating the mirror and removing frost. However, if the rainfall is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the mirror. These wires consume a significant amount of power. Therefore, when using the rearview mirror heating function, ensure the car is in an ignited state. Avoid activating the function while the car is stationary to prevent draining the battery, which could hinder the car's ability to start. Other methods to defog rearview mirrors include: Opening windows for air circulation: Slightly opening the side windows creates airflow between the interior and exterior, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting can also help defog the mirrors by blowing warm air.

What to Do When a Car's Drainage Hole is Clogged?

Here are the specific situations: 1. Sunroof Drainage Hole: If the sunroof drainage hole is clogged, it can easily cause water to accumulate and flow along the roof to the sunroof motor inside the car. Once powered on, the sunroof motor may short-circuit or even burn out. The initial clogging of the sunroof drainage hole usually occurs at the entrance, which can be seen by opening the sunroof. At this stage, it is relatively easy to clean and can be done by yourself. 2. Engine Compartment Drainage Hole: Since the engine compartment is very close to the air conditioning intake, bacteria can easily grow in the stuffy compartment and affect the air quality inside the car through the air filter. In severe cases, water may flow into the car through the air conditioning intake, causing floor water accumulation. To unclog the engine compartment drainage hole, the upper cover plate needs to be removed for inspection. 3. Door Drainage Hole: Due to the low position of the door drainage hole, vehicles that frequently drive on muddy roads may have their drainage holes blocked by mud. Once the door drainage hole is clogged, water trapped inside the door panel can damage the window regulator, audio system, and central door lock. To clean the door drainage hole, a hard object like an iron wire can be used to unclog it. 4. Fuel Tank Cap Drainage Hole: Since the vehicle is used outdoors, sand and dust can accumulate around the fuel tank cap through the gaps. If this drainage hole is clogged, water may enter the fuel tank during car washing or rainy weather, causing damage to the fuel tank. To clean the fuel tank cap drainage hole, a high-pressure air gun or a hard object like an iron wire can be used. 5. Air Conditioning Drainage Hole: During the cooling process of the car's air conditioning, condensation water is produced, and the condensation water pipe is located under the chassis. During the rainy season, mud and water accumulation can also clog the drainage hole. The consequences are similar to those of the engine compartment drainage hole clogging, where water may flow back into the car, causing floor water accumulation. To clean the air conditioning drainage hole, a thin iron wire can be used to unclog it. 6. Trunk Drainage Hole: The spare tire area in the trunk is one of the lowest positions in the car body. If the vehicle wades through high water or water seeps in through the gaps in the headlights, water will flow to this position inside the car body. Since the drainage hole is rarely used and there is a high chance of rainwater flowing back into the car, most manufacturers seal the drainage hole. It can be unscrewed for cleaning or use when needed.
