Is it necessary to deal with scratches on car light covers?

It is necessary to deal with scratches on car light covers. If there are many scratches on the car light cover, it will affect the brightness of the lights during night driving, and in severe cases, it may even cause traffic accidents. Therefore, it is necessary to deal with scratches on car light covers. Repairing scratches on car lights requires professional technicians at professional beauty shops to use specialized products. Generally, polishing and restoration procedures are used to repair the scratches, aiming to restore a smooth and flat effect as much as possible. However, severe physical damage cannot be successfully repaired through beauty treatments. It is necessary to assess the damage before deciding whether to sand it. Methods for dealing with scratches on car light covers: Toothpaste polishing: If there are fine scratches on the car headlights that do not affect normal use, toothpaste can be used for polishing because toothpaste contains abrasive particles, which can help with minor scratches. Polishing repair: For longer scratches and cracks on car headlights, fine sandpaper can be used for sanding, followed by polishing with polishing wax, similar to the principle of paint polishing. Replace the light cover: If the scratches on the car light cover are severe and already affect normal driving, it is necessary to go to a professional repair shop to replace the car light cover in time.

Is it okay to drive at 75 in a 70 speed limit zone?

Driving at 75 in a 70 speed limit zone is not okay. Reasons are as follows: Speeding: Exceeding the 70 speed limit to 75 constitutes speeding. Do not exceed the specified speed: When driving on the road, motor vehicles must not exceed the specified speed, and exceeding the specified speed constitutes speeding. According to the "Road Traffic Safety Law of the People's Republic of China" regulations: If the speed exceeds the specified speed limit by less than 10%: A warning will be given. For roads with a speed limit below 50 kilometers: If the speed exceeds the specified speed limit by 10% to less than 20%, a fine will be imposed; if it exceeds the specified speed limit by 20% to less than 50%, a fine will be imposed; if it exceeds the specified speed limit by 50% to less than 70%, a fine will be imposed; if it exceeds the specified speed limit by 70%, a fine will be imposed. For roads with a speed limit between 50 and 80 kilometers: If the speed exceeds the specified speed limit by 10% to less than 20%, a fine will be imposed; if it exceeds the specified speed limit by 20% to less than 50%, a fine will be imposed; if it exceeds the specified speed limit by 50% to less than 70%, a fine will be imposed; if it exceeds the specified speed limit by 70%, a fine will be imposed.

What is the difference between tire pressure display and tire pressure warning?

The difference between tire pressure display and tire pressure warning lies in their functions: The tire pressure display function visually shows the tire pressure on the car dashboard; The tire pressure warning is an alarm system that triggers alerts when the tire pressure is too high or too low. Methods to eliminate the tire pressure warning include: 1. After confirming normal tire pressure, inspect the tire pressure sensors and clear the fault code; 2. Locate the settings button on the central console for manual reset, then press the set button; 3. Check and ensure the tire pressure is normal, adjusting it to the standard pressure if necessary, at which point the system will automatically correct and reset.

Reasons for Low Intake Pressure

Reasons for low intake pressure may include blockages in the refrigerant system's liquid supply pipe, expansion valve, or filter, insufficient refrigerant charge in the system, excessively long evaporator pipelines, etc. Blockages: Blockages in the refrigerant system's liquid supply pipe, expansion valve, or filter, or insufficient opening, malfunctioning float valve, low ammonia liquid circulation in the system, insufficient height difference or small pipe diameter in the intermediate cooler's liquid supply, can all lead to excessively low compressor suction pressure. Insufficient Refrigerant Charge: Insufficient refrigerant charge or liquid supply in the system, or improper adjustment of the throttle valve, can result in low compressor suction pressure. Excessively Long Evaporator Pipelines: If the evaporator pipelines are too long or if the design of the parallel suction header for multiple compressors is improper, it can also cause low compressor suction pressure. Excessive Oil Content in Freon System: Excessive oil content in Freon systems, which easily dissolves oil, can lower the suction pressure. Thick Frost or Oil Buildup in Evaporator: Thick frost or oil buildup on the inner walls of the warehouse evaporator increases thermal resistance, leading to reduced suction pressure.

Does Scratching the Car Chassis Affect the Vehicle?

Scratching the car chassis can affect the vehicle's lifespan and also pose a threat to driving safety. Regular inspections are necessary. Generally, as long as the suspension system is not damaged to the point of deformation, there shouldn't be major issues. Common damages to the car chassis include: Undercarriage scraping and foreign object impacts: During road repairs, there are often large rocks or uneven surfaces. When driving on such roads, it's easy for large rocks or other protruding objects to come into close contact with the vehicle's chassis, commonly referred to as undercarriage scraping. Since undercarriage scraping is unpredictable, it can easily damage components located on the chassis, such as: cracking the catalytic converter shell, engine oil pan, or transmission housing, or deforming the suspension system. These issues can cause fatal damage to the vehicle. Corrosion: With the worsening environment, even rain has become acidic, increasing the likelihood of vehicle damage in such conditions. The chassis frequently comes into contact with sewage, grease, and other substances, whose chemical components can slowly corrode the chassis and its parts. Therefore, extra attention should be paid to chassis corrosion prevention. Besides the aforementioned risks from rainwater and oil sludge, snow-melting agents used in winter and seawater can also corrode the chassis, especially seawater.
