Should Car Modifications Be Done Before or After License Plate Registration?

First register the license plate, then proceed with modifications. Detailed Explanation: Currently, China's policies on car modifications are relatively restrictive. For example, the government allows modifications such as "gasoline to natural gas conversion" and "interior replacements," but major modifications in other areas are not permitted. This leads to issues with license plate registration for modifications in non-approved areas. If unapproved modifications are performed, the vehicle will not be eligible for license plate registration or annual inspections. Additional Information: Regarding annual inspections for modified vehicles after registration, when the periodic inspection comes up, the car can be handed over to a "vehicle inspection agent." If the owner insists on handling the inspection personally, the vehicle must be restored to its original condition before passing. Additionally, cars require regular annual inspections.

During my years as a car owner, I've always adhered to the principle of registering the vehicle before making any modifications. I remember a few years ago when I bought a new car, I couldn't resist the temptation and modified the exhaust system before completing the license plate registration. As a result, the vehicle was rejected at the DMV, forcing me to revert it back to the factory settings—wasting both money and time. A vehicle must meet factory standards to pass registration inspection; otherwise, modifications like spoilers, chassis alterations, or engine changes will be deemed illegal. Only after registration can you freely make minor modifications such as applying wraps, changing lights, or upgrading rims. However, ensure you file major modifications with the DMV to avoid issues during annual inspections. Those with ample budgets can consult professional shops to avoid repeating mistakes, as road safety should always come first.

Modified cars are truly exciting, especially for us young enthusiasts who often can't wait to make changes. For example, my friend who recently picked up his car immediately installed a body kit, only to get a ticket as soon as he hit the road. Remember, you must first register the car before making any modifications, because only the factory condition can pass the license inspection. Otherwise, if caught by traffic police, the consequences can range from a warning to having the vehicle impounded. Once the car is properly registered, it's okay to make minor changes that don't affect core performance, like seat covers or audio systems. However, modifications like turbocharging the engine or altering the exhaust system require additional registration to comply with regulations. When modifying your car, understanding local laws can help minimize risks.

After all these years in auto repair, I always advise my clients: 'License first, modify later' is the golden rule. A new car must be in its original factory condition to pass license inspection before hitting the road—any modifications to circuits or suspension will get rejected. A common mistake is failing the inspection after brake upgrades, forcing a revert to stock. Post-licensing modifications like lighting or wraps must meet safety standards; certified shops are your best bet to avoid annual inspection hassles or fines.

What type of engine oil does the Lynk & Co 01 use?

Lynk & Co 01 uses Shell SN-grade engine oil with the specification 0W-20. If you want to change the engine oil during later maintenance, you can choose fully synthetic Mobil 1 Gold or Castrol Edge. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Lynk & Co 01 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out. Use a specialized wrench to remove the oil filter. Apply a thin layer of oil to the seal of the new oil filter and tighten it clockwise by hand. Pour the new engine oil into the oil filler cap on the engine valve cover, typically filling about three-quarters of the bottle. Start the engine and let it run for 5 minutes, checking for leaks around the drain plug and oil filter. If leaks are found, repairs should be made. After stopping the engine, pull out the dipstick to check that the oil level is within the standard range.

What are the reasons why the Nissan X-Trail air conditioner is not cooling?

Reasons why the Chery car air conditioner is not cooling include insufficient refrigerant, severely clogged air filter, excessive debris on the surface of the evaporator, dirty condenser, refrigerant leakage, compressor damage, etc. Solution: Go to a repair shop to check whether the high and low pressure pipelines of the air conditioner are normal, whether the refrigerant is sufficient, whether the air filter is clogged, the working status of the compressor, etc., to troubleshoot the problem. Maintenance methods for car air conditioners: Comprehensive inspection of the air conditioner: When using the air conditioner for the first time in summer, first inspect the air conditioning system, such as checking the refrigerant and whether the air filter is too dirty through the liquid storage tank, whether there are foreign objects in the radiator, etc. Do not turn off the air conditioner immediately after parking: After arriving at the destination, car owners usually turn off the air conditioner and leave the car directly. Unlike in autumn and winter, the huge temperature difference between the inside and outside of the car in hot summer can cause the air conditioning system to become moldy, leading to the growth of mold. Therefore, car owners should turn off the cold air a few minutes before reaching the destination, turn on the natural wind, allow the temperature in the air conditioning pipes to rise, eliminate the temperature difference with the outside, thereby maintaining the relative dryness of the air conditioning system and avoiding mold reproduction.
