Check if the refrigerant is sufficient. You can estimate by feeling the temperature difference between the inlet and outlet pipes of the dryer, or use a manifold pressure gauge for detection. Relevant information is as follows: 1. Causes: High pressure may be due to clogging. It is recommended to check the expansion valve, evaporator, and whether the dryer bottle is installed backwards. This is a sign of insufficient refrigerant. Compressor issues. Poor-quality compressors, even new ones, can exhibit such problems. 2. Solutions: Regularly clean the air vents and dust and dirt in the cabin. This not only helps maintain the car's appearance but is also beneficial for the health of the driver and passengers.

Why is the brake light of Dongfeng Fengguang 580 always on?

If the brake light of Dongfeng Fengguang 580 remains constantly illuminated, it indicates a potential system malfunction. It is recommended to use an automotive diagnostic scanner at a repair shop, where technicians will perform corresponding repairs based on the fault codes. Below are relevant details: 1. Possible causes: During driving, the force applied to the brake pedal is transmitted through the master cylinder piston, which sends brake fluid to each wheel's brake cylinder. This action causes the brake pads to contact the wheels, thereby achieving braking. Insufficient brake fluid is often accompanied by noticeably reduced braking power, and in severe cases, complete loss of braking force may occur. Low brake fluid levels can cause the brake pedal to sink, keeping the brake switch continuously energized and resulting in constant illumination of the brake light. 2. Powertrain: The Fengguang 580 is equipped with two engine options: a 1.8L naturally aspirated engine and a 1.5L turbocharged engine. The 1.8L naturally aspirated engine delivers 139 horsepower with a maximum torque of 187 N·m, featuring multi-point fuel injection technology, and utilizes an aluminum cylinder head with cast iron cylinder block.

Can a car be wrapped to change its color?

It is possible to change a car's color by wrapping it, but it must be registered after the color change. According to Article 56 of the "Regulations on the Registration of Motor Vehicles," if the body color is changed without completing the required registration, the traffic management department of the public security authority may issue a warning or impose a fine. The vehicle may also be impounded and required to revert to its original color. To apply for a change in the body color of a motor vehicle, the following documents must be submitted in accordance with the "Road Traffic Safety Law": the "Application Form for Motor Vehicle Modification Registration," identification documents of the vehicle owner and agent, the motor vehicle registration certificate, and the motor vehicle license. According to Article 6 of Chapter 2 of the "Road Traffic Safety Law," if the color change covers no more than 30% of the vehicle's surface, no registration is required. However, if it exceeds 30%, the change must be recorded, and registration must be completed within 10 days after the color change. Precautions for changing a vehicle's color: Before changing the color of a motor vehicle, it is necessary to consult the local vehicle management office where the vehicle is registered to confirm whether the region permits color changes via wrapping. If the region does not allow this method, the modification cannot be registered, and the wrap must be removed to restore the vehicle's original color. Additionally, according to the "Regulations on the Registration of Motor Vehicles," owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle's color, install body kits, replace the engine, etc., and then apply for modification registration with the vehicle management office. According to Article 10, registered motor vehicles must apply for modification registration in the following cases: Change of body color. Replacement of the engine. Replacement of the body or frame. Whole vehicle replacement due to quality issues. Change of use, such as converting a commercial vehicle to a private vehicle or vice versa. Change of the vehicle owner's residence into or out of the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with designated patterns and equipped with alarms and signal lights as required. Other motor vehicles are prohibited from using similar patterns, alarms, or signal lights specific to these vehicles.

Can the ETC still be used after vehicle transfer?

The ETC cannot continue to be used after vehicle transfer. Because the vehicle information has changed, the ETC associated with the vehicle will become invalid. The original owner needs to cancel the previous ETC information, and the new owner needs to apply for a new ETC with the following documents: the new owner's ID card and its copy, the vehicle license and the last vehicle inspection record on it, and a debit card. The documents that the original owner needs to provide for a used car transfer include: the registration certificate, vehicle license, and ID card. The buyer needs to provide an ID card, and if they are from another city, they need a residence permit or temporary residence permit. For vehicle transfer, the first step is to conduct a vehicle evaluation. The evaluation fee is generally 1%-2% of the evaluated vehicle price, and other fees include the license plate, vehicle license, etc. The original vehicle's commercial insurance can be canceled (compulsory insurance cannot be canceled), or the insurance can be transferred to the buyer at the insurance company. Precautions for buying used cars: Incomplete procedures. The complete procedures for a used car include: vehicle registration certificate (or original purchase invoice), vehicle license, vehicle purchase tax payment certificate, road maintenance fee procedures, and compulsory insurance. If the vehicle registration certificate or vehicle license is missing, or if there are arrears in compulsory insurance or road maintenance fees, it will bring endless trouble to the buyer. Therefore, when buying a car, if the seller cannot provide complete procedures, consumers should be especially vigilant. Tampering with the odometer. Most consumers like to judge the condition of the car based on the odometer, and sellers often take advantage of this psychology to tamper with the odometer. In fact, the odometer is not only an indicator of usage intensity but also a recorder of the maintenance and replacement of other vehicle parts. If the buyer follows the maintenance schedule based on a tampered odometer, it will bring a series of potential safety hazards. New paint covering external injuries. When consumers choose a used car, if the car has been repainted and there are repair marks around the front face, rear, and A, B, and C pillars, the car is very likely to have been involved in a major accident. Adjusting the heart to raise the price. Many consumers often pay too much attention to the heart of the car (engine) when buying a car and ignore the health of the car body. Used car sellers take advantage of this psychology by replacing engine parts to make the heart of the car appear younger, thereby raising the price.

What is the Difference Between Replacement and Renewal of a Driver's License?

Replacement: When a driver's license is lost, a new one needs to be issued. Article 63 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": If a motor vehicle driver's license is lost, the motor vehicle driver shall apply for a replacement at the vehicle management office of the issuing authority or another vehicle management office outside the issuing authority. Renewal: The driver's license is not lost, but its validity period has expired, requiring a new license to be issued. Article 57 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": A motor vehicle driver shall apply for a renewal at the vehicle management office of the issuing authority or another vehicle management office outside the issuing authority within 90 days before the expiration of the motor vehicle driver's license. Renewal: When a driver's license is about to expire, it must be renewed with a new one, which can be done up to 90 days in advance. Plan your time wisely to prevent expiration. Before renewal, check for any traffic violation records. If there are any, they must be cleared before renewal. Fill out the renewal application form and submit the following documents and proofs: Identity proof of the motor vehicle driver. The motor vehicle driver's license. A medical condition certificate issued by a county-level or military medical institution at the regiment level or above. Submit all documents and materials to the staff, pay the fee, and receive the new driver's license. Replacement: Apply for a replacement promptly. Otherwise, driving without a license may result in fines if caught by traffic police. Fill out the replacement application form and submit the following documents and proofs: Identity proof of the motor vehicle driver. A written statement declaring the loss of the motor vehicle driver's license. Submit all documents and materials to the staff. The process is usually completed on the spot. The difference between a replaced license and the original one lies in the barcode (also known as the license core code) on the back of the main copy: After replacement, the original driver's license becomes invalid and must not be used. If the original driver's license is used after obtaining a replacement, the old license will be confiscated by the traffic management department of the public security authority, and a warning or fine may be imposed. Replacement is for when the driver's license is lost, and a new one is issued to replace the original. Renewal is for when the driver's license is not lost, but its validity period has expired, requiring all information to be updated before a new one is issued.
