Does Antifreeze Need to Be Replaced in Winter?

Car antifreeze replacement should be flexibly chosen based on different driving habits and environments, and is not related to the season. During daily vehicle use, it is important to regularly check the engine's antifreeze. Generally, manufacturers recommend replacing antifreeze coolant every 2 years or 40,000 kilometers. Below are some precautions for antifreeze usage: 1. Pay attention to storage methods: Car antifreeze should be stored in a cool place away from direct sunlight, with the bottle opening sealed to prevent oxidation reactions between the antifreeze and air during storage, which could affect its performance or even render it ineffective. 2. Internal cleaning of the cooling system during replacement: When replacing car antifreeze, the cooling system must be cleaned. If the cooling system is not thoroughly cleaned, impurities may remain, causing the new antifreeze to change color significantly in a short time and impair its performance. 3. Regularly check the antifreeze level: Although car antifreeze does not need frequent replacement, it is essential to check the fluid level regularly. The normal level should be between the MAX and MIN marks. If it falls below the MIN mark, replenish it with the same brand and model of antifreeze promptly. 4. Do not mix different antifreeze types: Different types of antifreeze contain different additives and should not be mixed, as this may cause sedimentation and reduce effectiveness.

What is the normal tire pressure for the Q5?

Audi Q5's factory-recommended tire pressure standard is 2.4-2.5 bar. Due to seasonal factors, tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. The Audi Q5's tire pressure monitoring system can be viewed on the central display. The system utilizes ABS wheel speed sensors to detect differences in rotation speeds between tires, determining if there is abnormal tire pressure, and will promptly alert if any irregularities are detected. If the tire pressure monitoring indicator light comes on (a yellow symbol featuring an irregular circle without a seal on top, four small spikes at the bottom, and an exclamation mark inside), it generally indicates one of the following three reasons: Abnormal tire pressure. Typically, the system will alert if pressure is below 1.8 bar or exceeds 3.0 bar. In such cases, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset. After inflating the tires, if the tire pressure monitoring system is not reset in time, it will continue to display the previously recorded data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor. The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, such as by impact, it can also trigger the tire pressure warning light. For sensor damage issues, the only solution is to replace it with a new component.

Can Flood-Damaged Cars Still Be Driven?

Yes, but it is not recommended. Flood-damaged cars pose significant safety hazards, meaning they often leave lingering issues. Electrical circuits are prone to short circuits or even fires. While they can be repaired to some extent, even after repairs, substantial safety risks remain. Most auto repair shops, including authorized service centers, are reluctant to work on flood-damaged vehicles due to the persistent issues, primarily contamination and electrical system problems. Below are relevant details: 1. Electronic System Failures: Modern vehicles are equipped with various functions, almost resembling a collection of electronic components. Non-professional off-road vehicles rarely have waterproofing for onboard electronics. After water exposure, electronic modules related to the engine are highly susceptible to short circuits due to rust and corrosion. Additionally, car wiring typically runs along the bottom edges of doors, making it easy to soak. If these modules or wiring fail, minor issues may cause a function to stop working, while severe cases can lead to vehicle damage or even fires from short circuits. 2. Engine Failure: When water levels exceed the engine's air intake, water naturally flows into the cylinders, creating an air-water mixture. While air is compressible, water is not. This means that when the crankshaft pushes the connecting rod to compress the piston, water resistance causes the connecting rod to bend and deform. If the owner attempts to restart the engine after it stalls due to water intake, the immense counterforce can cause the bent connecting rod to rub against the cylinder wall, instantly puncturing the engine block—resulting in astronomical repair costs. This is why it is crucial never to let the engine stall once the vehicle is submerged in water.

How Long Until a Car is Mandatorily Scrapped?

For household 5-seat sedans and 7-seat SUVs, non-commercial small and mini vehicles have no usage period limit. When the normal driving mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. In addition to the above-mentioned vehicles, small and mini non-commercial passenger vehicles, large non-commercial sedans, and wheeled special machinery vehicles also have no usage period limit. Commercial vehicles have a scrapping period, as follows: Small and mini taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles have a scrapping period of 10 years, and large taxi passenger vehicles have a scrapping period of 12 years. Public transport passenger vehicles have a scrapping period of 13 years, other small and mini commercial passenger vehicles have a scrapping period of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping period of 15 years. Mini commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out an "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and affix the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, after inspection and confirmation that they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Modification Form", "XX Province Vehicle Renewal Technical Inspection Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the inspection office for verification and signature. The license plates will be reclaimed, and the application will be submitted for approval according to regulations to complete the scrapping registration. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if a vehicle is damaged and cannot be driven back to the place of registration, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to non-commercial use, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or deregistration of a motor vehicle, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or deregistration; (2) The owner must have owned the original vehicle for more than three years.

What are the differences between National V and National VI vehicles?

The differences between National V and National VI emission standards are as follows: Different emission standards: The National VI emission standard is more than 30% stricter than National V. Excluding the influence of driving conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The National V standard was implemented nationwide on January 1, 2017. The National VI standard was implemented on July 1, 2019. Different principles: During the National V phase, diesel and gasoline vehicles had different emission standards. However, National VI adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: The National V standard was issued by the Ministry of Environmental Protection. The National VI standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: National V is represented by "V," while National VI is represented by "VI." Different monitoring requirements for plug-in hybrid electric vehicles: Compared to National V, National VI has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. The National V standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. National VI has two standards: National VIa and National VIb. Their limits are as follows: National VIa standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM per kilometer driven. National VIb standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM per kilometer driven. Affected by the National VI emission policy, although National V vehicles can still be used normally without restrictions on driving or license plates, their resale value will be significantly impacted. For car owners, if they purchase a truck on loan for cargo transport, the vehicle's depreciation after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, National VI vehicles, which have a longer lifespan and more road rights, are more advantageous.
