Where to Add Car Antifreeze?

The antifreeze should be added to the car's radiator, which can be located by opening the engine hood. The full name of car antifreeze should be anti-freeze coolant, meaning it is a coolant with anti-freezing properties. Car antifreeze prevents the coolant from freezing and expanding in cold weather, which could damage the radiator and crack the engine cylinder liners. Antifreeze is not just for winter use—during regular vehicle maintenance, the engine antifreeze should be replaced, with higher replacement frequency for special-purpose vehicles. Functions of Antifreeze: Anti-Freeze Function: This is the most basic function of car antifreeze. The freezing point of antifreeze is relatively low, and using it in winter prevents the cooling system from freezing. Proper use of antifreeze ensures the car operates normally even in cold weather, which is the primary reason many car owners add antifreeze. Cooling Function: Car antifreeze is also known as coolant. When the car engine is running, it generates a large amount of heat, most of which needs to be dissipated through the cooling system. Due to its material composition, antifreeze has a relatively low boiling point, making it effective for cooling and heat dissipation. Anti-Corrosion Function: The car's cooling system is made of metal, which is prone to electrochemical corrosion over time. Severe corrosion can paralyze the cooling system. Antifreeze usually contains corrosion inhibitors to effectively prevent corrosion in the cooling system. Anti-Scale Function: Scale can easily form in the cooling system, adhering to the outer surface of the cylinder and significantly reducing thermal conductivity, thereby diminishing cooling efficiency. Antifreeze typically contains deionized water to prevent scale buildup. Precautions: Different types of antifreeze should not be mixed, as this may cause chemical reactions, sedimentation, or bubbles, reducing effectiveness. When replacing antifreeze, flush the cooling system with clean water before adding new antifreeze and water. Label any remaining antifreeze to avoid confusion. Since different antifreeze formulations have varying freezing points due to their composition and ratios, choose one based on local temperature conditions. The antifreeze's freezing point should generally be 10°C to 15°C lower than the local minimum temperature to prevent failure. If the antifreeze level drops due to a leak in the cooling system, add the same type of antifreeze. If the drop is due to evaporation, add distilled or soft water to the cooling system. If suspended particles, sediment, or odor are detected, replace the antifreeze entirely and clean the cooling system. Ethanol-based antifreeze is volatile, so take precautions against fire. If the engine overheats, do not open the radiator cap or shut off the engine immediately, as rapid temperature changes may cause antifreeze to spray, leading to injury or fire. If the ethanol level drops due to evaporation, replenish with 80% ethanol. Ethylene glycol is an organic solvent—avoid spilling it on rubber parts or painted surfaces, and take care not to let it contact the skin. If spilled, rinse immediately with water to prevent corrosion or skin damage. Antifreeze should be used year-round. Some drivers use antifreeze only in winter and switch to plain water in spring, only replacing it again in winter. This can lead to corrosion and damage in the cooling system, potentially causing the engine to overheat or even crack the cylinder head, significantly shortening the car's lifespan. For vehicles with high mileage, such as taxis, high-quality antifreeze should be replaced annually, while those with low mileage can replace it every two years.

What to Do When Experiencing Jerking During Low-Speed Braking or Acceleration?

Jerking during low-speed braking or acceleration is typically caused by faults such as a malfunctioning torque converter in the transmission, a faulty transmission oil pump, clogged oil passages, or excessively high or low transmission oil pressure. It is essential to promptly inspect and repair the issue, including cleaning the oil passages, fuel injectors, oil lines, and pipes. For automatic transmission vehicles, some jerking during initial acceleration is normal. If you need to accelerate quickly while driving, you should press the accelerator pedal firmly. In this case, the automatic transmission will downshift to increase the engine speed. Once the speed reaches a certain level, the transmission will upshift. After upshifting, the engine speed will drop noticeably, resulting in a relatively pronounced jerking sensation.

Is it illegal to convert a manual transmission to an automatic transmission?

From a legal perspective, converting a manual transmission to an automatic transmission is not illegal, but modifications should be done with caution as they may affect the annual inspection. A manual transmission can be converted to a pseudo-automatic transmission: By installing an electronic control system that assists the driver in operating the clutch, but gear shifting still requires manual operation. When shifting gears, the system controls a motor to automatically depress the clutch, and releases it after the gear is engaged, preventing stalling. The system also provides prompts when shifting is needed. Disadvantages of modification: After modification, the vehicle may fail the annual inspection. Unauthorized modifications can also affect insurance claims, as accidents caused by modified parts will not be covered.

How Long Can National V Standard Vehicles Be Driven After the Implementation of National VI Standard?

After the promulgation of the National VI standard, there is no impact on National V standard vehicles, and National V standard vehicles can be driven with confidence. The National VI standard is different. After the implementation of the National VI standard, National IV and National V vehicles can still be driven without significant impact in the short term. However, National III vehicles will be affected after the implementation of the National VI standard. As long as regular vehicle maintenance is performed, good driving habits are maintained, and all exhaust emission indicators meet the standards, National V vehicles can be driven on the road. Compared with National V, the National VI standard reduces nitrogen oxides by 77%, particulate matter by 67%, introduces limits on the number of particles, and tightens the durability requirements of emission control devices and the relevant requirements of on-board diagnostic systems.

Where is the air conditioning filter located on the Chery Fengyun 2?

Chery Fengyun 2 air conditioning filter is located at the upper left of the engine compartment, which is under the right wiper. The air conditioning filter sealing cover is fixed by two screws. Remove the two screws and lift the sealing cover to see the air conditioning filter, and then you can remove it. When the car is driving with the air conditioning on, it needs to draw in external air into the cabin. The air contains many different particles, such as dust, pollen, soot, grinding particles, ozone, odors, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene, etc. Without the air conditioning filter, once these particles enter the cabin, not only will the car's air conditioning be polluted and the cooling system performance reduced, but also the human body will have allergic reactions and lung damage due to inhaling dust and harmful gases, be irritated by ozone, and be affected by odors, all of which affect driving safety.
