Tire inflation valve core leakage measures introduction: The usual place where the valve leaks is the rubber washer under the screw. You can go to a repair shop and ask a mechanic to tighten it with a valve core wrench, or use small tweezers to insert into the valve core and tighten it. You can also use soap bubbles to check. If the leak is around the outer part of the valve core, you can only replace the inner tube. Additional information: 1. Function of the valve core: The valve core is installed inside the main body of the valve, and its function is equivalent to a one-way valve, used to prevent the inner tube from leaking and to check and adjust the air pressure. To prevent the main body's inner hole from being blocked and leaking, a valve cap is used to seal the valve's inner hole. The valve cap can also serve as a tool for installing and removing the valve core. 2. Valve core maintenance: The rubber of the valve may age over time, leading to leaks. Driving with insufficient air can cause the tire to be damaged, so the valve should be checked regularly.

I've encountered quite a few cases of leaking tire valve cores at repair shops before. The main causes are usually loose valve cores, aging seals, or dust contamination. The solution is quite simple - you can first try gently tightening the valve core with a valve core wrench to see if it still leaks. If the air leakage continues, then you'll need to replace the valve core. Specialized tools and valve cores can be purchased for just a few dollars at auto parts stores or online, and keeping a set in your car for emergencies is very practical. For routine maintenance, it's recommended to regularly check tire pressure and valve condition, and replace the valve core when changing tires to avoid these issues. Insufficient tire pressure not only increases fuel consumption but also makes blowouts more likely. Addressing these problems promptly can save you a lot of trouble. Overall, you can learn to do it yourself in one go - it's both cost-effective and safe.

(5) Tractors and other motor vehicles shall be inspected annually. Operational vehicles passing safety inspections within prescribed periods need no repeated inspections. (6) Vehicles exceeding scrapping age cannot be transferred (sold), but can continue operating. For sales, owners should first obtain scrapping certificates (canceling vehicle records) at vehicle management offices. Motor vehicles can apply for annual inspection within 3 months before the inspection date.

All inspection dates follow the registration date on the vehicle license.

Can a Car Compressor Leaking Refrigerant Be Repaired?

Car air conditioning compressor refrigerant leaks can be repaired, but due to the complex structure of car air conditioning compressors, the repair process requires considerable time and incurs high costs. Therefore, repair shops usually opt to replace the compressor entirely. Relevant information is as follows: Connection pipe tubing: The connection pipes between the indoor and outdoor units of the air conditioner, if bent at too sharp an angle, can cause cracks in the tubing leading to refrigerant leaks or loss. Improper secondary installation of parts: If there are leaks in the refrigeration system, replacing parts without ensuring a tight secondary installation can result in refrigerant leakage points in the pipelines and refrigeration system.
