What Causes Oil Leakage in Car Air Conditioning?
2 Answers
Reasons for oil leakage in air conditioning pipes: The rubber sealing rings inside the transmission are subjected to alternating cold and warm temperatures over time, causing the sealing rings to lose a significant amount of plasticizers and softeners. This leads to corrosion, aging, and hardening issues. Initially, there may be oil seepage, which gradually progresses to oil dripping. Over time, the sealing rings may even break. More relevant information is as follows: Function of air conditioning: Car air conditioning is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the vehicle cabin to an optimal state. It provides a comfortable riding environment for passengers, reduces travel fatigue, creates good working conditions for the driver, and serves as an important ventilation device for ensuring safe driving.
I once encountered an issue with air conditioning oil leakage while driving, which is usually caused by aging seals or loose pipeline connections leading to refrigerant oil leakage. If you notice reduced cooling efficiency, oil stains under the car, or abnormally loud compressor noise when using the AC in summer, you should be alert. Unrepaired oil leakage can cause compressor overheating and damage, resulting in complete AC system failure and much costlier repairs. I believe it's important to have mechanics inspect AC seals during regular maintenance, especially for cars that are five or six years old as they're more prone to such problems. You can check AC pipelines for cracks or oil stains yourself, but avoid disassembling anything – professional repair is always the most reliable solution.
