What are the reasons for air leakage in the dryer assembly?
2 Answers
Air leakage in the dryer assembly may be due to a faulty desiccant pressure regulator valve. Solutions: Simply weld or replace the damaged part, replace the O-ring if it is worn out, or clean the check valve and inspect the pipeline behind the dryer to locate the leak and ensure it is sealed. This will resolve the frequent air leakage issue in the dryer. Usage Notes: After prolonged use, the drying cylinder in the dryer will lose its drying function. It is recommended to replace the drying cylinder annually. Do not arbitrarily adjust the pressure adjustment screw to prevent inaccurate unloading pressure and thread damage, which could render the dryer unusable. Regularly clean the check valve and inspect the pipeline behind the dryer to locate leaks and ensure they are sealed.
As a seasoned veteran with years of car repair experience, there are several key reasons for air leaks in the dryer. The most common issue is aging seals, where rubber components harden and crack under the high temperature and pressure of the AC system, losing their sealing ability and causing leaks. The dryer itself may also develop cracks or fractures, especially after rough roads or accidental impacts. Improper installation is a major problem, such as loose screws or misalignment, leaving gaps. Moisture buildup or contaminants corroding components, particularly at joints or internal valves, can lead to leaks over time. Air leaks reduce AC cooling efficiency, increase compressor strain, and raise repair costs. It's advisable to regularly check connections for oil stains or unusual noises—simple fixes like replacing seals or the dryer can resolve the issue, but professional service is recommended for safety. Pay attention to AC performance while driving to catch issues early and avoid major repairs.
