What to Do When the Car Air Conditioning Compressor Belt Slipping?
2 Answers
When the car air conditioning compressor belt slips, it is necessary to check whether the compressor is stuck or has excessive resistance. The functions of the air conditioning filter include the following three points: 1. Provide fresh air: It can prevent the car windows from fogging up, ensuring clear visibility for the driver and safe driving; it supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety; it effectively sterilizes and deodorizes. 2. Ensure safety and hygiene: It keeps the cabin air clean and prevents bacterial growth; it effectively separates solid impurities such as dust, filter powder, and grinding particles from the air; it effectively blocks pollen, ensuring that drivers and passengers do not suffer from allergic reactions that could affect driving safety. 3. Adsorb harmful substances: It adsorbs moisture, soot, ozone, and odors from the air, with strong and durable moisture adsorption capabilities.
I found that when the AC compressor belt in my car slips, it's mostly due to a loose belt or oil contamination. At this time, the AC won't cool properly, and there might be a screeching sound. Last time, I handled it myself: first, turn off the engine, press the belt with your hand to check how loose it is—generally, about 1 cm of play means it's too loose. Adjust the tensioner screw to tighten it a bit, but remember to use a wrench carefully to avoid hurting your hand. Cleaning the pulley is also important; wiping off oil or dust with a cloth can improve the situation. If the belt has many cracks or severe wear, it's time to replace it, otherwise, it might completely break and damage the compressor. I recommend buying an OEM belt and replacing it yourself—it saves money and hones your DIY skills. But if you're really unsure, it's better to visit a repair shop to avoid damaging parts and incurring higher costs. Regularly check it every few months to prevent such minor issues.
