To avoid such problems, Nissens Automotive is highlighting the issues to ensure that workshops know how to perform a right first-time compressor installation.
The AC compressor is the heart of the AC system and it is also one of its most expensive parts. The installation process can significantly impact both the lifespan and performance of the compressor, which means that if it is not installed correctly, it can fail prematurely. To avoid this problem, it’s crucial to follow the correct procedure and to be aware of the most common compressor failures.
The links in this short review highlight the most critical aspects of the installation procedure and provides essential tips for avoiding premature failures of the AC compressor.
