Used for installing serpentine belts for A/C compressors on N62 engines which are not equipped with automatic belt tensioners

• Some N62 powered cars require you to stretch the belt onto the A/C compressor and crank pulleys while others have a tensioner
• If your N62 powered BMW does not have a tensioner for the A/C belt you will need this tool
• Compare to BMW Factory Tool #641 040
