A special tool that may be needed when replacing a serpentine belt or automatic tensioner on a transverse-mounted engine in a front-wheel drive vehicle is a special serpentine belt removal tool. The tool has a long, flat extension handle that allows a socket to be placed on the tensioner bolt so the tensioner in a tight engine compartment can be easily rotated to relive pressure on the belt. Without this tool, the job is nearly impossible on some vehicles.
