Serpentine Belts vs Stretch-Fit Belts

In the late 2000s, automakers added a new type of belt to take some of the load off the serpentine belt. It’s called a stretch-fit belt, or stretch belt. GM, for example, started using stretch belts to power the air-conditioning compressor on some 2009 models with the LS V-8 engine. So, why stretch belts? Well, in addition to removing some of the load off the serpentine belt, stretch belts allow for better packaging and solve NVH problems that can occur with a longer serpentine belt. Less belt means less tension, and fewer noise and vibration problems.
