Stretch-Fit Belts

VIDEO: Understanding Stretch-Fit Belts

A stretch belt may look similar to a serpentine belt, there are some key differences.

Over the years, the automakers have consolidated accessory-drive components such as the alternator, the air-conditioning compressor and the power-steering pump onto one belt. On most late-model vehicles, this is the serpentine belt.

However, in the late 2000s, automakers began using a new type of belt to take some of the load off the main accessory-drive belt. It’s called a stretch belt, or stretch-fit belt.
