Stretch Belt System Explained:
- What is a Stretch Belt? Stretch belts differ from traditional serpentine belts by offering self-tensioning capabilities, reducing the need for tensioners. They are ideal for components like water pumps, A/C compressors, and power steering pumps, improving noise, vibration, and harshness (NVH).
- OEM Adoption: More manufacturers are shifting to stretch belts for improved packaging and reduced system complexity, making them a practical choice for newer engines.
