What Is A Serpentine Belt And Why Is It Important?
If you look on the side of your transversely mounted engine, you'll see a thin belt that winds through several pulleys. That's the serpentine belt, and it's made of highly reinforced rubber. If you have a conventionally mounted engine, the belt is on the front. The serpentine belt powers many parts within the engine, including:
- Water pump
- Air conditioner compressor
- Power steering pump
- Air pump (if applicable)
The serpentine belt may seem like a simple part. Yet, it's very important because without one, the above parts will lose power. For a more thorough explanation of serpentine belts, check out this post.
