What is the belt next to the engine?

This is the engine's timing belt, which mainly drives the generator, water pump, and power steering pump. It generally needs to be inspected and replaced at 60,000 kilometers. It should be replaced early rather than late. Other related belts are as follows: 1. Timing belt: Most gasoline vehicles use this type of belt for transmission. It needs to be replaced around 60,000 kilometers. 2. Fan belt: Some vehicles may not have this belt, such as those with only one fan. For example, the older Santana models have a small auxiliary fan belt. 3. Other belts: These include the generator belt, water pump belt, power steering pump belt, and air conditioning belt, typically using one to three V-belts. High-end vehicles may use multi-groove belts, which last longer and are of better quality, but they are more expensive.
In my many years of driving experience, the belt next to the engine, commonly referred to as the serpentine belt or drive belt, plays a crucial role. Its main task is to drive accessories like the alternator, air conditioning compressor, and power steering pump, ensuring the car runs smoothly. Without it, the electrical system would fail, the battery would drain, and the car would struggle to start. I remember one winter drive when the belt became too loose, making a squeaking noise, and the air conditioning stopped working, nearly freezing me. Luckily, I made it to the repair shop in time. The lifespan of this belt is generally around 100,000 kilometers, but it depends on the car's condition and usage habits. During regular maintenance, pop the hood and check the belt's surface for cracks or signs of wear. If you spot any splits, replace it immediately—otherwise, a snapped belt could lead to expensive repairs. Safety first, so it's best to have a reliable mechanic inspect it regularly.
As a DIY enthusiast, I often tinker with the belt near the engine, which is typically the large belt that loops around multiple pulleys and drives components like the alternator and air conditioning. Checking it is straightforward: first, pop the hood and inspect the belt's surface for cracks or frayed edges; then press it with your hand—if it's too loose, it may slip, and if too tight, it accelerates wear. I always memorize the original routing before attempting to replace it myself. From personal experience, I recommend checking it every six months or whenever you hear a screeching noise. Replacing the belt requires specialized tools, so beginners should avoid attempting it to prevent engine damage. I also suggest adding belt inspection to your maintenance checklist, such as replacing it every 60,000 kilometers. Otherwise, if it snaps, the battery drains quickly, the AC stops working instantly, and driving in summer becomes unbearable. Opting for a high-quality brand belt can extend its lifespan and save you a lot of hassle.
