In a car, the engine is as important as the heart, and the various belts connected to it are an indispensable part of maintaining its normal operation. Today we will talk about these three key belts-generator belts, air conditioning belts and timing belts.

The first to appear is the generator belt, which is responsible for driving the generator to generate electricity and supply it to batteries and other electronic equipment. If this small rubber belt cracks or excessive relaxation, it will directly affect the stability of the vehicle electrical system. Under normal circumstances, it needs to be fully inspected every 50,000 to 100,000 kilometers.

Next, it's the turn of one of the protagonists who bring a cool feeling-the drive belt on the air-conditioning compressor. In the hot summer, it is hard to imagine the days without air conditioning! So how to choose a suitable and durable good helper? In addition to focusing on the material density, but also need to consider the anti-aging ability and operating noise level and other factors.

The last and most important role is the timing belt. Although it is just a few thin ropes woven, it is not surprising, but it is the soul of controlling the opening and closing time of the intake and exhaust valves to accurately match the rhythm of crankshaft rotation. Once broken, it may cause the piston to hit the valve causing serious damage or even scrap the engine. Therefore, it is particularly important to replace the period specified by the manufacturer on time.

Now that you understand your respective responsibilities and missions, how do you determine the specific model specifications that are suitable for your car? The easiest way is to consult the relevant parameter information clearly marked in the on-board manual; of course, you can also use the experienced eyes of professional maintenance technicians to help identify and confirm.

In order to enable these quietly dedicated behind-the-scenes heroes to serve for a long time, careful care is essential on weekdays. For example, regular application of special lubricating grease to reduce friction loss; avoid working in a high temperature and humidity environment for a long time, etc. are all effective means to extend the service life.

Finally, let's deepen our impression through a short story! Mr. Zhang forgot to replace the timing belt that had been in service for many years due to negligence. Unfortunately, he suffered a sudden failure and broke down on the roadside during a long journey. Not only was the valuable itinerary delayed, but the repair costs were prohibitive. Therefore, all car owners and friends must not make the same mistake again!
