Which car engines use chains instead of belts? What's the difference between these two?

The car engine is the heart of the car. Therefore, the engine's transmission belt is particularly important. Let’s talk about this key point below. The advantage of the timing belt is that it makes less noise, but the disadvantage is that it needs to be replaced; the advantage of the timing chain is that it does not need to be replaced, but the tightness needs to be adjusted for about 100,000 kilometers, and the disadvantage is that it makes a lot of noise; the advantage of the timing gear is that it does not need to be replaced, and it does not need to be replaced. Maintenance, the disadvantages are heavy weight and large inertia. Generally, the cost of follow-up service for timing belt is 5,000-10,000 yuan more than that of timing chain. For example, the biggest difference in maintenance between North and South Volkswagen's Shanghai Volkswagen Lavida and FAW-Volkswagen Bora's 1.6 engines can be said to be the maintenance of the timing belt. The FAW-Volkswagen Bora has more follow-up service expenses.

Manufacturers have strict replacement time limits, and the time and cost of replacing timing belts vary significantly for different engines.

Timing chain

only needs to be regularly inspected by an experienced technician and replaced during engine overhaul. Some also say it is the same as the engine life.
