Does the Bora engine use a timing belt?

The Bora does not use a timing belt. The Bora is equipped with the EA111 engine, and the Volkswagen EA111 engine uses a timing chain. More information about the timing chain used in the Volkswagen Bora engine is as follows: 1. The timing chain installed in the Volkswagen Bora effectively addresses the shortcomings of timing belts. The timing chain, made of relatively strong steel, can solve wear issues, as metal is stronger than rubber. 2. The timing chain in the Volkswagen Bora's engine generally does not require replacement, but it is necessary to regularly inspect the condition of the timing chain to avoid chain stretching, which could prevent the engine's timing system from operating normally and affect the car's performance. 3. Advantages and disadvantages of the timing system: Timing belts are quieter, have less transmission resistance, and lower transmission inertia, which can improve the engine's power and acceleration performance, and are easier to replace. However, the downside is that they are prone to aging, have a higher failure rate, and result in relatively higher maintenance costs for the owner.
I've been driving for over a decade and am quite familiar with engine structures across various models. The timing systems used in different model years of the Bora indeed vary. For instance, the older 1.6L engines mostly used metal timing chains, which generally don't need replacement under normal driving conditions. However, newer Bora models like the post-2019 1.5L engines have switched to rubber timing belts that require periodic replacement. I've seen many cases where the belt suddenly snaps while driving, bending the valves instantly, with repair costs easily exceeding ten thousand yuan. It's recommended to inspect the belt condition every 6 years or 80,000 kilometers. If you notice fine cracks or frayed edges, replace it immediately. Don't wait for a breakdown to regret it—this is one expense you really shouldn't try to save on.
