The Toyota Yaris is equipped with a timing chain, which typically offers reliable performance for hundreds of thousands of miles without the need for special maintenance, unlike timing belts. However, like anything else, timing chains can still fail. If this happens, your engine may fail to start or, while driving, you might hear a loud noise as the engine smokes and shuts down. This could result in damage to your pistons and bending of your valves, which is a costly and undesirable situation. If you discover the need to replace the timing chain (ideally before it causes engine damage), the labor cost will range from $500 to $1,000, with parts costing between $100 and $250.
