How many kilometers should the engine belt of a small car be replaced?
2 Answers
Since the engine belt is an important component of the engine, to avoid engine problems, 4S shops generally recommend replacing the timing belt after driving about 60,000 kilometers. For new cars, the timing belt can usually last 80,000 to 100,000 kilometers. Here is more information about the engine belt: Function: The generator belt is the outer belt of the engine, connecting devices such as the generator and compressor, ensuring functions like power generation for the car during engine operation. Reasons for aging: The belt is a rubber component. As the engine operating time increases, the belt and its attachments, such as the belt tensioner pulley, belt tensioner, and water pump, will wear out or age. Sudden temperature changes, exposure to sunlight, extremely cold weather, and prolonged friction can all accelerate the aging of the timing belt.
When I help friends with car repairs, I've noticed that the replacement mileage for a car's engine belt depends on the specific model and driving habits, not a fixed number. Generally, the vehicle manual suggests replacing the timing belt around 60,000 to 100,000 kilometers. If your car often operates in high temperatures or on rough roads, it might need earlier replacement, say around 50,000 kilometers. An aged belt is prone to breakage, which can cause the engine to stall or even damage parts, often leading to losses of thousands. I once encountered a car owner who exceeded the recommended mileage without replacement, resulting in a breakdown on the highway—the repair cost was ten times the replacement price. It's advisable to check the belt for cracks or looseness every 20,000 kilometers; regular maintenance saves both hassle and money. Additionally, modern new cars use more durable rubber composite materials, but it's still best not to take chances—getting a professional diagnosis is the most reliable approach.
