How many kilometers does a CVT steel belt need to be replaced?
2 Answers
Theoretically, the timing chain does not need to be replaced for life, but in actual situations, it needs to be inspected after 200,000 kilometers. Here are the relevant introductions: 1. The principle of CVT transmission: It mainly consists of two conical wheels and a steel belt or chain. The two conical wheels can be tightened and released through electro-hydraulic control devices, changing the diameter of the steel belt inside the conical wheels to achieve a change in the transmission ratio. 2. Advantages of CVT transmission: Since the CVT transmission has no mechanical gears, it is very smooth throughout the entire driving process, with almost no sense of jerking. The CVT has fewer parts, only a few hundred, and the fewer parts make the CVT highly reliable.
I've been driving a CVT car for several years and feel that the steel belt doesn't have a fixed replacement mileage; it depends more on driving habits. My car has now run 120,000 kilometers, and the steel belt is still functioning normally because I mostly drive in the city, rarely accelerate hard, or carry heavy loads. Regularly changing the transmission fluid every 60,000 kilometers is crucial, as dirty oil can accelerate steel belt wear, leading to slipping or breakage. If you hear unusual noises from the transmission or experience weak acceleration, it might indicate a problem that needs immediate repair. Maintenance records are essential. I check the transmission's condition monthly, and smooth driving can extend its lifespan. Replacing a steel belt isn't cheap, so avoiding racing and heavy hauling on mountain roads can save you this expense. Generally, an inspection might be needed between 100,000 to 150,000 kilometers, but don't rush to replace it if it's not broken.
