How many kilometers should the timing belt of Toyota Crown be replaced?
2 Answers
Toyota Crown uses a timing chain, which is maintenance-free. Here is the relevant information: 1. The main function of the engine timing belt is to drive the engine's valve train to open or close the intake and exhaust valves at the appropriate time, ensuring that the engine cylinders can normally intake and exhaust. 2. There is no specific requirement for when the timing chain needs to be replaced; it only needs to be replaced when the chain becomes deformed and produces abnormal noise after prolonged use. The service life of the timing chain is greatly related to the engine oil used for regular vehicle maintenance, as the chain does not directly rub against the sprocket but is lubricated by the engine oil.
I've been driving a Toyota Crown for almost 15 years, and timing belt replacement is crucial. It's generally recommended to change it every 80,000 to 100,000 kilometers—don't wait until it breaks. If the belt snaps, the engine can easily get ruined, costing several thousand to over ten thousand yuan in repairs. Pay attention to your driving habits; frequent short trips or high-speed driving can accelerate belt aging. During maintenance, ask the mechanic to check the belt for wear. If there are cracks, replacing it early is safer. As the car ages, parts are more prone to fatigue, so sticking to standard mileage maintenance can save you a lot of hassle. Old cars rely on maintenance—don't skimp on small expenses only to spend big later.
