How often should the timing belt of a Crown be replaced?

[IvanRose]

The timing belt of a Crown should generally be replaced every 50,000 kilometers. Once the timing belt shows signs of aging or cracking, it must be replaced immediately. It is generally recommended to replace the timing belt every 3 to 5 years or approximately 80,000 to 100,000 kilometers. The timing belt is a crucial component of the engine's valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a specific gear ratio. The Crown is a mid-to-large-sized sedan under the Toyota Group. The 2018 Crown model has a body length of 5020mm, a width of 1805mm, a height of 1480mm, and a wheelbase of 2925mm.

I've been driving a Crown for over ten years, and I usually replace the timing belt every 70,000 kilometers or 5 years. The manual recommends around 80,000 kilometers, but to be safe, I do it earlier. I remember one time when the belt aged, the engine almost got wrecked, and the repair cost tens of thousands. During regular maintenance, I always ask the mechanic to check the belt for cracks or looseness. Replacing the belt isn't too expensive, just around a thousand bucks, which is much cheaper than a major repair later. I'd suggest adjusting based on driving habits—if you often drive long distances or in high-temperature areas, the belt wears out faster and should be replaced at 60,000 kilometers. Regular maintenance keeps the car running longer. The Crown is reliable, but aging parts need attention.

Having worked in an auto shop for a long time and handled many Crown models, the timing belt is generally recommended to be replaced every 80,000 to 100,000 kilometers or every 6 to 8 years. I've seen cases where customers neglected to replace it, resulting in a broken belt that damaged the engine and caused repair costs to skyrocket. In practice, always use genuine parts for replacement to avoid failures caused by inferior products. It's also a good idea to check the tensioner and water pump while you're at it, as issues with these related components can shorten the belt's lifespan. Pay attention to unusual noises or unstable power during daily driving—these are warning signs. Don't delay; replace it promptly to ensure safety.

I always drive a Crown to pick up my family, and the timing belt is replaced every 60,000 kilometers without fail. Safety comes first—if the belt breaks, it could lead to a breakdown and affect driving. When replacing the belt, I also have other engine components checked. The cost is reasonable, just over a thousand yuan. The Crown is durable, but maintenance should never be overlooked. According to the manual, 80,000 kilometers is the upper limit, but I replace it earlier to avoid risks.
