[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.
