How many kilometers should the Jetta timing belt be replaced?

[DiCali]

The timing belt should be replaced every 60,000 to 80,000 kilometers, with an inspection at 60,000 kilometers. The maximum usage should not exceed 80,000 kilometers. Below is relevant information: Timing Belt: The timing belt is a crucial component of the engine and is key to its proper operation. It is an important part of the engine's valve system, connecting the crankshaft and camshaft to ensure accurate intake and exhaust timing through a specific transmission ratio. If the timing belt breaks while driving, it can cause valve timing disruption, leading to severe collisions between the valves and pistons, resulting in deformation or breakage. The seriousness of this is self-evident. Replacement Interval: For timing belts, most manufacturers recommend replacement every 3 years or approximately 60,000 to 80,000 kilometers. The replacement interval varies depending on the engine's structure, with new vehicles potentially allowing for a slightly longer interval. The specific replacement cycle should be based on the vehicle's maintenance manual. Failure to replace the timing belt in time can lead to aging or even breakage, affecting the car's performance and causing engine failure.
