How to align the timing belt of the new Volkswagen Lavida?

[Giselle]

For the installation of the timing belt on the new Volkswagen Lavida, it is generally indicated by the angle of the crankshaft rotation before the piston reaches the top dead center, such as 10° before the top dead center, rather than in units of time. First, locate the position of the top dead center in the compression stroke of the first cylinder and loosen the spark plug of the first cylinder. Slowly rotate the crankshaft. When you hear a hissing sound, it indicates that the first cylinder is in the compression stroke. Open the inspection hole cover on the flywheel housing and continue to rotate the crankshaft slowly until the timing marks align. Below is an introduction to the timing belt: 1. The timing belt is a crucial component of the engine's valve system. It connects to the crankshaft and operates with a specific transmission ratio to ensure the precise timing of intake and exhaust. Clearly, the lifespan of the belt is shorter than that of metal gears, so it must be replaced regularly. Belts are used instead of gears for transmission because they produce less noise, have minimal self-variation, and are easier to compensate for. 2. Different vehicle models have different methods for aligning the timing belt. Generally, there are marks on the camshaft gear and crankshaft gear, and the marks should align with each other. However, it is recommended to refer to the vehicle's repair manual for the specific alignment method. 3. The timing belt connects the camshaft and crankshaft, controlling the opening and closing of the valves and the rotation of the crankshaft and the up-and-down movement of the pistons. If the timing belt is not aligned correctly, it will cause the valves to open and close at the wrong time, and the pistons to move up and down at the wrong time. Minor misalignment can result in insufficient power and vehicle vibration, while severe misalignment can cause the valves and pistons to collide, leading to damage. In such cases, the engine will stop working and require major repairs.
