Is the timing belt or chain used in the 2017 Besturn B50?

[Keith]

The 2017 Besturn B50 uses a timing belt. Timing belt: It is an important component of the engine's valve train system, ensuring accurate intake and exhaust timing by connecting with the crankshaft and matching a certain transmission ratio. The reason for using a belt instead of gears for transmission is that the belt produces less noise, has minimal self-variation, and is easy to compensate. Obviously, the lifespan of the belt is certainly shorter than that of metal gears, so the belt needs to be replaced regularly. Timing chain: The main function of the engine timing belt is to drive the engine's valve train, enabling the engine's intake and exhaust valves to open or close at the appropriate time to ensure normal air intake and exhaust in the engine cylinders. In models like the Volkswagen Jetta (EFI), Santana 2000, Bora, Audi, etc., the timing belt also takes on the task of driving the water pump.
