How many kilometers does it take to change the synchronous belt?

Please refer to the vehicle maintenance manual. The timing belt has a long history in the engine, with mature technology, low cost and low noise, but it needs regular inspection and maintenance, and generally needs to be replaced after 55438+ 10,000 kilometers.

Timing belt is responsible for the accurate matching of key parts of the engine, so it is very important for the normal work of the engine. Once the timing belt is damaged, the valve and ignition work will stop or fail, the engine will not work, and the cylinder head will be damaged in serious cases. Whenever this happens, the engine needs overhaul.

The timing belt is made of rubber and will age with time and the accumulation of the engine. Although the original factory will make a safety margin within the specified replacement cycle, it is best not to challenge this limit.

The timing belt or chain of the automobile drives the camshaft to control the opening and closing of the valve when the crankshaft rotates through the movement of the piston. If the timing belt breaks, the camshaft will stop rotating, which will directly cause the piston to discard the closed valve during the compression stroke, resulting in engine damage.
