The auto timing belt is an automotive spare part made from rubber that maintains the sync in camshaft and crankshaft while properly timing the valves. It is a component of the engine which ensures things are going nicely and the powertrain of you car won’t fail. It sounds pretty simple to understand, but this is where things get complicated. Basically, the car timing belt interacts with various other parts of the engine, meaning, when you want to replace it, you are required to replace other spare parts as well. This includes tensioner, water pump along with pulleys. It is recommended to do so in order to avoid future hustle. If you won’t get them changed together, you will be required to do soon. So it is better to get it done at once.
