The timing belt is a part of the internal engine. It is impossible for the engine to run if the timing belt is not working properly. That is why you should go to the mechanic if you suspect that something is wrong with it. A ticking noise from the engine can indicate that something is wrong with your timing belt. You may also have a problem getting your car started. You can turn the key and nothing may happen.
Additionally, you may notice oil leaking from the motor. This is a serious problem that can cause your engine to overheat. An engine misfire is another sign that you should look out for. It is important to note that a misfire can cause a lot of damage to your engine. You may end up needing to get it replaced.
