Why is the Mazda engine so loud?

[Adriel]

The reasons for the loud noise of Mazda engine are as follows: 1. The engine makes a sound similar to "puff puff": The unpleasant engine noise is most likely caused by the engine being too hot or too cold, and there is also a high probability that it is due to insufficient oil. 2. Engine overheating leads to loss of engine power: If the engine is active for a long time, causing the surface to overheat, the cooling system will fail. The first thing to do at this time is to check the cooling system. If there is a problem with the cooling system, it may cause blockage in the exhaust system because the vacuum tube is very likely to break. At this time, steam or hot air will come out of the engine, making some "squeaking" noises.
