What should I do if the car engine is loud and how to solve it?

1. Drive on the expressway for a period of time while ensuring safety.

Often driving at a low speed and stopping on urban roads for a long time, the engine is not fully released, which is prone to carbon deposition and leads to greater noise. So if you often drive in the city, you should take time out to run the highway.

2. Maintain the engine.

When you refuel, you can add something from fuel treasure, which can effectively remove carbon deposits. After all, the oil products in our country need to be improved, so it is necessary to maintain the engine properly.

3. Change the oil.

It is necessary to maintain the car regularly and on time. Even if the mileage is not reached, the old engine oil should be drained, because the engine oil will be oxidized. After a long time, its indexes will decline, which will not protect the engine well and produce noise. So change the oil in time.

4. Clean the throttle.

If the throttle valve is opened for a long time, it will hide dirt and shelter evil people, so the engine noise is really too loud, probably because the throttle valve is dirty. It will be much better after cleaning in a professional repair shop.

5, do sound insulation.

The noise may also be caused by the poor sound insulation performance of our car. Due to the aging of various sound insulation protection, the originally inaudible sound is introduced into the car, so doing sound insulation can also reduce noise.
