What's with the loud engine of the maverick?

Maverick (view the transaction price | model details) The engine is very loud, which may be carbon deposition or the use of inferior engine oil. Generally, the problem can be judged simply by distinguishing the engine sound.

1. The hiss of the engine means that the engine is overheated. Check the cooling system. The exhaust system is blocked, and the vacuum tube leaks or breaks.

2, step on the accelerator, found that the acceleration is not obvious, lack of power, the engine has a hysterical sound. Causes: air filter, spark plug, ignition wire, gasoline, gasoline filter, gasifier, oil pump and other problems. Check whether the air filter is dirty, whether the spark plug is old and needs to be replaced, whether the ignition coil is broken, and whether the gasoline is dirty, such as water in the oil circuit. And check the oil pump.

3. The exhaust pipe makes a lot of noise, which is mainly caused by the exhaust system. Check whether the exhaust pipe is broken.

4, the engine has a kicking sound, like the sound of a pencil knocking on the table, the engine speed increases and the sound increases. Cause: There is dirt inside the engine. It is recommended to change the oil, filter the engine and clean the engine. There may be a valve problem.

5. When driving, the acceleration and ignition may be normal, but if driving at a constant speed, it is found that the engine speed is too high but it still seems that it can't be lifted. Check the coolant. If the oil pressure is too high or too low, check the oil pressure gauge. It is also possible that there is a problem with the ignition time setting, which can also lead to such symptoms. As for the others, it may be an internal problem of the engine, such as EGR valve blockage.

6. When the engine changes speed, it will make a clicking sound, as if something is patting metal. Cause: It is caused by gas cylinder valve, so the adjusting valve can be replaced. Lack of oil may also cause similar problems, and the oil pressure is relatively low, so it is necessary to check the oil pressure.

7. The engine will whir when accelerating, or it will appear when decelerating. In short, as the speed changes, the volume will also change.

Cause: The power steering oil is insufficient and filled with oil. The generator bearing may be damaged. When there is a problem with the power steering pump and water pump, it will also produce similar noise.

8. When you step on the accelerator, you will hear a bang, bang sound coming from the exhaust pipe. The sound may not be very loud, the car will not be abnormal when driving, and the fuel consumption will increase. It is recommended to check whether the muffler and exhaust pipe are damaged.
