What's wrong with the loud noise of the Toyota Corolla

1. The reason for the loud noise of the Toyota Corolla engine: aging of the foot glue: the foot glue caused by the rough operation of the engine Abnormal sound of aging. This abnormal noise is caused by the premature injection time, so the oil supply advance angle should be readjusted.

2. It may be that the gap between the piston and the cylinder wall is too large. It is recommended to go to the 4S store of relevant majors for inspection. The reasons for the loud noise of the Corolla engine are as follows: 1.

3. There are many reasons for the loud noise of the engine. It may be that the spark plug is too old and needs to be replaced.It may be that the gasoline itself is not clean, or there is water in the oil line. In addition, the ignition line, vaporizer and oil pump also need to be checked.

4. When the engine noise becomes louder, the throttle valve should be considered first. If the throttle valve is dirty, you can consider cleaning it once. When the intake manifold leaks, when the air, gasoline steam and combustion exhaust gas that should not be entered enter the intake manifold, the mixture is too thick or too thin, causing the car engine to become louder.

5. The reasons for the hysterical sound problem of the engine can be divided into air filter, spark plug, ignition line, gasoline, gasoline filter, gasifier, oil pump and other problems. Check whether the air filter is dirty, whether the spark plug is old and has to be replaced, the ignition coil is broken, the gasoline is not clean, for example, there is water in the oil line.

What's wrong with the Corolla engine

1. It may be the gap between the piston and the cylinder wall. Big. It is recommended to go to the 4S store of relevant majors for inspection. The reasons for the loud noise of the Corolla engine are as follows: 1.

2. The reason for the loud noise of the Toyota Corolla engine: the aging of the foot glue: the aging of the foot glue caused by the rough operation of the engine.This abnormal noise is caused by the premature injection time, so the oil supply advance angle should be readjusted.

3. When the engine sound becomes louder, you should first consider the throttle valve. If the throttle valve is dirty, you can consider cleaning it once. When the intake manifold leaks, when the air, gasoline steam and combustion exhaust gas that should not be entered enter the intake manifold, the mixture is too thick or too thin, causing the car engine to become louder.

4. There are many reasons for the loud noise of the engine. It may be that the spark plug is too old and needs to be replaced, or the gasoline itself is not clean, or there is water in the oil line. In addition, the ignition line, vaporizer and oil pump also need to be checked.

Corolla twin engine soundLoud sound

1. It is normal for the engine of Corolla Twin Engine to be loud in the high-speed area. If you think the noise is very loud, you can make a whole car soundproofing. Corolla Twin Engine is a hybrid version of Corolla, which adopts an 8-liter naturally aspirated engine. This 8-liter naturally aspirated engine is an Atkinson cycle engine.

2. It is normal for the engine of the Corolla Twin Engine to make a loud noise after reaching the high-speed area. If you feel that the noise is noisy, you can make a full-car soundproofing Corolla Twin Engine is a hybrid version of Corolla. This car uses an 18-liter naturally aspirated engine. This 18-liter self However, the intake engine is the Atkinson cycle.

3. The new car Corolla twin-engine hybrid is particularly loud when the engine is not charging itself. WhenWhen the new car Corolla twin-engine hybrid engine is running, it may make some noise, which is a normal phenomenon. The mechanical parts inside the engine and the gasoline combustion process will produce noise.

What is the reason for the loud noise of the Toyota Corolla engine

The reason for the loud noise of the Toyota Corolla engine: the aging of the foot glue: the abnormal sound of the foot glue caused by the rough operation of the engine. This abnormal noise is caused by the premature injection time, so the oil supply advance angle should be readjusted.

It may be because of the lack of oil, so adding oil can solve the problem. The reasons and solutions for the abnormal noise of the Corolla engine are as follows: the oil is insufficient, so that all parts cannot be lubricated normally.

It is difficult to solve the abnormal noise of the Toyota Corolla engine. When the engine is working, the main sound sources are work explosion, exhaust sound waves, intake resonance, and parts movement. Except for these, it is an abnormal sound. The engine abnormal sound indicates that the technical status of a certain mechanism of the engine has changed.

The introduction of the relevant content of "What to do if the Toyota Corolla engine has abnormal sound" that everyone wants to know is as follows: The reason for the abnormal sound of the Toyota Corolla engine may be that the engine does not have enough oil, so there is no way to lubricate normally between the parts, and the sound of wear will occur. At this time, you can add engine oil to solve the problem.

What is the reason for the loud noise of the Corolla engine?

1. It may be that the gap between the piston and the cylinder wall is too large.It is recommended to go to the 4S store of relevant majors for inspection. The reasons for the loud noise of the Corolla engine are as follows: 1.

2. The reason for the loud noise of the Toyota Corolla engine: the aging of the foot glue: the aging of the foot glue caused by the rough operation of the engine. This abnormal noise is caused by the premature injection time, so the oil supply advance angle should be readjusted.

3. The specific reasons are as follows: when the engine sound becomes louder, you should first consider the throttle valve. If the throttle valve is dirty, you can consider cleaning it once.
