At this time, check the cooling system and make a preliminary judgment according to the different sounds produced by the engine. The hiss of the engine means that the engine is overheated. Check the cooling system. The exhaust system is blocked, and the vacuum pipe leaks or breaks.

2, Golf (check the transaction price | detailed explanation of the model) The reason for the loud engine noise may be the overheating of the engine. At this time, the cooling system can be checked, and a preliminary judgment can also be made according to the different sounds generated by the engine. If there is a hissing sound in the engine, it means that the engine is overheated. Check the cooling system.

3. Hello! Regarding the problem of loud engine noise you inquired about, the loud noise of the engine should have a lot to do with the lubricating oil used. It is mainly to check the use of the engine oil. It is recommended that you change the engine oil with higher viscosity first.

1. Lack of oil, lack of oil may also cause similar problems, and the oil pressure is relatively low, so check the engine oil pressure. The engine will hug when accelerating, or it will also appear when decelerating.

Do you want to see whether it is tire noise, wind noise, or engine noise? These three situations are different. Wind noise is determined by the sealing performance of the whole vehicle when driving at high speed. Basically, there is no good solution according to the condition of the vehicle.

Road noise and tire noise are caused by vibration and noise caused by the friction between the tires and the road surface, so shock absorption is the best way to reduceThe vibration plate or special vibration damping plate and sound-absorbing mat and door seal can improve tire noise and road noise from the three sources of shock absorption, sound absorption and sound insulation.

. The piston knocks on the cylinder. When the engine is working, the sound made by the piston colliding with the cylinder wall is claimed to be knocking on the cylinder. The phenomenon is: (1) When idling, it makes a rhythmic sound of "bang, dang". (2) The sound decreases or disappears with the increase of temperature. (3) Discharge blue and white smoke. (4) Sometimes the engine is not easy to start or the power decreases.

To solve this phenomenon, you only need to brake vigorously several times in a row to remove the abnormal sound. There is a strange sound from the brake. Symptom description: The vehicle makes a relatively loud noise and abnormal sound when stepping on the brake.

Engine adjustment. Sound insulation treatment: noise reduction treatment can be carried out on the vehicle, throughInstalling soundproofing cotton can reduce noise. The soundproofing cotton can be installed on the engine cover, as well as the parts where the air conditioning pipeline and wiring harness pass. Engine adjustment: If you find that the engine noise is too loud, you can consider finding professional maintenance personnel for inspection and repair.

In winter, the sound of the cold car in the morning will be relatively louder. After the car is hot, the sound will be normal.

The engine is caused by the golf door when the speed is substituted, and the adjustment valve can be changed. Lack of oil, lack of oil may also cause similar problems. In addition, the oil pressure is relatively low, so the engine oil pressure must be checked.

The main problem of the exhaust system, the loud noise coming out of the exhaust pipe is in the exhaust system. Check whether the exhaust pipe is broken. Cooling system, there will be a sound when the engine starts. The engine is overheated, and the cooling system needs to be checked.
