Why is the sound of the Trumpchi GS4 air conditioning engine so loud?

[McMartin]

Generally speaking, insufficient engine oil or when the engine oil is cold and not yet heated, leading to insufficient oil pressure, can cause this phenomenon. If there are impurities or too much dirt in the engine oil, it may fail to effectively regulate the oil pressure, resulting in loud engine noise. Additionally, mechanical interference in the engine or blockage in the lubrication oil passage can also lead to such a situation. Since the actual vehicle cannot be seen, an accurate fault diagnosis cannot be made. It is recommended to go to a 4S store for inspection and repair. Below is some relevant information: 1. Main causes: Issues with the oil pickup, poor sealing of the rubber ring. Damage to the engine bearings. Reasons related to the exhaust pipe. When the engine starts cold in winter, the sound is louder than usual, which is a normal phenomenon. 2. Trumpchi: Trumpchi generally refers to GAC Trumpchi. GAC Trumpchi (referred to as Trumpchi) is a domestic brand created by GAC Group to enhance core competitiveness and achieve sustainable development.
