What Causes the Engine to Make a Gurgling Sound Like Boiling Water?
1 Answers
The occurrence of this phenomenon in the engine is related to the coolant. A lack of coolant or the use of poor-quality coolant can lead to this issue. This situation is more likely to happen in summer and is commonly referred to as "boiling over," which can affect the vehicle's performance and lifespan. Below are some related explanations: 1. Boiling Point of Antifreeze: Antifreeze is produced by different manufacturers, and the freezing and boiling points vary by brand. Currently, the boiling point of antifreeze is generally above 105°C. If high-quality antifreeze is used, the "boiling over" phenomenon will not occur. 2. The quality of antifreeze can be measured by the following two main points: (1) Antifreeze Effect: The freezing point of water is 0°C, while ordinary antifreeze can typically reach -40°C. High-quality antifreeze should achieve around -60°C, which is an important indicator of antifreeze quality. (2) Boiling Point of Antifreeze: The boiling point of water is 100°C, while antifreeze should at least reach 108°C or higher. This means that the lower the freezing point and the higher the boiling point, the greater the temperature difference, and the better the quality of the antifreeze.
