What is the boiling point of Shell coolant?
1 Answers
Shell All Season Coolant -30°C has a boiling point of 106°C, while Shell All Season Coolant (OAT) -45°C has a boiling point of 108°C. Shell All Season Coolant is of high quality and can be directly used in the engine cooling system without dilution, preventing "boiling over" phenomenon. The method to increase the boiling point of coolant is to add ethylene glycol, which is the main component of coolant. The proportion of ethylene glycol in coolant ranges between 20-60%. The more ethylene glycol added, the higher the boiling point and the lower the freezing point. However, it's important not to add too much, as it can have the opposite effect. The quality of coolant is mainly measured by the following two points: First is the antifreeze effect. The freezing point of water is 0°C, while ordinary coolants can generally reach -40°C. High-quality coolants should achieve around -60°C, which is an important indicator of coolant quality. Another factor is the boiling point of the coolant. The boiling point of water is 100°C, while coolant should reach at least 105°C or higher. The greater the temperature difference between the freezing point and boiling point, the better the quality of the coolant.
