Is a Coolant Temperature of 90 Degrees Normal for a Car?
1 Answers
A coolant temperature of 90 degrees is normal for a car. Here is an introduction to coolant: 1. Overview: Coolant, also known as antifreeze coolant, is a liquid with antifreeze properties. It prevents the coolant from freezing in cold weather, which could otherwise cause the radiator to crack or damage the engine cylinder block. 2. Composition: Coolant consists of water, antifreeze agents, and additives. Based on the antifreeze agent used, it can be classified into types such as alcohol-based, glycerol-based, and ethylene glycol-based. 3. Function: To prevent the coolant from freezing in winter and causing damage to the radiator or engine block, the freezing point of the coolant should be about 10°C lower than the lowest temperature in the region, preparing for sudden weather changes.
