Is a Coolant Temperature of 102 Degrees Normal?

[Haymitch]

Coolant temperature of 102 degrees is normal. Below is an introduction about coolant: 1. Introduction: Coolant, the full name should be antifreeze coolant, meaning it has antifreeze functionality. Antifreeze prevents the coolant from freezing and expanding in cold seasons when the vehicle is parked, which could crack the radiator and damage the engine cylinder block. However, it's important to correct a misconception: antifreeze is not just for winter use; it should be used year-round. In regular vehicle maintenance, the engine antifreeze should be replaced every year. 2. Composition: Coolant consists of three parts: water, antifreeze, and additives. Depending on the antifreeze component, it can be classified into alcohol-based, glycerol-based, ethylene glycol-based, and other types of coolant. 3. Function: To prevent the coolant from freezing and causing the radiator or engine block to crack after the vehicle is parked in winter, the freezing point of the coolant should be about 10°C lower than the lowest temperature in the region, in case of sudden weather changes.
