Where to Add Car Coolant?

[Kate]

Car coolant can be added at a 4S shop. The types of coolant include: 1. Alcohol-based coolant; 2. Glycerin-based coolant; 3. Ethylene glycol-based coolant; 4. Propylene glycol-based coolant. The functions of car coolant are: 1. Preventing the car from freezing in low-temperature environments, which could cause the radiator and engine block to crack; 2. Preventing corrosion in the cooling system; 3. Reducing the formation of scale during circulation; 4. Absorbing heat to ensure the radiator can withstand high temperatures without boiling. Precautions for using car coolant are: 1. Prevent coolant leakage; 2. Coolant is toxic, so avoid ingestion; 3. Coolant is flammable, so take precautions against fire when using it.
