How to Choose Coolant?

[DePiper]

Coolant selection method: The ethylene glycol content in coolant must meet the national standard of 89.86% to be qualified. When purchasing coolant, it's best to buy from supermarkets or shopping malls. Although more expensive, the coolant sold there are all qualified and up-to-standard products. Never buy coolant online as although cheaper, most are inferior and unqualified. Coolant is essentially a mixture of water and antifreeze, with a maximum temperature resistance of 110 degrees Celsius. The core substance of the mixture is ethylene glycol. Hazards of inferior coolant: 1. Can cause scaling in the radiator and engine; 2. Can lead to corrosion of car metal plates causing leaks; 3. Easily causes car engine overheating, leading to engine failure.
