What Causes an Increase in Coolant?

[OHannah]

The main reason for an increase in coolant is engine cylinder leakage. Below is some information about automotive coolant: 1. Coolant is a crucial substance in the cooling system, circulating in the radiator and carrying away engine heat through the pipes. In addition to antifreeze and cooling, it also has excellent properties such as preventing boiling in summer, rust removal, and corrosion resistance. 2. The replacement cycle for coolant is approximately 2-3 years or around 60,000 kilometers. Generally, within this period, the coolant can perform effectively. However, it should be replaced earlier if the vehicle is used frequently or operates in harsh driving conditions. Extended content: Consider replacing the coolant if the following situations occur: 1. The color of the coolant in the reservoir has changed significantly from its original color; 2. Sediments or floating impurities are visible in the coolant; 3. The coolant level has exceeded the minimum limit; 4. Instrument testing shows insufficient freezing point of the coolant; 5. The engine temperature is too high.
