Can a car run without coolant in summer?

[StGavin]

Car cannot run without coolant in summer. The function of coolant is to dissipate heat for the engine. Without enough coolant, the engine may be damaged. Coolant replacement cycle: For vehicles that operate for long periods of time, such as taxis, etc. Generally, high-quality coolant should be replaced once a year, while vehicles with shorter operating times can be replaced every two years or every 30,000 kilometers. To prevent excessive foam formation that would reduce the heat exchange performance between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolant can have a validity period of up to three years. If suspended matter, sediment, or deterioration/discoloration is found in the coolant, replace it promptly and clean the system. Coolant composition: The main components of coolant are: 50% purified water, 40% methanol, and 10% other substances. The basic indicators of coolant are freezing point and boiling point. On the market, coolants have freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.
