What are the effects of insufficient coolant in a sedan?

[CatherineFitz]

The effects of insufficient coolant in a sedan include: 1. In cold climates, it can cause the engine or radiator to freeze and crack; 2. It affects the radiator's cooling efficiency, preventing normal circulation and leading to overheating, which can damage the engine. Coolant is a special additive-containing fluid primarily used in liquid-cooled engine cooling systems. It provides excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. Automotive coolants are classified into ethanol-based, glycerol-based, and ethylene glycol-based types. They need to be replaced approximately every 2 years or 60,000 kilometers. Failure to replace the coolant for an extended period can degrade its quality, reducing its anti-corrosion properties and potentially damaging the radiator pipes.
