What are the effects of insufficient coolant in a sedan?

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.
Insufficient antifreeze can lead to inadequate engine cooling, causing overheating. Having driven for many years, I've seen numerous cases where low antifreeze levels caused engines to boil over. Once the cooling system is insufficient, heat cannot be dissipated in time, leading to potential cylinder head gasket failure, engine block deformation, or even complete engine failure. When driving under high temperatures, you might smell burning odors or hear unusual noises. Additionally, antifreeze also prevents freezing and corrosion. If the fluid level is low in winter, freezing can cause expansion and damage hoses or radiators. During every maintenance check, I inspect the coolant reservoir to ensure the level is between the minimum and maximum marks. When topping up, use a mixture of dedicated antifreeze and distilled water—avoid adding tap water arbitrarily to maintain effective rust and corrosion prevention. Neglecting this small issue can cause a significant drop in your car's value.
