What are the effects of car coolant leakage on the engine?
2 Answers
Car coolant leakage can have the following effects on the engine: 1. Cause the engine to overheat; 2. Lead to cylinder scuffing, wear, and irreversible damage; 3. Corrode components inside the engine compartment. The functions of car coolant include: 1. Preventing engine damage due to overheating in summer by achieving cooling effects; 2. Preventing the cooling system from freezing and cracking after prolonged parking in winter. It is important to note that water should not be added when topping up coolant. Coolant itself contains anti-corrosion substances, and diluting it with water or adding water can cause cooling system malfunctions, and in severe cases, may even lead to component corrosion.
I found that car coolant leaks can have quite serious effects on the engine. Coolant is essentially the lifeblood of the engine's cooling system, primarily responsible for heat dissipation, antifreeze protection, and corrosion prevention. After a leak occurs, the cooling efficiency drops significantly, causing the engine to overheat rapidly—I've seen many cars start emitting white smoke within just ten minutes on the highway. High temperatures can lead to metal components expanding and deforming, such as cylinder head warping or cracking, piston seizure, and accelerated crankshaft wear, directly damaging the engine. Corrosion is another major issue—rust buildup in the water jacket can block circulation, reducing engine efficiency over time or even causing a complete breakdown. If not repaired promptly, a minor issue can escalate into a costly disaster. A friend of mine once had to spend thousands on a major engine overhaul due to neglect. That’s why I immediately check for cracks in the radiator, water pump, or hoses whenever I spot a leak.
