How Often Should the Antifreeze in a Car Be Replaced?
1 Answers
The antifreeze in a car should be replaced every two years. The main functions of antifreeze are: 1. During winter when temperatures are low, it prevents the coolant from freezing and expanding, which could crack the radiator and damage the engine cylinder block or head; 2. During summer when temperatures are high, it effectively prevents boiling, avoiding overheating issues. The hazards of not replacing antifreeze for a long time include: 1. Evaporation of water in the antifreeze, leading to changes in the freezing point and affecting its effectiveness; 2. Loss of anti-corrosion, anti-rust, and rust removal functions for the engine, impacting the engine's lifespan; 3. Increased viscosity, reducing cooling and heat dissipation efficiency.
