When to Add Antifreeze?
2 Answers
Antifreeze should be added when the fluid level falls below the MIN mark. When replacing antifreeze, it is advisable to use the same brand, as different brands may have varying production formulas. Mixing different brands could lead to chemical reactions between additives, potentially rendering them ineffective. Prolonged failure to replace antifreeze can degrade its quality, reducing its anti-corrosion properties and damaging the radiator and pipes. It can also affect the boiling and freezing points, compromising the antifreeze or cooling performance. Do not wait until the antifreeze turns black to replace it, as this indicates severe deterioration and significant scale buildup, which may have already damaged the pipes.
I have extensive driving experience and have dealt with coolant issues multiple times. Let me tell you, the timing of adding it is crucial. Generally, you should add it when the level is below the MIN line, and it's best to check the transparent reservoir scale after parking and letting the engine cool. I make it a habit to check every quarter, with special attention before summer and winter because heat dissipation is vital in hot weather, and antifreeze is a must in winter. Adding it yourself is simple: open the cap, choose the same brand's dedicated coolant, pour it in up to the midpoint, and don't exceed the MAX line. It's recommended to replace it every two to three years. Once, I neglected it, and a little coolant leaked, almost causing the engine to overheat and stall. Since then, I've been more cautious about adding it. Regular maintenance has saved me from major repair costs, and my car enthusiast friends in the group have all learned this trick from me—it's both cost-effective and safe.
