Coolant is as essential as engine oil! It cools your engine in summer and prevents freezing in winter. Let’s walk through some practical coolant tips to keep things running smoothly, without stress.
1. Should You Add or Replace Coolant When It’s Low?
- Normal Coolant Level Fluctuations: It’s normal for the coolant level to vary slightly, thanks to thermal expansion and contraction. The level may seem lower when the engine is hot—no need to panic!
- When to Check: Check the coolant level in the morning when the engine is cold. Avoid opening the cap on a hot engine, as the high pressure can damage the cap's seal, causing leaks over time.
- If the Level is Below Minimum: Simply top it up with coolant of the same color—no need to replace the entire system.
2. When Should You Replace Coolant?
- For New Cars: Coolant in new cars can last five to six years without needing a replacement. If the level drops a little after three years, just add coolant of the same color.
- For Older Cars: Cars seven to eight years old tend to lose coolant faster. In this case, a replacement every three years is recommended to maintain optimal performance.
3. Does Coolant Color Matter?
- Why Coolants Have Different Colors: Colors help identify different types of fluids and prevent accidental ingestion. However, different brands might use the same color with slightly different formulas.
- Avoid Mixing Brands: If you’re unsure which brand was used, have a professional flush the cooling system and refill it with new coolant. Make a note of the brand and color for future top-ups to avoid any issues.
4. Coolant Shelf Life
The shelf life of coolant is usually two years from the car’s production date. Using expired coolant might reduce its effectiveness, so it’s a good idea to replace it when necessary to protect your engine and ensure safe driving.
Quick Summary
Coolant may seem trivial, but it plays a crucial role in keeping your engine running smoothly. Check the level regularly, top it up when needed, and replace it periodically to avoid costly repairs.
Tip: Use coolant of the same color, but don’t mix different brands to prevent potential chemical reactions.
