Coolant is one of the mixtures of water and antifreeze that will help regulate your engine’s temperature by circulating through it and preventing overheating. It also protects the engine from corrosion and ensures that the heat is away from critical parts. Monitoring your coolant levels not only prevents overheating but also extends your engine’s life.

When and How to Check

Regular coolant checks should be part of your routine maintenance, especially during oil changes or before long trips. Here’s how to do it:

  1. Let the Engine Cool: Never check the coolant when the engine is hot. Pressure from a hot system can cause burns.
  2. Locate the Coolant Reservoir: It’s a clear plastic tank near the radiator with minimum and maximum level markers.
  3. Check the Fluid Level: The coolant should be between the minimum and maximum marks. If it’s below the minimum, add more coolant.
  4. Inspect Color and Consistency: Healthy coolant is bright (typically green, orange, or pink) and debris-free. If it looks dark or muddy, consider replacing it.

Tip: Foamy or particle-filled coolant may indicate contamination or engine trouble. If you have doubts, consult a mechanic.

    • Safety First: Make sure the engine is cool.
    • Locate the Drain Plug: It’s at the bottom of the radiator. Place a pan underneath, then open the plug to drain the old coolant.
  3. Flush the System (Optional): You can flush the system with water to remove residue. Close the drain plug afterward.
  4. Add New Coolant:
    • Use a funnel to pour in the recommended coolant. Follow manufacturer guidelines for mixing with water if needed.
    • Fill the reservoir to the maximum mark.
  5. Bleed the System (if required): Some cars need the air to be bled from the system after a coolant change. Check your manual for instructions.
