1. Wait for your engine to cool down. This is important because adding coolant to a hot engine can cause it to overflow.
2. Open the bonnet of your car.
3. Locate the radiator. The radiator is usually located at the front of the engine, near the top. It is a metal container with a plastic cap.
4. Remove the radiator cap. Be careful not to drop the cap into the radiator.
5. Add coolant to the radiator. Use a funnel to add coolant slowly to the radiator. Do not overfill the radiator. The coolant level should be between the "max" and "min" marks on the side of the radiator.
6. Replace the radiator cap. Make sure the cap is tightened securely.
7. Start the engine and let it run for a few minutes. This will circulate the coolant throughout the system and help remove any air bubbles.
8. Check the coolant level again after the engine has cooled down. If necessary, add more coolant to the radiator.
