What to Do When the Car Coolant Level is Low?
2 Answers
If the car coolant level is low, it should be replenished promptly. The consequences of insufficient coolant include: 1. Causing the engine radiator to overheat; 2. Potentially damaging the engine. The reasons for low engine coolant levels are: 1. Internal engine leakage; 2. Leakage at connection pipes; 3. Radiator seepage; 4. Poor sealing of the radiator cap; 5. Damage to the radiator cap's air valve. The steps to add engine coolant are: 1. Unscrew the radiator cap and open the radiator drain valve; 2. Insert a rubber hose into the radiator; 3. Flush the radiator with water; 4. Drain the clean water and close the radiator drain valve; 5. Pour antifreeze into the radiator filler hole; 6. Tighten the radiator cap and the reservoir cap; 7. Start the engine and let it idle for 3 minutes; 8. Top up the antifreeze to the MAX mark.
If I notice a decrease in coolant level, I'll first stay calm and avoid hastily starting the engine, as insufficient coolant can lead to engine overheating and damage. When the car is cool, I'll open the hood to check if the reservoir's fluid level is between the minimum and maximum marks. If it's low, I'll add the appropriate coolant, making sure to choose the type and color that matches the original vehicle specifications, such as the same brand of antifreeze, to prevent chemical reactions from mixing different types. Then, I'll carefully inspect the radiator, hoses, and connection points for any obvious signs of leaks or wet spots. If no leaks are visible, it might be natural evaporation due to hot weather, so I'll start the car and let it idle for a few minutes before turning it off to see if the level stabilizes. If the issue persists or the level drops significantly, I'll definitely need to visit a repair shop for a professional inspection, as there could be hidden cracks or pump failures. I make it a habit to check the coolant level monthly, topping up or replacing it as needed to prevent such unexpected issues.
