What to Do When the Coolant Boils Over?

[DaisyLynn]

Here are the steps to handle a coolant boil-over situation: 1. Pull over to the side of the road and let the engine idle for a while to allow the temperature to gradually decrease. 2. If the boil-over is caused by insufficient coolant, replenish it promptly after the engine temperature has dropped. 3. In case no coolant is available, as a last resort, you can add a small amount of water and proceed to the nearest repair shop for a replacement. Below are the reasons for coolant boil-over: 1. The radiator stops functioning, leading to excessively high water temperature. 2. The coolant is not circulating, either because the thermostat fails to open or the water pump is not working properly, resulting in a blocked water circulation system and causing boil-over. 3. Insufficient coolant. Low coolant levels can easily lead to boil-over. 4. Poor-quality coolant with a low boiling point is prone to boil-over.
