What's going on when the antifreeze boils?
Recently, topics related to car maintenance and repair have become increasingly popular on major social platforms and forums, especially the issue of antifreeze boiling, which has triggered widespread discussions. This article will analyze in detail the causes, hazards and solutions of antifreeze boiling, and attach the hot topic data of the entire network in the past 10 days for reference.
1. Reasons for boiling antifreeze

Antifreeze boiling refers to the phenomenon that the antifreeze in the engine cooling system boils due to excessive temperature. The following are common reasons:
| Reason | Description |
|---|---|
| Insufficient coolant | The liquid level is too low, causing the heat dissipation efficiency to decrease and the temperature to rise rapidly. |
| Radiator clogged | Dust or debris blocks the radiator, affecting heat dissipation |
| Water pump failure | The water pump cannot circulate the coolant properly, causing local overheating. |
| Damaged thermostat | The thermostat cannot regulate the coolant flow properly, causing high temperatures |
| Antifreeze quality is poor | Inferior antifreeze has a low boiling point and boils easily |
2. The dangers of boiling antifreeze
Boiling antifreeze not only affects the normal driving of the vehicle, but may also cause serious damage to the engine:
1.Engine overheating: Sustained high temperatures can cause engine components to deform or be damaged.
2.Damaged cylinder gasket: High temperature and high pressure may destroy the cylinder gasket, causing oil and coolant to mix.
3.accelerated wear: The lubrication performance of engine oil decreases in high-temperature environments, aggravating engine wear.
3. How to prevent and solve antifreeze boiling
To solve the problem of antifreeze boiling, the following measures can be taken:
| measures | Specific operations |
|---|---|
| Check fluid levels regularly | Make sure the coolant is between the MIN and MAX marks |
| Replace high-quality antifreeze | Choose antifreeze with high boiling point and high temperature resistance |
| Clean cooling system | Regularly clean debris and dust on the radiator surface |
| Check water pump and thermostat | Repair or replace in time if any fault is discovered |

5. Summary
Antifreeze boiling is a typical symptom of vehicle cooling system failure. Car owners should regularly check the status of the cooling system, use high-quality antifreeze, and pay attention to the cleaning of the cooling system. If boiling is found, stop the vehicle immediately for inspection to avoid engine damage. Through reasonable prevention and maintenance, such problems can be effectively avoided.
