What are the reasons for coolant leakage?
2 Answers
The reasons for coolant leakage include sealing issues in the cooling system, radiator problems, and pipe issues. Detailed explanations for coolant leakage are as follows: Cooling system sealing issues: Poor sealing at the connection between the antifreeze tank and the radiator in the cooling system can lead to coolant leakage. Radiator problems: Corrosion of the radiator can cause coolant leakage. Pipe issues: Aging and cracking of rubber pipes can result in coolant leakage, primarily occurring around the radiator. Check for liquid around the radiator's exterior and pipe connections. Significant leakage can cause the engine temperature to rise, triggering a temperature warning on the car's dashboard. Immediate inspection and repair are recommended.
When my car experienced coolant leakage, I carefully recalled the last repair situation and found that common causes include aging and ruptured hoses, radiator corrosion, or wear of the water pump seal. These components are prone to issues under high temperatures, especially rubber parts on older cars that tend to become brittle. Additionally, excessive system pressure can also lead to leaks at the expansion tank or joints. I once encountered a similar situation while driving in mountainous areas, where the engine temperature soared. During inspection, I checked the ground for green or pink stains to locate the leak. Once found, it must be addressed promptly; otherwise, engine overheating can damage pistons or cylinder heads, not to mention the danger of breaking down on the highway. I recommend checking the coolant level in the engine compartment weekly and topping up with dedicated antifreeze when low. Preventive maintenance is far more cost-effective and hassle-free than major repairs.
