1. Damaged or Loose Radiator Cap: A faulty or loose radiator cap might not create a sufficient seal, causing antifreeze to overflow and leak out.
2. Cracked or Leaking Radiator: A damaged radiator can develop cracks or leaks, leading to antifreeze loss. Look for visible cracks or drips under the car.
3. Malfunctioning Thermostat: A faulty thermostat might prevent the antifreeze from circulating correctly, causing it to overheat and blow out of the system.
4. Defective Water Pump: A broken water pump can lead to reduced coolant circulation, overheating the engine, and subsequent ejection of antifreeze.
5. Blown Head Gasket: Engine head gasket failure can lead to compression leaks between the cylinders, combustion chamber, and cooling system, pushing antifreeze out of the car.
6. Damaged or Blocked Radiator Hose: Damaged radiator hoses can leak or become blocked, obstructing coolant flow and causing pressure buildup in the system, resulting in antifreeze expulsion.
7. Faulty Heater Core: A defective heater core can cause leaks within the car's heating system, allowing antifreeze to escape into the interior or under the vehicle.
8. Faulty Freeze Plug: Freeze plugs or core plugs can become corroded or damaged, leading to antifreeze leakage. These plugs are found in the engine block and cylinder head.
9. Overflow Tank Issue: An issue with the overflow tank, such as a crack or faulty connections, can result in antifreeze leakage.
10. High Coolant Pressure: Excessive pressure within the cooling system due to a faulty pressure sensor or issues with the cooling fan or water pump can cause antifreeze to expel out.
Note: If you notice antifreeze leaking, address the problem promptly, as it can lead to engine overheating and other significant complications if left unattended. Consulting a qualified mechanic is recommended to pinpoint the exact cause and ensure safe vehicle operation.
