What are the reasons for coolant leakage?
2 Answers
The reasons for coolant leakage include: 1. Sealing issues in the cooling system: The connection between the coolant reservoir and the radiator is not tightly sealed, leading to coolant leakage; 2. Pipe problems: Aging or cracked rubber pipes cause coolant leakage; 3. Radiator issues: Corrosion of the radiator results in coolant leakage. The main areas where coolant leaks occur are around the radiator. You can check the exterior of the radiator and the pipe connections for any signs of liquid. Significant coolant leakage will cause the engine temperature to rise, and the car's dashboard will display a temperature warning. It is advisable to inspect and repair the issue as soon as possible to prevent damage. Coolant, also known as antifreeze coolant, primarily functions to prevent freezing, cool the engine, resist corrosion, and prevent scaling. Coolant is colored to distinguish it from other liquids, making leaks easier to detect.
Coolant leakage is indeed a common headache, and I've seen plenty of cases with various causes. Mainly, it's due to cracks in the radiator caused by prolonged high-temperature corrosion leading to holes; aging and brittle hoses that rupture, or loose connections that easily leak; worn-out water pump seals allowing coolant to escape; improperly installed or cracked thermostat housings; and blown engine head gaskets, which can cause coolant to seep in—a more serious issue. If the heater core leaks inside the car, it can produce steam and wet the carpet. Additionally, a faulty radiator cap pressure regulation can lead to system overpressure and leaks. I must say, the most direct way to check is to inspect the ground under the engine for pinkish-green fluid stains when parked. If left unrepaired, coolant leaks can lead to engine overheating and total failure, resulting in hefty repair costs. I recommend regular maintenance to inspect hoses and the water pump, replacing old parts as a preventive measure.
