What Causes a Car to Leak Antifreeze?

[DiBennett]

The reasons for engine antifreeze leakage may include: 1: Leakage in the coolant reservoir Open the hood and observe if there are signs of antifreeze leakage around the coolant reservoir. If such signs are present, it can be confirmed that the coolant reservoir has a leak. A leak in the coolant reservoir will directly cause antifreeze leakage. 2: Aging of the water pump gasket If the vehicle has high mileage, it can cause the water pump gasket to age, leading to water pump leakage. A technician can open the hood, remove the water pump, and check if the gasket is deformed or leaking. If these signs are present, it confirms that the water pump gasket has aged. 3: Faulty electronic thermostat. A technician can use a computer to read the data stream of the electronic thermostat and observe its opening degree. If the opening is too small, it confirms a fault in the electronic thermostat. A faulty electronic thermostat can cause abnormal operation, resulting in excessive water flow and antifreeze leakage.
