One major cause of antifreeze leaking in a car is a damaged or worn radiator. In time, radiators can become corroded and prone to holes or cracks.Continue Reading
Leaks around hose connections can also cause antifreeze to ooze out of the car. This is more common on the upper and lower hose assembly as corrosion or heat can cause cracks in the hoses or seals. Most car owners can fix this problem by tightening or replacing the hoses without much effort.
Another common cause of antifreeze leaks are cracks or holes in the radiator or heater hose. Typically, when this occurs, the hoses often spray coolant out while the car is running. When checking for this issue, people should be cautious when opening the hot to avoid being sprayed with hot coolant.
A water pump with a bad seal shaft, a damaged heater core or a bad head gasket are also reasons for a vehicle leaking coolant. These causes are harder to identify and typically require a mechanic to fix.
If a vehicle is leaking or low on antifreeze, it should not be driven. Driving it in this condition can cause it to overheat, which leads to even more mechanical issues.Learn more about Car Parts & Maintenance
The buildup of pressure caused by adding too much coolant to a car can cause the rupturing of hoses, internal pipes and even the radiator. When coolant is added to a car, it is cold, however, while the engine is running, the liquid starts to expand, causing a buildup of pressure. If the radiator is too full, this buildup of pressure is often too great for the internal workings of the car.Full Answer >
To add coolant to a car, open the hood, and remove the cap on the white plastic tank that is next to the radiator. Add a 1:1 mixture of coolant and water up to the full mark, and replace the cap.Full Answer >
A sweet-smelling aroma and antifreeze smell could indicate that the car's heater core is leaking. Other common signs of a bad heater core include a foggy windshield, a water surging sound inside the dashboard and wet carpeting on the front passenger side. Heater cores are responsible for circulating heat inside the passenger cabin by extracting heat from the water/antifreeze mixture.Full Answer >
If the antifreeze leaks from a car, the engine is likely to overheat. If the driver continues to operate the overheated vehicle, it is likely that major engine damage occurs. AA1Car.com says drivers should never ignore a hot warning light or temperature gauge that moves into the red.Full Answer >
