What are the possible reasons for water leakage under the car?
3 Answers
It could be due to aging or damage in certain pipes of the cooling system, a damaged radiator, or the air conditioning being turned on. Here are the specific explanations: 1. Air conditioning is turned on: If water leakage under the car is caused by the air conditioning being turned on, this is a normal phenomenon. 2. Radiator leakage: If the leakage is from the cooling system pipes or the radiator, it is recommended that car owners repair it immediately. 3. Water-cooled engine: Most cars use water-cooled engines, which rely on antifreeze circulating continuously within the engine to dissipate heat. 4. Two circulation paths for antifreeze in the engine: One is the major circulation, and the other is the minor circulation.
I remember last time my car was leaking water, I quickly got down to take a look and found that there are quite a few common reasons for water leakage under the car. It usually involves issues with the cooling system, such as aging and cracking radiator hoses or loose coolant tank connections leaking antifreeze; dripping water during air conditioning operation is normal condensate drainage, but if abnormal, it might be due to a clogged drain pipe; when the fuel system malfunctions, a hole in the fuel tank or a failed fuel pump seal can cause gasoline leakage; brake system leaks, such as seeping brake fluid pipe connections, are also very dangerous; and there’s the lubrication oil system, like an oil pan screw not tightened properly causing oil leakage. I suggest fellow drivers who encounter this issue first pull over, check the liquid color: green for antifreeze, clear water droplets are normal, black oil indicates an engine oil problem, to avoid vehicle breakdown or fire, and directly take it to a repair shop for a comprehensive check to be safe.
I always make it a habit to walk around my car after parking to check for any issues. Water leakage under the car can be caused by various factors. The main types include defects in the car's cooling system, such as cracks or small holes in the antifreeze pipes; normal dripping from the air conditioning system during cooling but excessive leakage when blocked; fuel leaks due to tank corrosion or loose connections; lubricant leaks like engine oil pan cracks; and windshield washer fluid pipe ruptures leaking blue-green liquid. Whenever I notice any leakage, I address it immediately, especially when there's a strong gasoline smell, as it poses a fire risk. After parking, I place a piece of paper underneath to identify the location and color: clear water is usually harmless, oily stains may indicate engine issues, and a pungent smell requires urgent assistance. Timely maintenance can prevent minor issues from becoming major problems, extending the car's lifespan and saving money.
