Why is water dripping from the Vios exhaust pipe?
2 Answers
Vios exhaust pipe dripping water is caused by: the formation of water vapor and carbon dioxide after complete combustion of gasoline, which is a normal phenomenon. The water dripping from the car's exhaust pipe is not due to internal component damage causing leakage, but rather the result of water vapor produced after gasoline combustion. This vapor accumulates in the exhaust pipe, cools down, and then flows out, indicating that the engine is working normally and combustion is efficient. The dimensions of the Vios are 4300mm in length, 1690mm in width, and 1490mm in height, with a wheelbase of 2550mm. The display on the right side of the dashboard is highly integrated, showing time, mileage, and fuel gauge for easy reading, while the left side features the tachometer and speedometer.
I've been driving for over a decade, and water dripping from the exhaust pipe is extremely common. Especially during cold starts in winter, when white smoke from the exhaust pipe comes with water droplets dripping down, it indicates good engine combustion! Gasoline burns completely to produce water vapor, which condenses when it meets the cold exhaust pipe wall, just like water droplets forming on a pot lid when boiling water. However, two things to note: if the water volume is particularly large like a faucet, or if there's bluish-white smoke with a sweet smell, it might be coolant leaking into the combustion chamber. If the water temperature is normal and the exhaust has no strange odor, there's no need to worry—it actually proves your car is in good condition. My Vios ran for eight years, and the rust at the exhaust pipe outlet was slower than others, precisely because the drain hole frequently let out condensed water.
