Why is water dripping from the Crown's exhaust pipe?
2 Answers
The reasons for water dripping from the Crown's exhaust pipe are: 1. The fuel has been fully burned in the engine; 2. Coolant from the engine has leaked into the combustion chamber. The functions of the exhaust pipe are: 1. To reduce vibration and noise; 2. To facilitate installation; 3. To extend the lifespan of the exhaust muffler system. The Crown is a 4-door, 5-seater mid-to-large sedan under the Toyota Group, with body dimensions of 5020mm in length, 1805mm in width, and 1480mm in height, and a wheelbase of 2925mm. The Crown is equipped with a 2.0L turbocharged engine and a 6-speed automatic transmission, delivering a maximum horsepower of 197.
After driving for so long, I often notice white smoke and dripping water from the exhaust pipe in winter. This is completely normal. When the engine burns gasoline, it produces water vapor, which condenses into water droplets when it meets the cold exhaust pipe. This is especially noticeable in cold weather or during short trips. To confirm if it's normal, just check if the coolant level is decreasing or if there's any pungent smell from the exhaust. Modern cars are even more remarkable—when exhaust passes through the catalytic converter, more water is produced, indicating the engine is working properly. If you're still unsure, you can have a mechanic check the gaskets or exhaust pipe welds. Of course, in summer or rainy weather, water splashed by the rear wheels might also land around the exhaust pipe—don't confuse the two.
