Why is water dripping from the Outlander ASX exhaust pipe?
3 Answers
Water dripping from the Outlander ASX exhaust pipe is a normal phenomenon. There is a small hole at the bottom of each exhaust pipe. If you notice rust spots on your car's exhaust pipe, you should check whether this small hole on the exhaust pipe is blocked and clean it promptly. The conditions for water dripping from the exhaust pipe are: 1. Correct air-fuel mixture ratio; 2. Normal engine cylinder pressure; 3. Normal exhaust temperature. The Outlander ASX is a model under GAC Mitsubishi, belonging to the compact SUV category. Its dimensions are 4366mm in length, 1780mm in width, and 1640mm in height, with a wheelbase of 2670mm. The car's top speed is 183 kilometers per hour, equipped with a 5-speed manual transmission, and the tire specification is 215/70R16.
I was also puzzled when I noticed water dripping from the Outlander Sport's exhaust pipe. This is actually a normal phenomenon after gasoline combustion. After we refuel the car, the engine combines hydrogen atoms from the fuel with oxygen in the air during operation, producing water vapor. When the exhaust temperature drops, this water vapor condenses into droplets on the cold inner walls of the exhaust pipe and drips out. This is especially noticeable after a cold start in winter, sometimes enough to wet a small patch of ground. As long as the dripping is clear water and not excessive, there's absolutely no need to worry. However, if the dripping is accompanied by thick white smoke or a strong gasoline smell, it might indicate a blown head gasket or water entering the engine, in which case you should immediately take it to a repair shop for inspection. My own car drips water after every cold start, and it's been running perfectly fine for five years.
When repairing a car, a car owner asked why there is excessive water dripping from the exhaust pipe. This is actually a good sign, indicating that the gasoline is burning very thoroughly in the engine, combining the hydrogen in the gasoline with the oxygen in the air to form water. When this water vapor passes through the tail end of the exhaust pipe and encounters the cold outside air, it condenses into water droplets and is expelled. This phenomenon is especially noticeable in cold weather, where you can even see white vapor coming out of the exhaust pipe. However, be cautious if the dripping water is green or pink, as it might indicate a coolant leak. Normally, the amount of dripping water is higher right after starting the engine and decreases as the engine warms up. It is recommended to regularly check if the drainage hole at the tail end of the exhaust pipe is clogged with carbon deposits, as a blocked hole can affect water drainage.
