What Causes Water to Drip Under a Car Engine?

[PiperDella]

Water dripping under a car engine can be caused by the following reasons: 1. If the air conditioning is on, it might be condensation water from the AC system. Overfilling the coolant reservoir can also cause excess liquid to expand when the engine is hot, leading to overflow through the reservoir's drain tube. 2. If the air conditioning is off and water still drips, there might be a leak. Check the antifreeze level, inspect the radiator for any cracks, or examine if the windshield washer fluid tube is damaged and causing leakage. 3. It's normal for water to drip from the exhaust pipe. This water is formed by the condensation of steam produced during engine operation, indicating good engine performance and complete combustion. Common engine faults include: 1. The muffler emits a rhythmic "popping" sound at various engine speeds, accompanied by slight black smoke. 2. The engine cannot reach high speeds, and the vehicle experiences noticeable power loss during driving. 3. Difficulty starting the engine, sluggish acceleration, overall lack of power, occasional backfiring in the carburetor during sudden acceleration, and even engine stalling, along with elevated engine temperature.
