Is it normal to hear dripping sounds under the car after parking with no visible water?

[SanHarmony]

Hearing dripping sounds under the car after parking with no visible water is likely normal, possibly due to continued coolant circulation. Here are the details: 1. Causes: It may be the sound of engine oil dripping into the oil pan - a normal occurrence that requires no concern. The sound isn't caused by actual dripping water, but rather by certain components making noise due to thermal expansion/contraction or returning to position after operation. Parts like the catalytic converter, exhaust pipe, or turbocharger can produce similar sounds - all normal phenomena. Alternatively, it could be condensation water dripping from air conditioning operation, which is also normal. 2. Principle: After gasoline combustion, it forms water and carbon dioxide. At higher ambient temperatures, this remains as vapor that gets expelled before condensing. At lower temperatures, the vapor condenses into water droplets on the exhaust pipe walls.
