Why is there water under the car chassis?

[McTeagan]

Here are the possible reasons for water dripping under the car chassis: 1. Drainage from water drainage holes designed to prevent water accumulation on the body; In addition to normal drainage from internal systems such as the air conditioning system, muffler, and exhaust pipe, the car chassis is equipped with specially designed drainage holes to discharge accumulated water from the body during rainy or snowy weather. These drainage holes include the engine compartment drainage hole, sunroof drainage hole, door drainage hole, and trunk drainage hole. 2. Air conditioning system drainage; This is normal during summer. 3. Lubricant oil leakage; There are many reasons for leakage, such as broken parts, aging oil pipes, loose screws, etc. 4. Antifreeze leakage; 5. Gasoline evaporation leakage. This could be due to a missing fuel tank cap or gasoline overflow.
