What Causes Water Leakage Under the Chassis When the Air Conditioning is On in a Sedan?
1 Answers
The reasons for water leakage under the chassis when the air conditioning is on in a sedan are as follows: 1. Drainage from the drainage holes to prevent water accumulation in the body: The drainage holes are usually located on both sides of the front windshield wipers. During rainy days, water accumulated in the sunroof flows through the A-pillar ducts to this area, merges with water in the engine compartment inside the fenders, and is discharged near the wheel mudguards. The sunroof drainage holes are generally located at the four corners of the sunroof on the roof. After rainwater enters these holes, it flows through the ducts inside the A-pillar/C-pillar and is eventually discharged from the drainage outlets near the front and rear mudguards under the car. 2. Air conditioning system drainage: The dripping position of the car's air conditioning system is located slightly to the right of the middle of the front of the car. 3. Water dripping from the muffler and exhaust pipe at the rear of the car: It is also normal for water to drip from the muffler and exhaust pipe at the rear of the car, and this phenomenon commonly occurs in winter. Gasoline is injected into the cylinders and mixed with air. After complete combustion in the combustion chamber, it mainly produces carbon dioxide and water. At high temperatures, water is discharged into the atmosphere in the form of gaseous water vapor.
