Will a Water-Damaged Car Be Affected After Replacing the Engine?

[McMorgan]

If the water damage is severe, merely replacing the engine will still have an impact on the car. Here is the relevant information: 1. Effects of Water Damage on the Engine: When the water level during submersion is higher than the engine's air intake, water can directly enter the cylinders, forming a mixture of air and water. While air is compressible, water is not. This means that when the crankshaft pushes the connecting rod to compress the piston, the water cannot be compressed, causing the connecting rod to deform and bend due to the resistance from the water. 2. Impact on the Interior: If the water level rises above the doors, the interior is likely to get flooded. Rainwater is not clean and contains many impurities. After the flood, the car interior becomes a highly humid greenhouse environment, which is an ideal breeding ground for mold. If the vehicle is not dried promptly, mold can quickly ruin the fabric and leather materials inside. Water-damaged cars are prone to issues with circuits, electrical components, and precision instruments.
