What needs to be repaired for a flooded car?

[MayaDella]

It is necessary to inspect the exhaust system and engine oil. Also check the spark ignition system and test cylinder pressure. Below is relevant information about flooded cars: 1. Severity: The severity of a flooded car depends on the water submersion height and whether the vehicle was started while submerged. 2. Under seats: If the water only reached below the seats (this height hasn't reached the vehicle's air intake position, nor the fuse box or dashboard position), the impact on the vehicle is relatively minor after thorough cleaning. 3. Cleaning: During cleaning, transmission fluid, engine oil, and brake fluid need to be replaced. Additionally, maintenance should be performed on the vehicle's braking system, exhaust pipe, and catalytic converter to further minimize the impact of flooding on subsequent vehicle usage.
