What parts need to be repaired after a vehicle is waterlogged?

After a vehicle is waterlogged, the engine compartment needs to be repaired. Additionally, it is necessary to check whether the airbag computer connector and the body computer connector have been flooded, as well as to inspect the condition of the four wheel bearings. The hazards of a water-damaged vehicle include the following two points: 1. Interior impact: Prolonged soaking can cause materials such as carpets and seats inside the vehicle to deform, become rough, and produce odors, leading to bacterial growth. The wiring harness under the carpet may retain heavy moisture, and the circuits may experience short circuits due to dampness. It is best to replace all these soaked components; otherwise, they may cause post-waterlogging complications. 2. Door panel impact: The door panels contain soundproofing material that needs to be replaced after being waterlogged. The four-wheel bearings must also be replaced because the bearing seals contain lubricating oil. If not replaced, the oil can corrode and deteriorate, losing its lubricating function and compromising driving safety.
I think after a vehicle is flooded, a lot of areas need to be repaired. For example, the engine can't be taken lightly—if water gets into the engine, you have to check the spark plugs, engine oil, and intake system; otherwise, it might seize or get damaged when starting. The electrical system is also crucial—the battery wiring harness needs to be dried to prevent short circuits, and the AC ducts might accumulate water and start smelling, so they must be cleaned thoroughly. For the interior, wet seats and carpets must be completely removed, washed, and dried; otherwise, they’ll grow mold and stink over time, which affects health. The braking system is another concern—floodwater can corrode the brake discs, making them loose and endangering safety. In short, don’t rush to start the car; first, tow it to a professional shop for a full inspection. I once repaired a flooded car myself, and just cleaning the interior took half a day—it’s really troublesome, but safety comes first.
There are numerous areas that require repair after a vehicle is submerged in water. Firstly, if the engine gets flooded, it needs a thorough overhaul, potentially requiring replacement of the oil filter and inspection of the pistons for integrity. Electrical components like the ECU control unit must undergo drying treatment; otherwise, short circuits could paralyze the entire vehicle's electrical system. Interior components such as seats and flooring must be removed and cleaned to prevent mold growth, which can cause allergies. Brake discs and pads also need inspection for rust. If the water submersion depth is significant, even the exhaust system and chassis are prone to corrosion. Never attempt to start the engine to avoid causing further damage. It's advisable to file an insurance claim as early as possible, as it can cover a substantial portion of the costs. Safety should always come first.
