What parts need to be replaced for a Level 2 flooded vehicle?
2 Answers
For a Level 2 flooded vehicle, the following parts need to be replaced: 1. Engine: If the vehicle did not stall or was not started after water ingress, the engine oil, oil filter, air filter, and sealing rings during the drainage of engine components need to be replaced. If the vehicle stalled or was restarted, in addition to the aforementioned parts, the engine connecting rods may also need to be replaced based on the situation, requiring an engine overhaul. 2. Transmission: Transmission fluid and transmission filter. 3. All vehicle fluids: All vehicle fluids, including engine oil, coolant, power steering fluid, brake fluid, etc., must be replaced if the water ingress was severe. 4. Bearing components: If the water level reached the engine hood and the soaking time was relatively long, it is recommended to replace components with bearings to avoid rust-induced noise and damage later on, such as the generator, air conditioning compressor, and wheel bearings. 5. Electrical circuits: Depending on the extent of water ingress, damaged electrical components and wiring need to be replaced.
Recently helped a friend deal with this kind of flood-damaged car. For a Level 2 water submersion where the water reached below the seats, a comprehensive overhaul is mandatory. All electrical connectors in the car must be disassembled, derusted, and dried. The air conditioning controller inside the dashboard has a 90% chance of needing replacement, and all carpets must be discarded to prevent mold odors. Key areas to focus on: the alternator and starter must be disassembled for maintenance, and the differential fluid must be completely replaced. Car enthusiasts often overlook clogged sunroof drain tubes—it's recommended to use an air gun to clear them while you're at it. Finally, a heads-up: the repair budget for this kind of work starts at at least 20,000 yuan. It's best to go straight to a professional auto repair shop for reliable service.
