Which components need to be replaced in a flooded vehicle?

[LeCourtney]

Flooded vehicles require replacement of the following components: 1. Engine: If the vehicle did not stall or hasn't been started after water ingress, replace the engine oil, oil filter, air filter, and sealing rings during the engine component disassembly for water drainage. If the engine stalled or was restarted, in addition to the above components, major engine repairs may be necessary including connecting rod replacement depending on the situation. 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 completely replaced if severely submerged. 4. Bearing components: If floodwater reached the engine hood and immersion duration was prolonged, it's recommended to replace all bearing components to prevent later rust-induced noise or damage, such as alternator, AC compressor, wheel bearings, etc. 5. Wiring harnesses: For vehicles submerged for several days, it's advisable to replace all wiring harnesses completely, including electrical component harnesses for motors, audio systems, AC control panels, ABS modules, etc.
