What to Do When Water Enters the Car Cabin?

[StAshlyn]

Vehicle water ingress can be divided into two scenarios: 1. Water entering while the vehicle is in motion. For vehicles that stall due to water exposure, the repair shop needs to check for water traces in the intake and exhaust systems on the engine side. The intake system should be inspected in the following order: air filter, intake manifold, back of the valves, and inside the cylinders. For the exhaust system, the entire exhaust pipe should be removed and stood upright (with the exhaust outlet facing downward) to check for water drainage. If rainwater has entered the engine cylinders, the engine must be disassembled to remove the water. 2. Water entering while the vehicle is parked. For vehicles severely flooded while parked, the repair shop typically removes all interior components from the cabin. Then, they inspect wiring, ECUs, and other components for short circuits or burns, replacing damaged parts as necessary. As for waterlogged carpets and upholstery, they can be cleaned and dried.
