Does driving a car in water have any impact?

[Deborah]

Driving a car in water does have an impact. When the exhaust pipe is submerged, the exhaust resistance increases significantly. Additionally, the resistance of the car moving through water itself is considerable, causing the engine speed to drop rapidly and leading to stalling. Here are some methods to identify flood-damaged and accident vehicles: 1. Check the car locks: Look for signs of being pried open, damaged, or filled with glue. Then use the key to open each door to see if the locks are from the same set and if each door lock can be turned easily. Note that if turning the key is very difficult or requires almost breaking the key to open, it might be due to flood damage causing the central control motor to rust and malfunction. 2. Engine compartment: Inspect the mounting brackets of the lighting and signal lamp groups in the engine compartment for breakage or looseness. Check the wire connectors and sockets; if there is a large amount of sediment or rust spots inside, it may indicate a flood-damaged vehicle. 3. Engine compartment inspection: Examine the wiring and vacuum pipes on the engine body, as well as the gaps between the high-voltage ignition coils and spark plugs for traces of mud. Assess whether the aging and cracking of the pipes and wiring match the car's age and check the condition of the fuel injector mounts. The presence of rust on springs can also help determine the likelihood of the car being flood-damaged.
