I found out the hard way that if a car is flooded, DON”T TOUCH IT! The electronic parts will corrode almost immediately, and the rotating parts will get water in the bearings and fail in short order.
People don’t realize that all electric motor and alternator bearings are designed to keep lubricants in, but not water out. That is what the hood is supposed to do.
On the truck I was sold under false pretenses, the following parts failed within a few weeks.
Electric window motors.
Starter.
Alternator.
radio
AC and heater motor.
Then I found water in the differential oil.
Rust began to show through all over the truck. When I pulled out the door panels to replace the window motors I was shocked to find rust all over the unpainted interior parts of the door.
No, a flooded truck or auto is no more valuable than scrap iron.
