I can't image how to do this, but there must be a lot of people who know how to do it since all of the websites that deal in cars have huge warnings posted about people reconditioning flooded cars from Katrina and then selling them to unsuspecting people. This can't be easy since you would need to drain both the engine completely and the gas tank. For the engine I would guess that one would remove the spark plugs and remove the oil drain plug to let everything drain out, then hook a good battery up to crank the engine while the plugs and oil plug are still out. Then fill with oil and repeat the process. But, draining the gas tank is another thing all together, and before one can crank the engine, the gas lines would need to be clear of any water. But, maybe the gas lines only have gas in them and the gas tank simply filled with water from the filling tube.
Am a young car dealar with a passion for flooded vehicles but my problem now is how to restart the cars myself , how and what to do to make them run
I will appreciate every sugestion and ideas.
