You will need to remove the spark plugs and turn the engine over to blow the water out of the cylinders. You will also need to change the oil in the engine, transmission, differential. Just a warning most of the time when the engine hydro locks it can not be saved. Since a liquid can not be compressed it cause the rods to bend or break. But good luck to you with it.

water is a killer- have the car towed to a good mechanic- the fluids should all be changed, of course, but the wheel bearings will suffer also
