Was the Truck Insured? Claim it as a Total Loss unless you want to take it completely appart dry it and put it back together. The engine and most of the elecronic components are destroyed.


This late model truck best to hope you had full coverage insurance cause its totalled. If you didn't have insurance and your stuck, you will have to drain all the fluids, use brake clean or something that will not leave a residue and clean all the differentials, transmission, if a 4X4 the transfer case, engine, make sure you remove al the spark plugs and turn the engine over by hand to make sure you get all,the water out of the cylinders and then put in a small amount of oil in each cylinder, then refill with proper lubricants, and inside you will have to strip it all down and get the upholstery and carpet cleaned including the sound deadening mats, now comes the expensive part, most likely all the electronics are toast so they will have to be repalced, all theconnectors will have to be disconnected dried and cleaned up, this includes all of those under the hood and engine, lights, everything and don't forget the new prccessors will have to be flashed for your VIN to make it run, after all this is done and you have it running get rid of it, of course you will have to state that it was a flood vehicle, or face the music. It makes no differance how clean and dry you get everything flood vehicles usually don't run very long just due to corrosion that gets into places you just can't clean.


With or without full coverage insurance, it's time to walk away from it. The vehicle, as others have said, is totalled. If you have full coverage insurance file your claim and let the insurance company tow it away. If you don't have full coverage insurance, junk it. Very sorry for your misfortune!! HTH. -Jim


A crusher is a good start.
