Nah..you empty the fuel tanks, pull the oil pan, let them dry. The point is that the vehicles do not need to be replaced, which would cost the city millions.
Disagree. I recently helped to recover a GMC truck with a 6.5 diesel that had been in the Red River for a couple of days (buddy thought the ground was a little softer and slid it into the river).
The engine was toast. wouldn't run even after we drained and dried it.
