Nebraska Sandhiller - 3/8/2016 01:06 Fighting range fire tonight, got my pickup hot. 7.3 diesel powerstroke. Filled it up out of the fire rig tank which had some dish soap in it. Do I need to flush it out and put in new antifreeze? Lightning fire, with wind. burned about 10 miles in rugged sand hills. Had fire departments from 60 miles away. Possibly 50 to 100 rigs showed up.
