Starting a 1996 Ford F350 7.3 Powerstroke Diesel in Alaska in 1 degree F subzero temperatures. This truck has been good to me, starts by itself without being plugged in down to about -25 F. It's amazing what good glow plugs and glowplug relays, good injectors,good batteries and a good starter will do. I always get request to see the truck do a cold start because folks don't believe it's possible, so here's another one... #coldstart #coldstartchallenge #alaska #diesel #ford #powerstroke
