I have many. -40 and colder. Stupid cold. Only thing you can do, if you don't have electricity near by or a generator, is start a fire near by. Burn it down to coals. Keep the fire going, this takes awhile... Clear the snow from under the engine. And slowly start feeding the coals under the engine bay. Not too much. Takes a couple/few hours but works. Or if if big equipment start shovelling lots and lots of coals, or just get th fire under it... Try not o melt any wires... Oh by the way... Have fun getting the fire going! Handy if some nice person left you a picnic table close by. (Hypothetically speaking, if I were to do that, I would very much like to hypothetically appologize for robbing your picnic table for my fire) I still have no idea what tat table we doing out there.... ... Now for those who are smarter than me, my suggestion, just don't shut the damn thing off at those temps. Let it idle all night. For those who are even smarter, check your fuel level first!
Oh and don't forget, at those temps, you coolant will be slushy, be careful! Believe it or not, you can over heat the engine! I had a gas engine once with slush for coolant. Had to start it, run 10 mins, shut off cool down, (about 2seconds!!) then fire up again, again and again, to get the slush to melt out enough to flow!
I remember once when one Detroit 671 did go (with a little too much help from our friend Ether) I thought the crank sheared, the rods were going through the head and the thing was going to detonate and make one big crater! The smoke choked me out for half an hour! And many years later, that machine is still going today. It's a real love hate relationship.
The biggest thing I have found in the PS 6.0, is the 0W40 Rotella T6. Made a world of difference in cranking and starting. I normally keep it plugged in over night. I did fire it up at -35 cold soaked. Once. It was not happy about it. Poor thing. I actually thought that it was the end of that engine. I could not believe that little engine could make those noises! I had 15w40 at the time. You could tell the HPOP (my assumption) was cycling for the first few seconds. From 0 rpm, to 1000 over and over for about 15-20 seconds. And I thought the Detroit could puke out smoke! Im kidding, Not quite that bad, but I really did think it was never going to run right again. I thought it would have scored up the pump walls or cylinder walls or something and that was the end. But everything seems fine. As bad as the rep that engine has, it has been fine since. Good little engine!
