When do you diesel people plug in?

Since most of my front engine stuff is new in my truck lol,( I'm sure Roy still has a twitch over it), I'm fairly confident she will start semi cold weather.



It was 2 degrees outside today and she barely had any smoke out of the exhaust when it fired up.



LOL but I know that's a false Security in my head, I still have not yet installed my block heater, but have it in hand but how cold would it be before diesel does not start, or I guess a heck of a time to fire up?



I know I just have to remove a frost plug but knowing my lucky, I'm expecting something chaotic to happen once punch goes in that frost plug.hehe

I’m ok till -10 for a reasonably good start, but I plug in at 0 Monk. The truck likes it much better

Wait for the cool weather. You should have no issues at -10.
