Why I Never Plug The Truck In During Winter

I have a large engine for the type of work I do. Rarely does it even break a sweat. I would imagine that is the reason. The engine temp never goes over 200, and in winter it struggles to get there in the mornings. Detroit engines typically run cooler than the others from what I hear.
Also remember that we are in the prairies, so hills are an anomaly in this part of the world. One one run I do there is one hill, but if I take a different route to that same destination, the river crossing is a higher bridge, so no hill.
If I was pulling a fully loaded super B I would be worried if the fan didnt come on up a hill!

 

Once my truck warms up from the ambient temp of 0F or colder it never sways from its 200 on the gauge. I dont see any problem there. As far as I can tell, if there are changes, then I should worry. But as long as things remain the same, then its OK.

Correction to my original post... its a Detroit, not a Cummins. Sorry for the confusion.

 

I dunno...I think that 200 degrees is rather high and I don't even know much about the engines yet, lol. When you think of the boiling point of water is 212, and you're running at 200...thats pretty close. Granted, I don't know the makeup of anti-freeze and its boiling point, if its the same or not...but just as a comparison...200 is high. Considering that I run around 150ish and thats in western WY and Eastern UT where we have some hills. I run a Detroit 60.

Id be concerned if I was hitting 200 on the plains.

 

no that was perticularily bad winter. You may remember it out your way. Cattle were freezing to death in the trailers, my dad had a set of batteries freeze up driving down the road. There was a 60mph head wind out of the west and I was running flat out barely able to maintain 50mph. It was an eye opening situation for a near rookie driver.

 

I remember using old railroad track switch heaters, we used to slide them under the pans to thin things up, I still have some of thoes heaters in the shed i wonder if they are worth anything, I know the small RR in the quincy shipyard still uses thees heaters on their switches, But now I just program the APU to start up if the outside temp reaches 31 degrees, it senses the temp, starts itself heats the coolant and powers the block heater, charges the batteries, and heats the sleeper, it also has a 3000 watt inverter, Yes I am spoiled, and earned it, heck I didnt even ask for it, it was all just handed to me with the truck,, Sometimes I miss owning my own stuff and sometimes I don't

 

I appreciate the concern. Thanks for the input.
