So the -40 claim is unverified? Thanks.

5.9L Cummins Grid Heater Delete Information
Information regarding the purpose and operation of the heater grid on the 5.9L and 6.7L Cummins diesel, including the pros and cons of deleting the grid heater in favor of increased performance potential.
www.dieselhub.com
If extra time for the grid to superheat the intake air to 284F is unaided or that diesel antigel for winter is unaided.
Then I guess the heated garage and hot block starts are unaided too?
Those grid heaters are great for killing batteries where it gets cold. Almost 2kW at over 200A for 30 seconds is always a good time.
I am fairly sure you are better off using your block heater, then at least you still have a chance to start when the grid melts its power relay. Or at least extending its life somewhat.

No doubt and I’m glad I will never have to try.
Abuse and Cruelty to diesels!

After -45C cummins really need to get plugged in or you are staying home.
I do not plug mine in unless its -20c. Synthetic oil is worth every penny.

Impressive video. Thanks for showing another reason to love my Cummins diesels.

Its the reason I started loving cummins, a coworker on a pipeline job was starting his at -25C not plugged in….. but no grid heater, he did not realize you had to wait to start, he would just turn the key past. I figured if the engine lasted as long as it did with no special treatment and no repairs, that was the engine to get. Fleet trucks get fleet abuse unfortunately.
We also had another guy trip the Positive Air Shutoff at highway speed. Truck still lives.

While they may well start unaided at those temperatures why be that rough on an engine.
Plug the poor thing in for an hour or two, get the frost out of the block.
The grid heaters and hi pressure common rail systems are good cold weather starters.
My little eco-diesel always amazed me at how good it would start in cold.
Of course the additives and blended fuel that the engines are fed with at those temperatures helps abit also.
But if possible I plugged all my diesels in for cold weather starts, they sound and behave so much better.
Those that don't wish too that's your business just don't tell me it's not needed because it may not be necessary.
