When I stuck this cummins in my chevy I didn't put the grid heater back on. I thought " I'm in Arizona, Who needs a grid heater". Elk hunting up by Flagstaff this year saw temps around 10 degrees. I was real worried the truck wouldn't start. No problems. Started up quick, shook for about 20 sec and we were down the road. This Cummins is great.
