It has been so hot lately, I decided to see how easily my 300D would start without the use of the glow plugs. So one afternoon when it was in the mid nineties, I started it cranking right away without letting the glow plugs run. It ran 8 cycles, that is Ra-da-da-da, Ra-da-da-da . . . fire-up. I am assuming that every Ra or da is one turn of the starter. Maybe not, but it is my unit of measure. Then this morning when it was about 70 or so, it took 16 cycles. They seem to count off in 4s.

I am in Pennsylvania. This heat is nothing compared to Texas. So I am wondering, at 110 degrees or so, which it has been down there for some time, how quickly does your diesel start without using the glow plugs?

And, is there any harm in starting without using the glow plugs, assuming I have a good battery?
