I haven’t had time to see if high idle is set but I did find out the remote start won’t work if the heater is plugged up. Guess to keep from burning it out maybe

Did you have the hood cracked open to get the cord hooked up?

If so, that's why the remote start won't work.

(should work plugged in, if you feed the cord out somewhere else so the hood can be latched)

Does anyone have an idea what temperature the block heater will maintain the engine coolant at? And can anyone confirm or not if there is an ambient temp thermostat to limit the block heater from functioning above a certain air temp?

I work shifts, and after a night shift I like my truck to be warm quickly. I just keep it plugged in. After last nights shift, average air temps was low 40s all night. ECT was 83 degrees after 6 hours on heater. So I am pretty confident it was not heating, as that is normally (+/- 5 degrees) the temp of the ect after a shift and not plugged in. Breakers not popped, and power to plug is good. A coworkers cummins seems to maintain the ECT at 130 degrees after being plugged in. I will see after 12 hours tonight if it is any warmer. Just wanted to ask if anyone monitors the ect after being plugged in.

Never mind. After a little more research on the forums, and some tracing on the truck I found my heater element. Using the heat gun, I found the brass nut on my heater to be roughly 134 degrees F, after 5 hours of being plugged in. So i will monitor ect over the next few months. I guess the duramax just doesnt maintain as high of a temp as the cummins. I will continue to remote start, and enjoy warm seats when I get in. Maybe I will look into adding a oil pan heater, help lower those 120 pound oil pressures on start up.

Just your wallet, but unless your seeing frequent temps below 0*F you don't need to.

These trucks are not like some of the older hard to start mechanical injection pump systems were.


It will start easily and happily at least down to 0*F.

Remote start and elevated idle are your friends.
