Block heater cord

[railguy777]

I have a 2020 SLT with a block heater. There is no thermostat in the cord. It must be in the block heater itself. I checked the cord with and ohmmeter and it always conducts. Plugged my heater in when it was -15 C and no current draw. The other day it was -21 C and the current draw was 3.5 amps. So the thermostat must be set somewhere around -20 C.

Just a cord hack I want to pass along.  I am the kind of person that would forget to remove the cord and drive away with it in.  I went to amazon and got two key chains that have a red cloth tag that says "Remove before flight" in big letters.  I put one on the cord and have another with a large carabiner on it.  When I plug the truck in I put the tag with the carabiner on the steering wheel to remind me the cord is in.  Just passing this along.

My wife has done this twice now. Now i actually wrap the cord around the driver side mirror and lay it on the hood before connecting it. This way it can’t be missed before getting in and driving away. I do like the tag idea though!

My 2021 Suburban, I'm scratching my head as to why I have to get down on my hands-and-knees, sometimes with a flashlight, just to plug this stupid cord into the bumper.  Is there a work-around, other than attaching some 3rd party contraption to the grille?
