Does anyone else find the length of the block heater cord on the new diesels to be a little short. It does not even stick out of the hood, therefore the hood needs to be open rendering the command start useless. Poor design. My only real complaint so far.
There was a post a few weeks ago where missing block cords and routing was discussed. I have the V8 and its cord is plenty long for me. I like plugging them in outside the hood as there has been more than once I've backed out forgetting to unplug. Makes you look kinda foolish when you trail a yellow snake down the road

Hubby and I have a 2012 V8 GGC. Once we located the cord and un-bundled it we realized that our cord was also too short to be routed outside the front. We had to add a short extension cord and pull it through near the tow hook to be able to use it easily.
I'm glad I saw this. We just got ours and I didn't even want to try starting it since it was 25 below last night. Too bad it doesn't have the right length cord. Maybe I'll add a battery warmer and connect them together before going out the front.
I noticed this morning that even though it was plugged in it struggled a little to start this morning. Granted it was -30 but still it should start relatively easily when plugged in no? I have an 03 cummins that would start even not plugged in.
I don't know where I got this, but I have in the back of my mind that the block heater only runs for 60 minutes then shuts off automatically. Gotta check the book when I'm off work.
The block heater is a simple electric cord leading to a heating element immersed in engine coolant. I am not sure on the JGC, but they are usually installed where a frost plug would go in the engine block. It will heat as long as it is plugged in. I use an external timer on mine to come on in the morning 2 hours before I leave for work.
I have not used the block heater on my new GC yet, but on my previous car you could hear a sound like a kettle of water just before it comes to a boil when the block heater was plugged in. For those of you that use this, if it is quiet enough can you hear a similar sound? If so, it would help to diagnose if the block heater is working or not.
Failing that, a simple continuity test with a multi meter across the two prongs of the plug should tell you if there is a circuit or not. I will check mine and see what the resistance reads as a point of reference for others.
