Block Heater

[redwngr]

Check the rpo code sticker in the glove box to see if the truck is equipped with K05.

 

All owners manuals are the same, the don't print separate ones for each combination of options.

Also you can see if the heater is screwed into one of the core plugs on the drivers side

Sorry to bring up an old topic like this, but my owners manual states I have a block heater and the cord is wrapped up in the wiring harness and cover that is taped up on the right side next to the fuse box under the hood.

Here is my dilema, yes there is a harness there, yes it is big, yes it has a ton of vinyl tape around where it T's off, etc, but unless I know 100% sure there is a block heater cord there, I do not want to start un-wrapping the harness.

 

From reading on this older topic I know before I do try to un-wrap stuff, I will look in the glove box for K05 code posted by

Also I will read on my sticker which I have to see if it came with one, but I do remember it stating I had the SLT premium plus package, and Z71 off road package, 6.2L engine, but that is about all I remember on it.

Now is that a good location to start looking if I have the K05 code or would it be mounted somewhere else on a 2017 6.2L?

Mine is a 2017 Chevy ltz, not a gmc but my cord is on the driver's side fender near the front, and you can see the cord and plug end. It's not in some taped up harness.... Not sure if that helps you?

Mines a 6.2 also....

For the Diesels they are on the Passenger side, underneath the coolant reservoir. Sounds like the gassers are on the drivers side.

Thank ya sir yes that does help now I am not worried about the harness, I did not get time last night to look for it, but I will tonight for sure.

Oh man never thought of that just trying to find that darn cord if it is there. LOL
