Default Engine coolant heater question

Another question from a new duramax owner. The cord to plug for the engine coolant heater (engine block heater? same thing??) is short and right now I am draping the cord over the edge of the body under the hood in one of those notches on the inside of the body panel. This means I have to open the hood everytime I want to plug the heater in. This is a 2006 Silverado LB7 engine. My old '96 Sierra 6.5 just had the cord hanging down in front and I accessed it through the left front wheel well. Is there a way of threading the cord down into the right front wheel well a way that won't damage anything and I don't have to open the hood?

A little careful routing should get it to the tow hook, or under/over the bumper in the area. I do not recommend having it hanging in the wheel well area.

Dmax, it seems like the cord is fairly short. It seems like it's only a couple feet long! I'll just have to wait for a warmer, sunny day and see if I can try your suggestion.

Put Rotella 5W40 oil in it and forget about the plug. I think I've plugged mine in twice in 4 years...

It's long enough. Barely.

Do you have a spot where you can put this?

Mine used to just make it over the grill/under the hood - would hang out about 3 inches. The constant moving around of the cord end caused the wires inside to fail, which why I went with the permanent install.

Where 'bouts in Eastern PA are you?

I wrestled with that idiotic, too-short cord until I finally realized it was simply too short and no amount of jury-rigging was going to fix that.

So... I bought a 4-foot long heavy duty extension cord and gave the factory cord the length it should have had right from day one.

I secured the business end of the xtension cord behind the right front bumper (up out of the way as much as possible from road garbage... snaked the cord upwards and plugged the heater cord in.

Everything is secured so nothing rubs or vibrates.

So far, so good.

Last time I checked, you could buy replacement block heater cords at most auto parts stores. They plug in at both ends, so installing a replacement (perhaps longer) cord is possible...

The cord is plenty long:
