Have you ever tried to find the plugin for you GMC Sierra’s engine block heater? If so, I’m sure you were as frustrated as me when I went looking for mine!
The designers at GM must have thought it was a great idea to put the plugin where they did. Seems to make sense in some ways. It’s relatively easy to get to, as long as you know where to look.
Where you ask? Well, on my 2001, the plugin is located in the front driver’s side wheel well near the front, behind the tire. It’s probably easier to get to it if you turn your wheels to the left first. On the 2001 there is a plastic piece that is between the wheel and the engine. Down near the frame you should be able to see the cord of the block heater. It might be coiled up or it might be sandwiched like a letter S over and over (there is Christmas candy that looks like this, like a ribbon).
Now my only problem is trying to figure out where to feed that cable out through. Once I detach the cord, it’s going to drag so it can’t stay in the wheel well. Guess I’ll have to fish it up through the engine compartment and out through the grill or something like that.
When I figure out the easiest way, I’ll add more to this entry. ;)
Please feel free to add comments about other models and where you can find their plugins.
One thing you can do is have it come out underneath the grill. There’s a gap in between the bottom of the grill and the top of the bumper that is large enough to fit the plug through. You’ll probably have to take the plug cover off to do it because it kept getting caught.
The other option (if you have front tow hooks like me) is to pull the plug through and attach it to the tow hook on the driver’s side. It’s probably easier to do that since you don’t really need to fish the plug up through the engine to get to the grill. Of course, it’s a lot lower down so it’s sort of personal preference where you’d like to plug into. ;)
