Gen IV Block Heater installation guide?

If there are any and you find one that makes it any easier to install on your model, count yourself in with the other lucky people that actually found the mounting hole in the block.

Another easier way to battle winter temps ( if you have a way to monitor coolant temps ) is grille block. I use large soft pipe insulation for the big grille opening and the regular pipe insulation for the smaller grille openings cut and trimmed to fit.
I also use the car scanner app to monitor the coolant temp,

 

I've some gen 3 info, one link in my signature*, for what it's worth. I've done an install on our 2010, and it was a bear, getting all the adjacent conduits, bracket and what-have-you, disconnected and shifted sufficiently to get the damn thing outside the hole and perpendicular to it to go in. And yeah, fourth gen, with the battery in the engine bay, is even more crowded.

Paramount tip: don't apply the heat grease till you've managed to get it in. Then back it almost out, reach the grease in on a finger tip, apply it lberally, use it all, then work it back in, twisting, keeping it perpendicular, trying not to scrape it off too much.

Attach the wiring clip beforehand as well.

* on a phone turn it landscape to see signatures.

 

I can't remember if I removed the wipers and cowl (again, on our gen 3). That might help, with doing from above. I suspect I didn't though. From above I unbolted some brackets, used cords and whatever to pull everything away as much as possible. Then raised the front end, and removed the underpanel, did the install from below. I still needed to practically pry something with all my strength, to gain a few mm clearance.

It's one thing to have the block heater element ensconced in it's hole, but before that can happen it also needs to be outside of the hole, another 4~5 inches back. And that's nigh impossible. Lying under there, basically going by feel, with an arm on both sides of the drive shaft, scraping edges with your knuckles and arms, applying dabs heat transfer grease (once you've got it in once, then pulled it back out). So much fun...
