I'm not sure when the switch happened but I think it was late in the 21 model year... either way, early EcoDiesels in the Gladdy came standard with a block heater but the cord was an option. And for the 22 model year they come without a block heater, and it's not even a factory option. I have a 2022.
I live in MN and it gets pretty cold sometimes, plus I like to plug in to come out to a warm vehicle after work, so I ordered the Mopar block heater and did the install this weekend. Anyway, I didn't see a write up so here it is. Pretty straight forward:
Block Heater PN: 56044738AA
There's a Mopar block heater cord with shielding and zip ties it looks like, not sure of the part number for that... I just bought the basic cord from Geno's garage instead for half the price. I also got their plug cover, which you certainly want or the plug's going to end up completely iced over depending on where you put it.
Mopar MS.90032 OAT Coolant, 1 gallon concentrate: 68163848AB
Looking in just behind the shock tower on the passenger side, you can see the block heater plug. If you look in and see a red cap on it, then you already have the block heater. If it looks like it does here, it's just a plug. That unscrews, and your block heater screws in in it's place.
It looks like a 28mm socket would be the right size for removing the plug but I either don't have one or it's clunking around in a frame somewhere. I used a 1-1/8" socket and it worked fine. There's a heat shield directly above the plug that may require a bit of massaging to get the socket over the plug.
Getting to it from the top, or directly beneath, or behind, seemed almost impossible. Getting to it from the front seemed doable, especially if you jacked it up by the frame and drooped the axle for more room. I opted to go straight in from the side with a bunch of extensions. It's a large diameter thread, so it takes a bit of torque to break it loose. Coolant is going to go everywhere, be prepared.
Block heater, comes with teflon tape applied:
I reached back through and threaded the new block heater in using a 15/16" socket.
Installed:
With cord:
Now I don't know the suggested routing for the factory cord, or how they used to route them when they were installed at the factory, but I chose to just run the Geno's cord along the top of the frame rail behind the shock tower, over the sway bar, and into the front bumper where I put a clamp to hold it in place on the backside of the bumper. This also kept it directly away from anything hot. I loosened the fender liner by pulling out the screws and some of the push clips to make the routing easier, but it's not required. And I left the plastic rivets in the trailing edge of the fender liner so I didn't have to mess around with those. If you chose to run it up by the battery, it would be easy to drop the cord down from the top and reach in to plug it in to the block heater without messing with the fender liner at all.
It took just under one gallon of mixed coolant to refill the coolant lost. That's half a gallon of the concentrate mixed with half a gallon of distilled water. Don't use tap water. Alternatively, you can also buy the coolant premixed. Concentrate is more cost effective, however. We'll be installing a block heater in a coworker's ecodiesel as well so one gallon of concentrate was the perfect amount. And, it's always good to have a bit on hand anyway.
Easy peasy.
Total spent: $98
I think I may go a step further and install a power inlet socket somewhere in the front. Maybe in the winch fairlead block off plate until I get around to installing a winch.
