So since I have the brass plug on my 22, I can buy (68523853AA) and the bmi cord ?

Anyone tried a Webasto or Phillips & Themro electric heater/recirculation pump?

Thanks to everyone who contributed to this thread. I just ordered part #68523853AA (block heater) and #68535072AA (cord). Are there any tips or tricks for the installation?

If you got the block heater that replaces the brass plug. The cord is separate.

Yup, I ordered both parts. I figured I better get ready for next winter.

Does anyone have a wiring diagram for the block heater? The OE cord has built-in clamps for the cord to attach to something, but I'm not sure what it attaches to. If I could see a diagram that would help.

The cord just plugs into the back of the block heater. The clamps hold the cord to the heater. Far as i know for routing the cable from the block heater to the front. I never have seen a diagram. I did find 2 clips that was unused in that area that I used for routing.

That was the easy part.

The clamps hold the cord to the heater.

There were a variety of clamps on my cord, but none on the first 18" inches of the cord that came off the block heater.

For the most part, I ran the cord close to the inside frame rail and exited on the outside of the rail where the wiring for the fog light is. Eventually, I'm going to drill a hole into the bumper and install a NOCO receptacle.

First off, thank you all for contributing this information as there isn't a whole lot out there with regards to EcoDiesel block heater install info.

I wanted to ask any of you that have experience with the plug-in style connector (P/N: 68523853AA) a few questions, as this forum has the most information I've found on the block heater install (Thank you). For reference, I've got a 2022 Ram EcoDiesel.

I received my heater (P/N: 68523853AA) and cord (P/N: 68537567AA) today and went in for what I thought would be a quick install. I first just wanted to op-check the device before installing just to check it out (maybe this was dumb....as you'll see).

I plugged it in and within 15 seconds or so it started to lightly smoke. I immediately unplugged it, let it cool and then wiped it off as I thought maybe it was just burning off some excess lube from the manufacturer or something, so I plugged it in again and let it sit for maybe 45 seconds to a minute. To my surprise, the solid end of the plug looked like it was starting to change shape and maybe soften so I unplugged it and picked it up with plyers. When I did so, they actually dug into it like it was warm butter.

Now, If this is as simple as "that wouldn't have happened if it was installed as designed and it could have dissipated the heat in the brass plug" or something along those lines, I'm all for the feedback, and will just order a new part and try again....maybe.

It just seems pretty wild to me that it got that hot, that quick, and I'm just supposed to shove that into my block and leave it plugged up.

Does anybody have any long term use feedback for this part? I also saw from reading this thread that the cord for this specific unit is called out by some folks as the following (P/N: 68535072AA). I can't tell if it is actually any different since websites just show a wiring diagram. Seems like the cord is just a cord but again, I melted mine so I could be wrong.

Thanks for all the information up to this point! I'll try and post some pictures later of the deformed heating element. The material almost seems like the same consistency as lead but I'm not sure.

Thanks to everyone here for this info. Had some issues after a -2F, and someone in this forum recommended getting a block heater. Thanks to this thread, I discovered today that my September 2020 build already has one. I can see the faded red cap on it from the passenger wheel well. Now I just need to grab the cord.

A little Christmas present from Mopar and the good folks here. Thanks, and Merry Christmas to all.

I'm not directly familiar with that style of block heater but they're designed to be submerged into a fluid or in this case at least installed into a block. Regardless of how it's installed, you're testing it by removing the medium it's designed to heat. So where is that heat going to go? Air is actually a great insulator and doesn't pull heat away as well as a fluid or another solid.

Think of it like this: An aluminum pan placed in a fire will melt. You can add the same aluminum pan into the same fire full of water and the water will boil and the pan won't melt. (to an extent.) You can even fill a rubber balloon with water and heat it directly with a flame and the balloon won't pop because the water inside is so efficient at wicking away the heat.

It's a little more complicated than that. Boiling water isn't getting any hotter bevtits going through a phase change to gas. Steam is hotter than boiling water and you can continue to heat steam past the boiling point until the next phase change to plasma.

I'm well aware of that, didn't seem necessary to get into those weeds for my example. That's why I typed "to an extent." Heating water to a boil is just a situation everybody is familiar with and easy to visualize.

100°f coolant in a block isn't anywhere near boiling anyway and you're still shedding heat out of the block at a rapid rate if it's cold enough to need the heater in the first place.

My point stands about plugging the heater in when exposed to nothing but atmosphere. Coolant wicks away the heat vs backfeeding into the plug
