Delux Harrison Heater W/Defrost

I love this thread.  I lucked across a Chevy Deluxe heater maybe a year ago and have a couple old normal Harrisons here.  I will definitely follow your lead and swap the core and backplate.  Not sure how I want to get the defrost plumbing onto the windshield yet.

Yes it is a lot of project creep. As you can see though in the photos I am missing my trans/transfer combo. So there is a lot of stuff going on. I am working on that combo, working on the clutch, the flywheel,the starter, throttle linkage, wiring issues, front lunchbox install, new seals and gaskets, steering box issue, all on top of a heater refresh. I am slow and take time researching how to do stuff because I am not a mechanic. I don't remember how I took stuff a part/ so I work on the stuff I can to keep things going. My jeep hasn't been on the road since July of 2020 and I really want to get it on the road for this spring. I wish I knew some locals that I could incentivize with beer and food to give me a hand lol. 

You mean my little half tank? Well it came that way when I purchased the jeep. As far as I can tell it had extended at one time under the passenger seat. There is evidence of a tank strap setup on the passenger side , it would also account for the tool box being missing. I am guessing the owner before me might ave taken it out and cut and welded the connector tube. It has a rear tank that holds 15 gals. It also has external fuel pumps for the fitech efi system. The rear tank is a sore spot with me at the moment that I need to address as well. When I fill the tank I need to fill it as slow as possible because for some reason if you fill at a normal speed it will over flow gas all over the place not from the fill hole but from underneath. It flows out all over the rear axle and the ground. I haven’t looked into it at all yet but will have to when I get it all back together. I am not sure if it is vented oddly or not at all or if there is some hose not clamped. But I hadn’t drive to this in so long I forgot about this issue until you asked about the tanks lol. Ugh there is always something.

I finally was able to get some painting done on my jeep. I need to tape off all the sharp edges and some of the areas that might rub trying to install the heater. Then after it is all plumbed I can start on the wiring. I have a question, How does one fill the heater with fluid properly when hooking it up?

Okay that's easy enough! Thank you.

Well it has been a long time and I am completely done with this project. I was able to buy a 12volt to 6volt reducer on Amazon that was good for 30 amps. I hooked it up and now the heater works as it should. I was able to also hook up the defrost in my cab.

This is a video of the working heater.

Nice work.  I have one of these in reasonably decent condition that I need to restore as well.
