Hey All,

I'm trying to remove my AC system as it's leaking fluid on my floorboard and I want to get that fixed prior to fixing the rust in the floor board. See radiator fluid on the floor board in the pic.


Any suggestions on how to get this big ole box out from the cab? I've got the hoses undone and the compressor removed, but I'm not sure what other bolts I need to removed. I've circled two bolts that I've removed in the engine bay as I figured out those were holding the system up.

I've also removed the circled bolts from in the cab, but I'm not sure if there are any further bolts holding the AC system/box in place.


Any and all suggestions are welcome.

 

1968/72 F100/350: This is factory installed integral A/C that is combined with the heater, the A/C controls are in the same panel as the heater controls (see pic below).

 

Thanks NumberDummy! I hope I can find all the bolts and other connections in this pic.

 

If it's anti-freeze, there was no need to remove the compressor or lines. 99.9% chance the inlet or outlet tubes in the heater core are leaking. Been there/done that to many times. It's basically a feel all around to locate the screws holding the front case (18754?) on. Air inlet (18A586) needs to be un-clamped. Glove box in the dash and glove box door need to be removed to access the top of the front case. I wanna say 19C853 & 18C855 brackets need to come off as well. It's been to many years since I had mine out...
I do know I'm going to remove my entire unit and replace it with a modern after market one that's way less prone to failure & uses newer refrigerant but same factory controls. Like here.. Worth every penny IMHO!
Three heater core replacements in 5 years due to inlet/outlet failures is/was enough. Swear words & cut/sliced fingers a-plenty. But I had the replacement time down to about 2~2.5 hours.

***Don't lose that 18A586 or the gaskets if you're planning on keeping the factory unit, there's no replacement that I ever found. And be sure to throw down some soaker rags on the floor board when removing the old core. Ask me how I know..

THANKS for that LINK, Yeah, that After Market A/C is definitely on my list. I would really like to know if it will keep the cab cool in a 100 degree weather. Anybody out there have one of the Classic Air systems??

 

The unit heats & cools. I have zero doubts it'll out perform the factory unit and take up a lot less room. Although I'm NOT a fan of the way they plumbed it by going into/through the fender well. One loose tread on a tire, mud build up, etc. etc. and the plumbing is wiped out. I'd redo the plumbing to go through the firewall only.

I would like to get some pictures of how those AC lines run from the front to the cab.

 

If you're wanting the after market heat/ac routing from the link I provided, you're going to have to grab the file here. It's to large to upload. It's the pdf file @ the bottom of the page. Tad over 5 meg..

Factory AC Not mine but mines almost identical

 

I used to have a cab with that unit. Remove the glovebox liner(very shallow version) and make sure all brackets/bolts are off. I can't recall all the mounting points. "IF" you want, you can replace the heater core in that original model. You have to completely dismantle it from the front to get to the core in the back. As me, I know. You would think they would put an access panel in the back? Nope.

Or you can buy an aftermarket unit and replace the whole thing? I've used Vintage air in a couple of project vehicles with good success. You can reuse your old York compressor style if you want to keep the look. They make conversion plates to retrofit the newer small Sanden compressors. The kits are not hard to install.

 

Thanks for all the info guys! I now have the unit completely out. I did cut two of the AC lines as I figure they can remake them. Hope I didn't screw the pooch on that one.

 

Also, I'm thinking of selling this to go to a vintage air system. fan squeals and it's leaking. Anyone interested,if So, PM me.

 

I would not try to reuse the old lines.

 

I thought your system was a vintage system you must mean upgrade to an aftermarket system.

 

aftermarket system by vintage air. I’m thinking of doing something similar to what I saw someone else do by using one of their different controls in the spot of the ashtray and fabricating in a double din stereo slot. This will be a resto mod when I’m done. Will be starting my build thread here soon I hope. Gotta clean out the garage for a spot the truck will fit into first, then it’ll be disassembled and modded.
