A/C delete question
Hey guys,
I'm going to delete my A/C. It doesn't work and I like driving with the windows down anyway. If I remove the pretty much everything up the box on the firewall will I still retain my heat? What about defrost?

Re: A/C delete question
Yes. You'll have to close up the existing box where all the A/C components hook up. The cleanest way would be to either find a non-A/C car and take use it for parts or buy an A/C delete box so that you don't have extra junk sitting in your engine bay.

Re: A/C delete question
There's two reasons I did not use a AC-Delete pulley.
The more I looked at the pulley the less I liked it. For me it looked totally out of place
Then it started to eat my belt.
So I put the compressor back on for what I thought would be temporary fix.
I left it on because at least it looks like it belongs there.
(the engine in the first photo needed cleaning)

Re: A/C delete question
See how Ron removed stuff? That's what your's should look like, good reference photo, Ron.
Yeah, I personally wouldn't care for the random no-use pulley either, if it works fine just spinning the compressor then cool, i didn't know (I have a V-belt set up).

Re: A/C delete question
Thanks for the pictures guys. They help a lot.
When you say I need to close up the box where the A/C lines hook up too does that just mean I need to plug the lines?

Re: A/C delete question
If you do not want to spend the money for an a/c delete box you could cut off the line connections in the heater box and then cover the slot where the lines came out of with aluminum. I used opened up soda cans and then mounted my coil to the front of the box. It looked ok but was still kind of bulky. Like previously mentioned, an a/c delete box is the best way. They are not really that expensive, there is one in the classifieds for $100 shipped.

Re: A/C delete question
Hey Ron, i was debating on pulling my AC pulley in favor of a delete pulley but after reading your thread im kinda scared!!! How hard was it to remove what you removed? That looks really nice.... freed up alot of space on passenger side !

Re: A/C delete question
Though if you go the A/C delete box route you'll have alot more room, here's mine for reference (I have the A/C delete box). It really cleans up the whole area there.

Re: A/C delete question
I had Lingenfelters do my ac delete. And I have never had a prob....
they got all the parts from gm. The bracket and pully come assembled. there are two black washers one in the front of the pully. And one in back...you must have them in place for it to work....or you will eat belts...

Re: A/C delete question
I deleted the non working ac on my 86 T/A. The compressor and lines were already off the car when I got it. I wanted to clean up the firewall and give my car a cleaner engine bay. I took out the large heater case out that bolts to the firewall under the hood.
I found one in a junkyard off a non ac car. I pulled it off, cleaned it off and installed on my car. Think the junkyard charged like $15. It bolts directly in place of the large ac unit.
Looks like Redleader289's picture.
Just be careful pulling the old one off. Most of the bolts are accessed from out side the car on the firewall, but there are 2 bolts on the bottom that go through the inside, so you have to fold back the carpet on the passenger side floor to take those out.

Re: A/C delete question
One last question. I know I don't want Freon leaking in my garage. How do I know which pipes have Freon in them?

Re: A/C delete question
I took mine to a shop that charged me $20.00 and hooked it up to a fairly impressive machine that took about five minutes to do,
If it takes 5 minutes for the machine then you're in for a surprise if you crack open a line or play around with the system in any way. Just call around and get a decent price and take it in.

Re: A/C delete question
Just call any shop and ask them if they have an AC recharge machine. They vacuum out the lines with it and puts the r134a or r12 back into containers that are hooked up to it and the machine uses that stuff when charging anyones system, You have a valve on the high and low pressure lines with Caps screwed on, IF you open them and hit the valves with a screwdriver, Hold your breath and if there is more than 2-3 seconds of pressure then you need to take it somewhere, Most of the time they will leak out after a year or two of not being used, But not always

Re: A/C delete question
If you have any worries about refrigerant, I too would recommend taking it to a shop. Midas, Firestone, etc will all be able to evacuate it for you. It shouldn't cost much for labor, as all they do is hook up two lines and turn on their machine.
Refrigerant is dangerous. If it hits your eye, it freezes your cornea. Causing non-repairable blindness. There is a lot more refrigerant inside the system than you think. Probably something along the lines of 1.5 lbs worth. That's a lot of refrigerant.

Re: A/C delete question
If your AC doesn't work your Prob. already low on Freon. Take a screw driver and press down on the shrader valve slow and see if ya get a HISS outa it. If you do it still has SOME charge. If you dont Then your fine to pull the lines,etc.. ( freon isnt that great for the ozone, or if you breath a TON of it. Its not gonna hurt YOU to take a screw driver and release it. Just dont breath a ton of it in)
If its still under pressure then you do have some AC charge left. Could be a few ounces could be a full charge and something else wrong with the system.
Do you know whats wrong with it?
As for having a shop do it.. DONT let a shop charge you. If you have R12 still in the system They will reuse it. Same with 134a. We charge $22/lb at my shop for an A/C recharge + Labor. I'd never Charge someone who stopped in to just recycle the system because they wanted to remove everything. I'm the one making out on the deal. Even if its only a few Ounces or 2 lbs.
Yes they will take about 5min or so to evacuate your system. The machine used will recycle the freon. Now they have the extra to use on another car.
The cleanest way is to remove it all and put back in a Non-Ac heater box.

Re: A/C delete question
^what he said^
Do the test first, because there's a good chance it'll be empty or very low. Didn't mean to scare you, it's just like anything else when working with chemicals and things that aren't meant to be breathed/drank/eaten/etc...be careful, and you'll be fine.

Re: A/C delete question
Finally got to do this job this evening. I ended up not having to go to a shop to get my freon evacuated/discharged. I checked pressure at the schrader valve and nothing came out so i dared forward. Rest assured i went in ready. Jeans, long sleeve shirt, mechanics gloves and had my ski mask & snow boarding goggles on lol. I unbolted the bolt behind the pulley and not a single drip/fume came out.
