what does it take to put ac in?

[chris142]

It turned the compressor on and off using pressures...pressure =temperature

Ahh, that makes sense

 

[SPR1NK]

Is there anything I need to know as far as recharging the system once I get it in my truck?
Needs to be converted to R134a correct?

I would change the receiver drier and TXV while you're at it. Will have to be vacuumed down for quite a while before you recharge it.

What is all that?

Vacuumed down?

 

[chris142]

You use a vacuum pump to remove the air and moisture in the system before you charge it with refrigerant. The txv is also called an orifice tube.it meters the refrigerant as it enters the evaporator. When converting from r12 to r134a you want a txv that's approximately 15%smaller than the r12 one you removed

Where do I get all of that stuff?

Is it absolutely necessary to do that?
My dad didn't change any of that out on the Lincoln, just used the cheapo retrofit kit on it and it works fine, or is that bad to do?

At this point, I would recommend you purchase an AC manual. I have the Haynes AC manual no. 10425. I think I purchased it at O'Reilly's. Even though the manual is a bit "generic", it will help you understand automotive AC and help you understand what it will take to get the system repaired and recharged. Reading the manual will help you decide if you want to just swap in the parts and then have a shop vacuum the system and recharge it for you, or help you decide if you want to invest (or borrow) some special AC tools and do the whole project.

He got lucky. Do some reading and studying. I put ac in my ,91. The wiring and plugs will be there once you get it all in.

 

[SPR1NK]

Ok

So then where do I get the receiver dryer and txv things?

 

[SPR1NK]

On the vacuuming the system thing I am curious

In my old Toyota one of the ac lines had a big hole in it, so I patched it with a combination of rescue tape and jb weld and recharged it, and it worked, did I get monstrously lucky? Was it super dangerous doing that?
Just curious, can't say how long it would've kept working in that truck, I wrecked it a week after doing that, but it does have cold air during that week lol

Autoparts store. Or online, google Automotive Air Conditioning.

 

[SPR1NK]

Ok, thank you

Is there a certain make/model of those I need to get?
Or that like a personal preference type thing?

 

[SPR1NK]

So the receiver dryer looks like a little can with an inlet and outlet?

I'm trying to look it up online

I feel like I'm being a giant pain sorry

Gut the parts truck, bring about 200 for parts, drive to Portland. We will put it in, go home in chilly comfort.
