I did the other day... one of the front lines. Just crack it and let it seep. Make sure you don't inhale it and it's open space.
If you want to buy a set of gauges you can connect them and then SLOWLY crack the valve open on the gauges, but honestly its about the same cracking a line. It will woosh out really loud and scare you if you arent prepared for it. BTW if you do buy gauges (Harbor Freight $40) then go ahead and buy a vacuum pump ($20ish HF) and then get a couple cans of R134a ($10 each Walmart) and you can charge it yourself. There isnt that much to it especially after watching a few youtube videos on it. Part 1. How to properly charge an auto AC R134a refrigerant air conditioning system. - YouTube

So I would connect the red gauge to high, blue to low, and yellow to the vacuum pump. Then vacuum it down and attach the yellow to the cans and put in my 1.8 ish lbs? How do I add oil? I may as well do it myself since its turned into a money pit anyway.
Is that pretty well correct or should I connect them and open either the high or low gauge to bleed it?
Does anyone have a vacuum pump or a set of gauges I could borrow?

You add oil the same way, it comes in a separate can or you can by it pee mixed with one of the r134a cans. I have all the stuff in Decatur if there is no one closer to you that can lend in out.

Oh yeah. Just start the vac pump and open the high and low side to pull a vac on the system. Give it 10-15 minutes pulling vac and then close the yellow line up check the gauges to see where they are at and walk away for 30 Minutes. If your gauges don't move you know you don't have a leak in your system. Now your ready to charge it. Hook the freon up start the car up turn on the AC to max and pump in the cans.

I think I'm following you. Since there is freon and oil in the system, where does what is left over go? Maybe a dumb question, but when I crack the lines most will spill out. But what's left when I put the compressor back on and pull a vacuum, where will the rest go? Into the vacuum pump or what?
I'll start my HF ads and see what it will cost me to do all this. Then I'll call around Monday and see how much it would be around town. Bamapaul, I may hit you up for help and drive up that way if you don't mind.

A vacuum pump at HF that is pneumatic 2.5 cfm is over $100. A gauge set is $50. So even with 20% off I'm in $120 plus freon which would be $36. So it's worth it to install myself then take somewhere to evac and charge the system unless someone in Birmingham has the stuff.
I hope the warranty covers the $168 for the shot compressors labor. I feel like it should. I'm waiting to hear on the labor still. If that's covered then my whole hearted recommendation. At the least the compressor is covered and I've confirmed that.
This would be funny if it wasn't one thing after the next.

I remember the great MR Lewis restored a MARO back in the day...I'd say he experienced many of these things as that thing was a gem when he finished it.
Part of the journey Brotha. Chin up and press on man.
I'll mail you my gauge if you want.

This is the vacuum pump I have from there, as long as you have an air compressor it works great and it $16. Vacuum Pump - AC Vacuum Pump w/ R134A & R12 Connectors
To answer your other question the remainder of the gas is vented off when the vacuum pump purges the system.

Yea. I'm going to stick with it but it has a way of beating you back every so often. And that 69 was a gem. We still have the 78 he had.
I appreciate the encouragement. I'm going to make it happen if only because I refuse to give up.

I guess I'll do that and buy and air compressor. I need one anyway and I'll get it from Wally World or HF. They're like $60.
Thanks. I didn't realize I could get that adapter and attach it to a compressor. That makes more sense than a vacuum pump. Thanks tons man.
I appreciate everyone's help. I'd be lost without the guidance. And I'm starting to see it all come together in my mind for what I need and how to make it happen.

The vacuum pump from harbor freight requires 4.2 cfm at 90 psi and it takes a high dollar air compressor to get that much cfm. I've been doing my research all afternoon and a 3 gal 100 psi air compressor won't cut it to draw a proper vacuum it looks like. Any ideas or commentary on that? If the consensus is that the small pancake compressor that moves .6 cfm will work then I'll do it. If not then there's no point wasting my time.
So I guess I'll evac the system myself then remove the compressor and install the new one unless someone says a small compressor and the HF fitting will actually work to draw a proper vacuum and get everything out before I recharge myself.
I also read on the forums that the liquid refrigerant you get from an auto parts store can hydrolock a compressor. Does anyone know anything about this?

So what did you end up doing? Hopefully you get it worked out before august hits us. Did that guy buy your tundra? You don't need a high dollar compressor hf has a 2.5hp x 21 gallon that you can get on sale or with a coupon for $159 I think or something close to that. It is by no means an 80 gallon but it gets the job done and in half the space and is easier to move. Sorry this might be a little choppy and all over the place I just wrote it as it popped in the ole noodle.
I've got a 60 gal compressor that'll more than move that CFM. You're welcome to come over and help drink some beer and use the compressor if you want.

The new compressor and drier shipped out yesterday. Nobody bought the Tundra yet. Some guy wanted me to drive to Greenville, AL so he could look at it and I had to politely tell him no. I'm going to HF today to price parts and make a decision. I'll let you know what I end up doing.

I may take you up on that. I really don't want to drop a couple hundred on a compressor right now since I'm pretty far in anyway. I may buy the gauges and vacuum tool then borrow one unless I can find a shop to evac the system and recharge for around $60. I'm going to start calling today and pricing and go to HF and price and make a decision.
If you want to, shoot me a PM and we can figure something out.
