Where to go to have A/C vacuumed and refilled
Replacing condenser/dryer this week (doing it myself). System has no refrigerant as it all leaked out.
Just wondering, I assume simply getting a couple cans of "freon" and refilling won't be enough. I guess it'd need to have the whole process redone.
Dumb question but, any chains someone could recommend after doing a DIY fix? Looking at either Aamco, Firestone, the Nissan Dealer, or Midas. Only because I'm out of town and want to be able to return to any store in case I need to.

Take the plunge.... A cheap vacuum pump and gauge set from Amazon will do the job.
My advice would be before you start or head out to the shop would be to remove the compressor and drain the oil. You don't know how much oil is left in the system.
A pump, pump oil, compressor oil, gauge set, and 2 cans of 134 from Walmart would be under $200.

You can use Duracool instead of Freon. You need less Duracool than R134 by mass and it's easier on the engine, but cools the same. I use Duracool in all of my vehicles. It is compatible with R134 and can be mixed with it for topping up. The best part is you do not need oil when using Duracool. Its molecule is also much larger so it is not so prone to escaping through microscopic cracks.

So far 2 duds in this process, the drier from Amazon and the valves from advance. Atleast the condenser though looks much better.
I'd love to do the home kit but I'm already burnt out on buying stuff. Started changing hoses, fuel filter, and now EGR valve will be next process.

There is an A/C Schrader valve tool that I bought at Advance. I buy the valve kit that has two large and two small valves with caps at Advance. Throw away the small valves and use the large ones. Make sure the new valve springs are good before installation. I've found a new valve with a broken spring before.

The OEM high side cap fit the aftermarket one but not the low side. I'm considering just returning and either going to the dealer (for the part) or just have wherever I get it serviced at to remove it. I don't know why they didn't have the caps with the valve. Just unnecessary frustration.
But for the record...the housing of the valve actually comes off the pipe? Looks like it's welded in there. Don't want to break it...trying to keep this whole DIY on the low as I know once they know you worked on it, they blame you if anything goes wrong.

You need one of these....
A regular valve remover is too small or short rather to work.
Any auto place will have them. You just need to get one that is long enough to reach down and grab it. The valve just threads in like a bolt.

This whole drier trip is becoming a crock of crap. Between removing the battery to get it off, and the stubborn connector, and the o-rings. Now I'm just wishing I'd of just left it on...but it is original and the system is open.
I order a replacement because the one I ordered before on Amazon was the wrong one..,even though it said thru 2/97 (mine was made in February). Then I go to advance, they give me one that looks right, but the connections are off. It's supposed to look like Mickey Mouse but instead it's next to each other. Several tries to fit it didn't work, the a/c hoses aren't the slightest bit flexible.
Unless they gave me the wrong one, I'm about to either find a store that has a Denso one or go to the dealer. Screw these crappy aftermarket a/c parts

There was a mid year ac change in 97. The new one is for after the switch. Get one for a 95-96. I believe the compressor changed as well as the condenser.
The other thing to check is the fitting from the compressor to your new condenser. The hose fitting to the condenser is a different size.

Well that one for the 91 q45 is similar but I think the older r12 one was larger. Tried that one as well before this and it didn't match up.
But FINALLY got my a/c done. ****ing ridiculous. The shops down here wanted $125, couldn't really find many specials. Ended up coming across a Groupon sale for $59. Well they come back to say the area around the drier was leaking. So ended up having to pay them an extra $60 to put O-rings On. I put the ones that came with the new drier but some reason they weren't sealing up. That's after I had to get them to drop it down a little from $70/hr...
I hate **** like that. Then they give the whole "don't do it yourself" lecture on air conditioning. I try not to argue too much but it's irritating when you think you did something right and it then have to pay extra money to have them re-do it. Usually only have that problem with doing a/c. But why would I want to pay someone $400/500 to fix a condenser/drier which is only held on with 4/5 bolts?
But I think some places penalize you for DIY stuff. And the costs to evac and recharge an a/c system is crazy considering it an older car and the possibility of leaks again. But for the most part they said that everything held up and the a/c has been really cold.
