What a coincidence -- I stopped by Big Lots on the way home from my church and bought a couple of cans myself. Much closer than Sam's Club, which is 60 miles away. Big Lots also doesn't have a membership fee. And I was able to buy just a couple of cans versus a full case. What an ideal situation.

Bill is silly. Why is he buying freon by the can when he already owes Brandon something like 5 cases.

Not only is the Big Lots freon more expensive, Bill is also going to need a box to put it in.

Big Lots freon comes in cardboard cases. The cans are not rolling around loose in the back of their warehouse delivery truck.

This morning the price at Sam's club remained $4.50 per can. A Sam's club membership costs $40 per year and can be canceled at any time for a full refund.

Total price for 12 cans of freon at Sam's club, including the $40 membership is $94.

Total price for 12 cans of freon at Big Lots is $96.

Bill claims he has been purchasing freon by the case. You decide which place sells it cheaper.

But doesn't Bill have to travel an additional 60 miles one way (120 mile round-trip) to reach the nearest Sam's Club, while his local Big Lots is literally just down the road? Or is that wrong - I can't keep up with the great freon price war debate :)

Assuming that Bill's vehicle averages 20mpg, and at the current national average of $3.47/gal, a trip to/from Sam's Club would run Bill $20.82 all by itself. Add that to the price of the 12-pack of freon at Sam's, including the $40 membership, or $94, and Bill's true cost for freon from Sam's would be $114.82.

By buying at the sales price at Big Lots, or $81.24 for a 12-pack, Bill is effectively saving himself $33.58, or almost 5 extra cans of Big Lots sale-priced freon for Brandon :)

However, with a Sam's Club membership, you could buy yourself an East Penn manufactured Duracell AGM battery for your DeLorean - a Sam's Club exclusive offering, and from what I've heard at an unbeatable price!

Sam's club freon is still cheaper. I'm still trying to get rid of my cans that I paid between $7 and $12 for. I've been selling them to people at $8 a can just so I can brake even on them.

Although I've got about $300 worth of the stuff, I'm tempted to go buy a $54 case of freon at Sam's club just to show Bill the receipt.

I'm buying a case this weekend because one of the A/C hoses on my school bus was rubbing against a frame member bolt, and yesterday we lost it (much wailing and gnashing of teeth from the kids -- I just sadly watched all my freon evaporate in a big white cloud). The bus takes at least 10 cans, if not 12. Probably should buy a 30 lbs canister, but at $5.40 cans will be competitive enough. At least I won't have to drive to the other side of Fayetteville to buy it.

Big Lots sells LED's?

They have some 12v LED "tubes" that I was thinking of trying for courtesy lighting. At $6 each minus 20%, they might be worth buying. The trick is, they're "blue" -- now, I have never seen blue LEDs, so I am guessing what they have is white LEDs with a blue diffuser. If I can remove that diffuser, then I'll have a good solution. I have to cut off the connectors, since they come with cigarette lighter adapters, which means if they don't work I can't take them back. That's why I've been hesitant to spend money on them so far.

Blue is actually a very common LED element color.

Just buy yourself some white LED strips at Advance or Autozone. You'd only save $1.20 at Big Lots anyway. You need to buy something significant -- like a whole case of freon -- to save big bucks.

I didn't know they carried such things. Do the LED strips come in their own housings? The problem with my previous solution was the LED elements were unprotected, and kept getting hit by people's knees, and so would get turned around or damaged. Eventually one of the fixtures fell out.

dvonk
07-12-2013, 11:45 AM
unfortunately, if they are blue LEDs, then they are probably just that. various compounds in the semiconductors vary what particular wavelength of light an LED emits... in the case of blue LEDs, c. 450-500nm.

have you considered waterproof SMD LED strip lights (http://www.amazon.com/Waterproof-Flexible-Adhesive-Olympic-Lighting/dp/B005EHHLD8/)? theyre cut to length and 12v already... theyre enclosed so the circuits are protected:

i used 5m of the 3258 SMD LED strip lights to illuminate my display cabinet... it turned out really nice. i used the non-waterproof kind because i didnt need that feature indoors. they also make strips using the 5050 SMD LEDs, which are considerably brighter, and also double-density strips that have 600 SMD LEDs instead of 300. colors available as well.

here is my display cabinet as an example, the color temp and light levels are accurately displayed in this photo.

Yeah, I've seen those strips. I used bits of them for my parcel shelf lighting. But that was when I was making a big order from Superbright. If I'm only buying one or two things, I don't like ordering online, because I just really hate paying the shipping charges for little things like lights and fixtures. I always exhaust any local sources first. Plus, at the moment, I'm looking at a July 25 deadline.

Amazon also sells freon by the case. Cost is $76.51 for 12 cans which comes out to $6.38 each and you don't need a coupon or have to pay sales tax. Plus you don't have to spend money on gas since you get free shipping.

Oh wait! I found another seller on Amazon! $58.95 for a case of 12 with free shipping. Cost comes out to $4.92 each and you don't have to pay sales tax. Thats almost as good as $4.50 a can at Sam's club. Beat that Bill!

I can't speak for everyone else but I own three cars, my parents have three, and I've done AC work for three other DeLorean owners in the last twelve months. My car doesn't need more than 2 or 3 cans a year to stay topped off. I'm simply stock piling before they quit making the stuff like they did with R12. Even if I were to pay $15 a can right now it will still be a good investment for when prices rise to $30 a can. I help lots of people and many times I even give stuff away. I'd much rather give away a cheap can of freon than an expensive one.

So it's safe to assume your car leaks oil, hydronic fluid, and coolant too? I mean if its easier to just replenish than it is to repair why bother at all. The difference here though is the R134 is bad for the atmosphere.

... huge amounts of black smoke coming from our vessel.

Heavy diesel particulates (soot). Basically carbon. Stays close to earth (too heavy to go into the upper atmosphere). Causes problems when concentrated, but otherwise is no more harmful than smoke from forest fires, which are estimated to produce 50-75% of the world's airborne carbon.

It's the stuff you can't see that eats away the ozone layer.

I forgot to mention that I have to put one quart of oil in the car every week, my brake master cylinder has a big hole in the side of it which I have patched with duct tape so I still have to top it off, and my water pump leaks too. As long as I keep the fluids topped off the car is fine. As my grandfather used to say, "Oil is cheaper than parts".

Farrar
07-17-2013, 10:39 AM
If you have a leak in your a/c system, repairing it may be as easy as replacing an O-ring. The O-rings are easy to get to on our cars, and they aren't any mysterious or proprietary part -- just go to your local parts house and ask for an O-ring kit for GM air conditioning systems. I got mine at O'Reilly for just a few dollars. It came with more O-rings than I needed, so I ended up throwing some away, but it wasn't much money wasted. Plus it came with multiples of each size, so if I ended up nicking one of them by accident, I had spares.

The biggest investments to work on one's own air conditioning is a good set of gauges and, optionally, a vacuum pump. But you only have to buy those once, and you get back the return on your investment before long.

Um, Steve -- a quart per week *IS* a tad excessive (unless you're driving round trip to Chicago on a daily basis). Are you leaking it or burning it?

Leaking brake master must be the reservoir. Would take a little fabricating, but I can make you a metal manifold to mate to the cylinder with an NPT port that would allow you to attach any kind of home made reservoir you wanted (even a remote reservoir).

Hervey fixed that water pump.

I donated the three cans we charged Brandon's system with.

I have two cases of freon, plus some miscellaneous cans:

- One case for personal consumption

The stuff doesn't go bad. Nevertheless, I will likely exhaust my current supply in less than two years (my fire department buddy, who has neither Big Lots nor Sams Club in the metropolitan DC area, wants me to bring 4 cans to recharge his minivan).

Why are you so concerned about my freon purchases anyway? Care to monitor how much peanut butter I have in my kitchen cupboard, or extra rolls of toilet paper in my bathroom cabinet?

There are several forms of currency that exist in the world today. Beer and cigaretts are two that come to mind but those expire. Refridgerant such as r134a does not go bad. It simply increases in value as time goes by. Ten years ago you could buy cans of r134a at Walmart for $4.50 a can. Today the same product sells for $11 a can at Walmart.

Laugh all you want, but r134a is a more stable investment than the stock market. Have you ever heard of commodity investing?

r134a is still a better investment than toilet paper. When your toilet paper gets wet, you might as well just flush it down the toilet. My cans of r134a are sealed shut. When my cans get wet, I simply ignore the water and the contents inside stay nice and fresh.

Are you sure? Only do this if it's not too much of a PITA. My compressor should be in virtually new condition considering that it hasn't seen hardly any use in the last 32 years, but then again, I honestly have no idea.

Should I get anything other than refrigerant to do the job?

Am I right in assuming that if I get r-12 instead of r-134a that we won't need to drain and replace the oil in the compressor? Or is it still recommended to change the oil in the compressor regardless of what we charge the system with?

What is your opinion of Freeze-12?

What is your opinion of Freeze-12?

My opinion of Freeze 12 is don't waste your time with it. It is just a super expensive r134a hybrid. I'll bring a compressor just in case, but yeah, yours should be fine. Changing out the oil in the compressor takes less than 20 minutes.

You will only need a few things to make this work.

1. 3 cans of r134a. Don't buy the junk that has oil and leak detector in it. Just buy pure r134a.
2. An adapter kit
3. A bottle of ester oil. Don't buy the stuff in a can. It comes in an 8 ounce plastic bottle at AutoZone/Oreilly's for about $8. 7 ounces of it is actual ester oil and one ounce of it is miracle goo.
4. If your local AutoZone rents out AC Vacuums then get one. They are free to rent. If they don't rent them out, I will bring a hose that will let us pull vacuum using engine vacuum.

The whole job will take less than 90 minutes. If you don't like r134a the job is completely reversible contrary to what people will have you think. Ester oil is compatible with r12 and r134a. All you have to do is unscrew an adapter, pull vacuum, and refill with r12 should you want to go back.

This is how I see it. A functional r134a system blow much colder air than a non-functional r12 system.

Oh, and if you want to flush the thing we would need a quart of paint thinner. I won't have an air compressor to do the flush with but we can use the high pressure side of the compressor to do a flush. I'll have to verify with Bill first though.

NightFlyer
07-23-2013, 12:00 AM
Is a flush recommended? If it's not too much trouble, I suppose it would be a good thing to do. I've read that Bill flushes backwards in order to prevent clogging the orifice tube - is that right?

Do I need to replace the accumulator at all or no?

I have a pretty decent DeWalt air compressor:

http://d3spdo3nk3n5ki.cloudfront.net/p600/567379-20121004233151-dewalt-120v-electric-portable-workshop-air-compressor.jpg

Are there any special fittings that I should get?

I can get 12a for $5/can. Would 12a be easier/better than 134a?

I'm assuming that my system is either completely or close to being empty. Whatever I end up getting, I'll just go ahead and get a case of refrigerant just to make sure I have enough, plus then I'll also have extra to use for topping off in the future. :)

I'll check around and see if I can get an A/C Vacuum from somewhere. If not, my neighbor has one and I'm sure he'd let us borrow it.

Greasy DeLorean Mechanic

Your compressor likely will start leaking at the front seal sometime after you put it into service. I got two years out of mine. The shaft spins in a lipped seal, just like a water pump or the crankshaft. I'm sure your's has gotten rusty sitting idle over the years. Start surfing eBay for a replacement now and you'll able to snag a bargain at a leisurely pace.

You need a rubber tipped blow nozzle to interface an air compressor to the low pressure hub. If you use the A/C compressor itself to push the paint thinner through you can only go forward from high to low (reattach the high side hub to the A/C compressor after pouring the paint thinner in and leave the low side hub loose). Use mineral spirits because R12 originally used mineral oil. It's also benign on 30 year old rubber. And ester won't react negatively with any residual.

I recommend conversion fittings sold by NAPA. They are the same price as el Cheapo aluminum adapters, but are made of steel. They also come with their own schrader valve (look closely at el Cheapo's -- they don't have a valve, but rather a spring loaded pin that presses on the original R12 Schrader valve. They are totally wide open on either side of that pin). You have to remove the original R12 schrader valves to use NAPA fittings -- use a pair of small jaw needle nose pliers.

I did #5939's R134 conversion in a friend's driveway 400 miles from home, using the A/C compressor itself to flush the system, and the engine to pull a vacuum. Less optimal than stand alone air compressor and vacuum pump, but it does work. I lived off that conversion just fine for many years until I bought a hot dog compressor (now a belt driven 150 PSI unit on the service truck) and Autozone started renting vacuum pumps. I still flush my system from time to time just to ensure the orifice tube stays clear -- my life long goal is to never replace it (can I get an "Amen" Farrar).

Well, I think I've got you all beat on refrigerant prices - $4.16/can for 12a! :)

If I use 12a, then all I should have to do is evacuate, flush, and refill, right?

I'll start looking for a compressor.

You will need an R12 can tap (Steve's can tap won't work with R12 threads).

You can screw an R134 adapter onto the original schrader valve to attach the vacuum pump (vacuum pumps have had R134 threads for years) and Steve's manifold gauges, then remove the adapter after the system is charged. In this case you would want an el Cheapo adapter without its own schrader valve.

Keep in mind if R12 doesn't work you wasted $100. If r134a doesn't work you wasted $24 to $45 depending on where you get the stuff. $8 everyday price at Big Lots and $15 at Autozone.

I'm against using expensive R12 in leaking systems simply because of cost. And should you ever need insurance work done on your car, good luck finding a shop that will even touch R12. I found out several years ago that those big shops won't even do a conversion because they don't have the equipment to properly evacuate R12.

Agreed - not looking to do anything with R-12.

But 12a is just as cheap, if not cheaper than R-134a, and they say it works better than R-134a in R-12 designed systems such as ours. The 12a is basically a mixture of propane and butane.

http://en.wikipedia.org/wiki/HC-12a

I can get it for $4.99/can delivered if bought by the case (12 cans).

I'm pretty sure that the cans are set up for a R-134a tap (if not, could someone let me know):

Do you really want to fill your system with a product that warns "Very Flammable Tres Inflammable"?

Bet that would be exciting when your condensor is damaged during a front end collision (remember: the condensor sits above and in front of even the over rated crumple extension).

Just use R134, says a man who will soon be burning it 30 hours to/from Louisiana -- it works just fine.

they say it works better than R-134a in R-12 designed systems such as ours.

Walk into almost any store that sells r134a and you will see cans of stuff bragging about some sort of miracle goo that will make your ac colder. Its simply bull. My favorite false advertising company is Artic Freeze.

Pure r134a or pure r12 is your best bet. According to the experts, there is a 10% difference in vent temperature. I get 44F vent temps with r134a. This means I should expect 39.6F temps if I were to run R12.

My system leaks about one can a year. I would much rather top it off with a cheaper alternative that is almost as good. 44F is pretty dang cold to me.

If there is a Sam's club close by I would gladly go in and buy the stuff for you. Or you can get it at Big Lots for $8 or even cheaper if on sale.

If there isn't any of those places close by, you can get a case of it from Amazon pretty cheap. The link is somewhere in this thread.

I believe the first picture will work. Walk into NAPA and tell them you need r134a adapters for an old GM car. Take a picture of your existing fittings (with caps removed) and show it to them. They will know what you need.

I bought a high pressure adapter from them about a year ago and still haven't gotten around to installing it. I beleive I paid $5 for it.

Are the R-134a service fittings not needed?

I'm guessing that you have a hose with an R-134a can tap and R-12 service fitting connectors - is that right?

I've never done A/C work in my life, so I'm slowly but surely learning :)

r134a fittings will be needed. All of my tools are for r134a.

Basically you just need to buy the chemicals and fittings. If NAPA doesn't have the fittings let me know and I'll bring a set for you along with all the tools I will be carrying.

OK, I'll take a look at the fittings on there and get some R-134a ones from Napa sometime next week and get them all swapped over before your arrival. I'll also make sure that none of the bolts that hold the compressor on are seized.

I'll probably go to Sam's Club this Thursday to pickup some R-134a. Other than making sure it's pure refrigerant (no additives like stop leak or oil) is there a particular brand that you recommend that I should be looking for?

Thanks again for all the help :cool:

r134a is r134a. They are all the same as long as you purchase the pure stuff with no additives.

Just get your hands on some NAPA fittings if you can but don't install them. The schrader valves need to be removed before they are installed and we must "properly evacuate" your system if there is anything in it. You don't want to go removing shrader valves while there is pressure in the system.

We can take care of all that stuff when I arrive. It wouldn't hurt to make sure the four bolts that hold the compressor to the engine aren't seized though.

When I leave, you will having working AC.

After battling 5 o clock traffic in Atlanta, he has finally passed into Alabama. During his drive through Atlanta he had the AC blower set on speed 3 but it got so dang cold that he had to lower it down to speed 1. Bill said r134a is more than cold enough for him.

Cool beans! Glad to hear that Bill is enjoying Atlanta rush hour traffic (I've done that a few times myself). :)

BTW - It wasn't that I was concerned about coldness, I just thought that using a hydrocarbon refrigerant like 12a might have made for an easier / less involved conversion vs R-134a.

After we get my system going again, my passengers will no longer be able to say that riding in my car is like being in a stainless steel oven :p

I bought a 30 lb tank also online. Can't remember what I paid but it was way cheaper than buying by the cans. It saves you from needing to put the cans in hot water since that big tank does not cool down like a can does.

http://www.ruralking.com/r134-r134a-refrigerant-30-lb-cylinder-6330.html

Assuming comparison to the standard 4oz freon cans, this is equivalent to 120 of them. Assuming you can snag the 4oz cans for 5 bucks, that is 1.20 per oz. Whereas this cylinder comes in at 16 cents.

Its also nice, you don't have any waste, and a guage manifold fits right up.

Here in Australia it is no longer available and you need a licence to use R134A, you must have a recovery system if you de gas any refrigerant. Thats I suppose Australia's contribution to reducing the hole in the ozone layer. It probably matters here as we are one of the closest country to be affected. We have even banned Halon extinguishers expect for use in aircraft. It been like that for nearly 20 years.
