If its factory R12 have it refilled with R12A as its more efficient, easier on your a/c pump, hoses etc and environ friendly to the atmo than R134A.

Don't confuse R12A with R12.

Its also a LOT cooler and you don't feel the power sap when you turn the a/c on UNLIKE R134A. :(

You'll need to find some one licensed to deal with it; a lot of the people are not so if they try to bag it in order to sell you crappy R134A then go somewhere else.

The bloke I use is on O'Sullivans beach road Lonsdale. Forget the name of the place; he's on the northern side of the road around half way down.

R12A is a tad more expensive even though its basically BBQ gas. :P

Mine cost $138 for a vac and refill with dye. From quotes I received around 120-140 was the going price.

I was told to avoid the R134a with the R32/R33's air con compressor as its not designed and doesn't cope well with the high head pressure of the R134A gas. I remember when I had R134a in mine; it noticeably sapped power and made the aircon compressor audible inside the car.

The R134a is apparently 20% less efficient so it places a greater head demand on the condenser which in turn pushes hotter air through to your radiator and places a greater parasitic load on the motor via the compressor.

Only 'some' places deal with R12A is because in large quantities its highly flammable and apparently requires a license to work/purchase it.

When I first had mine regassed it wasn't that cold... Checked out the aircon evaporator and it was covered in dusty junk that was impossible to remove. Replaced the evap core with a clean one and it was so so cold it would make your bones hurt in your hand when placing it in front of the vent.

It would also make your cheeks very cold to the point where I used to manually turn down the a/c on fan speed 2. :)

Putting the multimeters temp probe in front of the vet I was seeing 0-2degree's. :( Super Icy.

ok heres the facts from a fridgy

R134a A/C systems run a synthetic based oil in the compressor, its in all new cars from '94' onwards

R12 is mineral, running either or in the wrong system WILL do damage to your compressor, which in turn will put more load on the compressor and give you that zap in power

my mate was very disgusted in the R12A is a tad more expensive even though its basically BBQ gas. statement and had this to say about it

R12a if CLAIMED to be LPG, is a timebomb waiting to happen as soon as you get a leak and a spark or point of high heat say a turbo

he said there is about 4-5 replacements for R12 and that he has a chart with all the different options

the one that kept comming to mind was ICEON 39 aka R413a

now further to my research on the R12a because my mate wasnt sure what the 'a' ment he said sound like some kind of blend but had no idea so i told him its somthing i can google and i come up with this

lol the bbq gas statement was not to be taken seriously.. But as you can see (propane/butane) it is partially a bbq gas. :yucky:

The 'if claimed to be bbq gas/disgusted' statement; it doesn't sound like he knows what R12a is??

I spoke to the gas bloke who's a neighbour and deals with R12a before having mine gassed.

He said its definitely not a time bomb in a cars a/c system like many say. The amount of gas within an a/c system he said its not dangerous and is no more dangerous than R134a. It requires a naked flame to ignite as does R134a.

The large amounts used at a workshop yes it is. He said within the industry he has never heard of R12a causing an explosion within a vehicles a/c system.

Also after a little googling it appears R134a is flammable at 720degree's and R12a at 890degree's.

So a lot of people who don't really know make a lot of generalisations. I remember something being mentioned of why R134a has become the gas of new car a/c systems; something to do with the people who make it; politics and being in bed with car manufacturers.

The bloke across the road said not to worry and go with it as its a good thing. :nyaanyaa:

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
