This is a heads up from Carbon Car Systems Blacktown; not just to anyone in Sydney but Australia-wide.

After the 1st of July, the W/s cost of air cond gasses will be going north by anything up to 600%.

If you were thinking of holding off until summer to regas your system, think again!

So, previously, what was it, $70-100?

$600 to regas?

Portable aircon and an inverter would be less.

Can then also remove the aircon system, weight saving bonus.

Any reason Terry?

Govt making it harder due to hazzard?

The gas used by Skylines (and many other cars) is "R134A"

So when current stock of that is used up by your supplier Simon, the cost of a regas at the moment which might be say $95 will go up to around $150.

The breakdown of the above, is part labour - part gas cost.

There will be a different substitute refrigerant available in late 2013.

Cost to be advised...

Story's been on the news.

The Carbox Tax genius' have worked out it takes "X" tons of Co2 to make a Kg of refrigerant gas, so the gas industry has to pay.

Guess who picks up that tag.

Yeah...

Do you have any idea about the next new refrigerant yet "G", in regard to....

a) cost?

b) efficiency?

I received some word that it was going to be less efficient than R134A, but that's just heresay.

I'm out of touch with these new gases Terry, but next time I'm dead keen to try Hychill in the 32's older system.

Trouble seems to be finding a fridge tech. out in the sticks who's willing to give it a try.

However I can remember when R22 and R12 got shafted. Exposed commercial freezer units had their gas stolen and sold black market style.

I'm certain these crazy gas prices will start this practice all over again.

Ah thanks for clarification Terry.

Can anyone explain why we need to regas a closed system?

There's plenty of potential refrigerant leaks in any car's aircon system.

First off would be the shaft seal at the compresor. It's a carbon/carbon seal plus a conventional fla seal but over time it's going to leak.

This is why you're asked to run the aircon for a short time every day, to keep the carbon seal lubed and happy.

The seal has to hold static gas pressure (approx 75psi) when the syetem is at rest and then down into vacuum when the system is loaded.

Next are the flexible hoses at the compressor. They're swaged over a hose barb but any gas will still leak slightly.

And finally the gas will permeate through the actual hose material over time.

All removable connections are flare metal/metal or "O" ring and are very trouble free.

The compressor in your domestic fridge is inside a sealed unit, there's no flex/rubber hose and all pipe connections are silver soldered.

The refrigerant in one of those will be there until something mechanical fails.

Hi Guys,

After the 30th of June 2012 I would presume any refrigerant that is CO2 depleting will go up in price I would presume. This is because of the Carbon Tax.

I would also presume a lot of other industries that are emissions heavy will also be charging more for their services such as Transport etc.

Kind Regards,

Daniel

Thanks for the info.

I was never told to run it every day.

I will now though.

So are there any other gases we can use in aircon/refrigerator systems?

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
