| wen i was off driving the otha day i hit a skippy and broke my grill and headlight. i was a bit pissd but got ova it fairly easily. then the worst thing hapend. that skippy had pushed my air con pipe in at the front of the car, and had split letting all the gas out. took it down to one aircon place and they said theyd have to replace all this shiznik and it was gonna cost a fortune. took it to another air con place yesterday and they said that they would replace a cuple of orings and re gas it :). i will be extremely hapy once i can push a button and get cool!! easier than winding a window down hey ;) sori for the life stori but the moral of the story is just shop around!!!. |

It depends entirely on the gas used in it. AND...you can find out which gas is in it by looking at the sticker with it written on it. I think you'll find that they WILL be running a CFC based refrigerant...
I can't remember where the sticker is, but check the side of the a/c compressor. Find out the gas used (it will typically be either R12 or R13a). Then you need to talk to the a/c shop you want to have do the work, and get a quote. |

They are simply different gasses, and for the system to be re-gassed if it is an OLD one, you need to have some fairly fancy arse equipment in your workshop to be able to extract and capture all the old (CFC based) gas. It also costs a bit to dispose of the CFC based gas. If it's a non-CFC based gas then it's a lot easier and cheaper to re-gas a system...that's about all it comes down to.
I couldn't say for sure if the system differs from one gas to the next, I can't see why it would, they are both refrigerant gasses, the same principles apply to them. |

| They fazed out a certain type of gas to my understanding, maybe it wasnt ozone friendly, dunno really, but they replace the old gas with the new type so it costs more than a standard re gas. |

Speaking of Air con......I pushed the little AC button for the first time since purchasing the car yesterday and was very happy when the cool cool air started pumping out the vents :)
Pretty sure from past experience that if the air con is the old type using CFC based gas that there is a little more to it than just refilling with a different gas type. Although it probably should be that easy I believe that there is some componentry that needs replacing/modifying as well. |

Just on the topic of the A/C gas(sorry i know this is an old post but it has to be said). Just about all Pre 1995 A/C systems run on the CFC(chlouroflourocarbon) gas known as R12. After 1995 it was made compulsery for car manufacturers to use the Ozone friendly R134a. Now this means that the mighty old VN's use the naughty R12 gas.
To convert the VN's to R134a the system needs to be retrofitted to be able to cope with the 134a. If anyone tells you different they dont deserve to be in the A/C business. Most will tell you that all that needs to be changed is the TX valve(or Thermal eXpansion valve) this is not recommended or legal. The hoses used in the R12 system are not able to handle the 134a gas because the 134a has a smaller molecular structure. The hoses used in the 134a system have a neoprene(or silican i am not 100% on that) lining making them able to handle the gas.
Now things that should be replaced when retrofitting are as follows - Hoses, TX valve, reciever dryer, all system o-rings, accumulator, oil and orifice tube. Also it is highly recommended that the system is completely flushed as the oil used with R12 is not compatable with R134a.
A good A/C fitter should be able to advise you on the right way to do the retrofit.
Good luck.

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

| If you've got all the required pumps, and capture equipment and you're licenced to handle CFC gasses, then you can do it legally. Otherwise, you'll get seriously fuc&ed up in court if you get caught. EPA would bend you over and spank you hardcore for it. |

Have a look at the epa site. It seems the original work on molecule size has been reconsidered based on oil absorption. also the condenser performance etc is also not as affected as originally thought. I searched this as one garage wanted $350 to change lots and another said not needed and wanted $135 to regas. anyway this is a cut and paste
When R-134a was first introduced, it was thought that all non-barrier/nitrile hoses would have to be replaced during an a/c retrofit. Early laboratory tests showed that the small R-134a molecules leaked through the walls of non-barrier hoses more readily than the larger R-12 molecules did. In the lab, this caused unacceptably high leakage rates. More recent testing, however, has shown that oil used in automotive a/c systems is absorbed into the hose to create a natural barrier to R-134a permeation. In most cases, the R-12 system hoses will perform well, provided they are in good condition. Cracked or damaged hoses should always be replaced with barrier hoses. |

Interesting stuff there. Have you got a link to the EPA page that's got the rest of the info on it? Be good to have a look at the rest of it.
