Did the 1994 and 1995 Geo Trackers with the 1.6 use r-12 or 134-a for the a/c units?Hope you can give me an answer.Thanks

well i couldnt tell you I removed my a/c unit and there is not tag in my engine compartment. but if it was r 12 then it would be best to find a kit to convert it to r 134a its a lot cheaper and saver anyways. if you can find r12 it will be very expensive to buy.

R134A

Look to see what type of connectors the AC lines have on them for hooking the guages up.  If they are threaded, then it should be R12.  If they are the snap coupler type, then it should be R134a.

Here in Canada you can't buy R12 anymore. You can only use R134A - if your system is R12 it has to be retrofitted to R134A.

Here in the US, they would like you to think you can't buy R12 anymore.  It is still readily available, but they have restricted its sale to people that are licensed to buy it (which isn't hard or expensive to get....last I checked).

A long time ago, my mechanic told me a story that environment-wise, there's no damn difference. That the only reason they made the switch was because  the patent expired for R12, and the industrial giant that owned it (DuPont? Don't remember) used its lobbying muscle to bring in 134, which they ALSO own.

In other words, R12 would still have been sold, without the company getting the patent royalties. Whereas they get money for every ounce of 134 being used, whether they manufacture it or not.

Anyone ever hear this? Or SOMETHING like this?

I wouldn't doubt it was either a money issue, or the greenies throwing a fit about it.  Thing is, why can't they use the same propellants in R12 that are used in R134a today, that supposedly don't damage the ozone?

Some interesting reading at the following EPA site....
http://www.epa.gov/Ozone/title6/608/sales/sales.html#q2

Here is a cut and paste from it.....
The following people can only buy refrigerant found suitable for use in a motor vehicle air conditioner (for example, R-12, R-406A, R-414A, R-414B, etc.), including "small cans" containing less than 20 pounds of R-12:

    * technicians certified to service motor vehicle air-conditioners
      (MVACs) by a Section 609 EPA-certified testing organization
    * persons who buy refrigerant only for the purpose of resale to Section
      609 certified technicians, such persons must provide written
      documentation (that includes the purchaser's name and address) to the
      seller stating that the refrigerant is only intended for resale.

So it would appear anyone can still buy R12.  The only restriction is, unless you are 609 certified, you can not use it, but you can buy it to resell.
