The EPA states that the "procedures required for a least-cost retrofit are simple and do not require major component changes. Generally, the process calls for the removal of the oil refrigerant, installation of new fittings and a new label and the addition of either a polyalkylene glycol (PAG) or polyol ester (POE or ester) lubricant as well as the R134a refrigerant"... EPA
There are many retrofit kits on the market you can get from an auto parts store like Autozone or Advance and even at discount stores like Wal-mart. ID and Quest are two brands on the market that have closed retrofit kits available.
R12, if still available at your local parts store (requires a license), is very expensive. It is cheaper to retrofit the system to use r134a.
anything 94 and below is going to be r12, unless someone has put a retrofit kit on there then it could be r134a. some people have been know to put other dangerous things in there freon. r12 freon is really expensive. the best thing to do is go to local auto parts store and buy a r12 to r134a retrofit kit and have the system retrofitted
It's only Freon if it was manufactured by DuPont, but to the important things... Your 89 would have had an R12 system from the factory. You can't use R134a in an R12 system unless you do at least a partial retrofit (evacuate all the R12 and compressor oil, replace the orifice tube, replace the accumulator, replace the hose connections, add PAG oil and R134a).
R134a is all that is available If you have an R12 system You have to retrofit to R134a I didn't go through the hassle of changing the entire system to r134a I just recharged the system with the new freon and it's working just fine. The coolant even last longer.
i belive its r12 ... but just get a retrofit kit so u can make it a r134a
An R12 system must be retrofitted to be made compatible with R-134a.
Originally it would have had r12. It could have been swapped over to r134a. The high and low service ports will tell you what you have. Small threaded service ports are r12. Larger quick connect/disconnect service ports are r134a. You should also be mindful that not all R12 to R134a conversions were done as a complete retrofit, and often a simpler method of replacing connectors, the orifice, and accumulator would be done, which would leave the original R12 schrader valves, in spite of it now being an R134a system. If in doubt, it never hurts to err on the side of caution and have a shop do a refrigerant purity test.
R134a
It was built with R12, can be coverted to R134aIt was built with R12, can be coverted to R134a
It was built with r12. It can be retrofitted to R134a.It was built with r12. It can be retrofitted to R134a.
Was built with R12, can be retrofitted ot R134a.Was built with R12, can be retrofitted ot R134a.
no u can not mix the 2 togather it wil ruin the hvac system
