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.
Your 1990 has R12 refrigerant in it which isn't available anymore at parts stores. To add refrigerant to your vehicle you will have to get the a/c system vaccuumed and retrofitted to accept new r134a refrigerant and pag100 compressor oil. You can take it to a shop to get it vaccuumed and retrofit it yourself with kits from your local Autozone. -broncomudder89
Can you tell us what year it is. It could be needing R-12 (then you would need to do a retrofit to the R-134a.) You can also look it up on the website linked below and it can tell you what refrigerant and what type of oil and how much of each your system needs. Look on the tab for "locate your low side port" following the instructions to the Refrigerant & Lube Spec.
That would take R-12. although r-12 is very pricey nowadays. R-134a is much cheaper, but if would need a full retrofit
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.

A retrofit kit is just like a normal kit which has list of component's/ parts to assist the particular retrofit process.
It is easier to build accessibility into the design rather than having to retrofit a solution. He tried to retrofit a fuel injection system into his old Mercedes. The retrofit using new lenses effectively repaired the Hubble Telescope.
The 1991 Acura Legend likely uses R-12 freon refrigerant in its air conditioning system, as it was a common refrigerant at that time. However, R-12 has been phased out due to its environmental impact, so it may have been replaced with a more environmentally friendly refrigerant like R-134a during a retrofit. Check with a professional mechanic to confirm the type of refrigerant in your particular vehicle.
This means to install or substitute new parts that were not available when the machine was made or created. Here are some sentences.They will retrofit that airplane with the latest safety equipment.They looked into an energy-saving retrofit program for the business.They will retrofit the factory to meet the new specifications.
If you mean changing from R-12 freon to R-134, you don't. R-134 uses a different kind of oil and if you put that oil into your present A/C system it will eat through the seals, destroying the pump and everything. Sorry. I really dont think that is the case. Retrofit kits are available to convert to r134 and new O rings are part of it. Compressor oil is compressor oil, just because the refrigerant is different does not mean the oil is. The new refrigerant actually has poorer cooling abilities than r12 but is better for the environment.
