The '97 3.1L its rouhgly 30oz.

Hook up A/C refrigerant to the suction side; be careful to not add to much. You can buy a guage and R134 freon at wal-mart or pep boys for cheap but you can't buy R-12 if the system is still R-12 you should consider retrofitting to R134.

Gooc luck.

How do I convert from r12 to 134a cooling refrigerant in a 1992 Buick Lesabre?

I think you can still find the old R12 at a premium price. It would be worth it if your air con system holds well with no significant leaks. Genuine 12 Refrigerant LARGE SIZE 2 14 oz Cans
The old refrigerant and oil are not compatible with the new stuff. The expansion valve is questionable, may or may not work properly. The oil in the compressor, in the evaporator, in the condensor, and in the accumulator/filter/dryer need be removed thuroughly. New service port adapters are installed. Then the new R134 can be introduced. You may find a conversion kit with instructions.
I recall a bulletin calling for replacing the oil and reusing the refrigerant, repeatedly, 2-3X, the final oil replacement gets the new refrigerant.
When ever the system is exposed to the atmosphere, it should be evacuated before refilling. So much to think about and consider.

How do I figure out what type of refrigerant I need for the ac?

The car originally had R12. If it has not been converted to R134 you would need to have it serviced by a pro or have someone convert it to R134. The R134 fill kit will not fit the R12 fittings.

How to recharge recharge airconditioner

Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle. Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power. Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can. Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood. Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care

Where do i put r134 in my 1999 chevy luminia

You have to locate the Low Pressure line for your AC and connect the refill hose and gauge to that. It will have, in most cases, a black or blue dust cover cap made of plastic on it. The refill kit will only fit the low pressure side as these connectors are different in size.

AC does not work

Check the fuse for the A/C and try refilling the A/C with R134. You can buy the re charge kit at Auto Zone or Wal Mart, almost any Auto parts store. If the system is low on R134 the A/C compressor will not activate to keep it from burning out.
Try checking the fuse first then re charge the system with a can 12oz of R134. Just keep in mind not to over charge the system. Just follow the instruction and you'll be fine.
Keep me posted, be glad to help out.

AC is not working

Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
