If you need info on R-12 HI/Lo A/c pressure gauges, you should take veh. to pro. Once you connect lines from gauges to A/C, you need to understand what the readings mean. avg. lowside @idle = 28-34, avg. Hiside = 120-130.
BE CAREFUL. MANY BEGINNERS and cert. mechanics have made mistakes and injured themselves.

What kind of freon does a 1990 old delta 98 use?
Check the ports to add freon--the low side is a large hose --the high pressure is the small line--on the large line if the valve is the large style----the freon is R134--if the valve is the small style it is R12--no longer used --retro valves are available to convert R12 systems to R134 R12 fittings can't be connected to R134 gauges, and vice versa. If it's R12 you won't be able to connect the hose from the supply can to fill it, or do anything else with R134 equipment.

How do you know if r12 freon is in vehicle?
If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.

What freon does a 1986 MAZDA B2000 use?
It has the old R12 refrigerant.If it is low the R12 is not available anymore.However a product like freeze 12 will work with it.I could go on but,short if you do not have manifold gauges the old style for the R12 fittings you can convert the system over to the new R134 and a shop need to do this simply to remove the old refrigerant and add the new screw on fittings and charge up the system.Sorry for the long over answer,just forwarning you if the AC is not cold and what your next steps should be.
