The new one should be r134 compatable, dont stress the conversion involves only changing the O rings which you will have access to anyways since you will have to remove the hoses to change the compresser. Have a shop remove the old refrigerant since it is illegal to release it into the air.
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
r134 should be about 2 lb
First of all, you don't use R12. Rather, R134 which has the oil included.
Yes, it should have R134. Look on the A/C evaporator or on the compressor. it should be listed there.
R134 is used in all cars after 1992 or so.
If you are referring to automotive refrigerant, the answer is no. Neither refrigerant will work properly if mixed and might damage the compressor or other components.
If your vehicle is a 1994 or older is contains R12. 1995-96 It man contain R12 or R134. After 1996 it will contain R134. It is listed on a label near the compressor dryer. Engine size means nothing.
R12 It is not produced anymore. Have to covert to R134.
If the AC compressor is engaging it could be the heater control valve is stuck open. If the AC compressor is NOT engaging you probably have a problem with the controls, a sensor or the compressor.
The 1992 GMC Suburban came from the factory with R12 not R134. Unless it is has been converted to use R134 you cannot simply add R134. If it has been converted you need to have the leak fixed before adding anything. It is illegal to add refrigerant to any system without first repairing the leak. How much it will hold depends on how much leaked out.
Jumped directly from the relay? Bad compressor clutch, bad relay, low or excess refrigerant.
Follow larger hose from air compressor usually by passenger side firewall near accumulator/drier
You do not want to buy Freon as it is very, very, expensive. Have the leak repaired, the system purged of all Freon R12 and the oil. Have it converted over to R134 refrigerant. You cannot just add R134 as the oil used in R12 is not compatible with R134. You will be money ahead by converting it.
The A/C compressor is driven by a belt attached to the engine which runs on gasoline. The A/C unit contains R134 refrigerant which is a gas.
R134 .... IS freon.
After 1992- r134A Before 1992- R22 but it need to be retrofitted for R134 if it hasn't been done already. It is ILLEGAL to use R22 in autos.
No , that should be 134-a ( it should be shown on a sticker just in front of the radiator at the top ) Every vechicle from 95 and on uses R134A. Some cars may have even started converting over to r134 as early as 93 but officially EVERY VEHICLE from 95 and on has r134
read sticker on A/c unit should be there Rick ASE L-1 MAster TransMichigan.com
r134 a r134 a
Should be R134
Low refrigerant charge
Unless it has been converted, prior to 1996 it was Freon R12. After that it is R134, 134a, or a similar refrigrant. Look on the dryer or the compressor for more information.
