If the system is completely empty then it would take 37 ounces if the truck has a single unit and 62 ounces if it has dual units...........
R134a
R-134a
The Freon capacity for a 1997 Pontiac Trans Sport with dual AC is 46 ounces of R134a refrigerant. The capacity for the same vehicle with single AC is 32 ounces.
There are two types of air conditioning types found in the 1997 Chevrolet Suburban. The front only ac systems have a Freon capacity of 36 ounces, while the front and rear ac systems have a capacity of 64 ounces.
Personal posession of freon is illegal in the US. Unfortunately, you are required to take it to a shop.
The refrigerant charge amount and type should be located on a tag under the hood of your vehicle. I believe that around 1996 auto makers started using R-134a instead of the R-12 refrigerant used prior to 1996. Check your tag mentioned or your compressor may have information on it.
The same as you would with a single a/c system, charged on the low side service port. If you connect a small can of Freon to the high side with the system on, the can may explode from the high pressure introduced into it.....
Contains no Freon. Freon was banned beginning in 1996.
2lbs. Should be on label top of accumulator
You can put Freon into your 1997 Nissan Pathfinder from the low pressure port. Connect the Freon bottle to the port. Release the Freon into the air conditioning system.
where do I add freon to my air conditioning unit on a 1997 chevy truck?
Freon is R12. Your 1997 Chevy uses R134 Refrigerant.
