Air Conditioning '90 SE

[lovemonkeysd]

Does anyone know the air condition system capacity for a '90 SE (R-12 refrigerant) and what pressure it's supposed to be?

If I need to convert to R-134, could someone post procedures and problems if they've converted?

Thanks!

Hi,if you like to refill your system with R12 you need 1,4 kilo of it and the right oil for that.
If you like to change to R134 you have to remove the compressor and clean it inside.You also have to change the Dryer.The reason for that ist that R12 only works well with mineralic oil.R134 only works with syntethic oil.
Before you do that check your air condition for leaks.
And your system loosing every year 8-10% of refrigerant.That`s normal.
