02 Grand Caravan EX leaked freon. I have A/C guage. My vehicle does not have the sticker any more due to an accident. I need to know the proper amount of freon and what both guages should show to verify everything is good. I have performed a full vacuum of the system and verified that there are no more leaks after replacing a defective high side service port which leaked everything out.

 

2.88 lbs of freon, usually about 2 oz of pag oil. The low side should be below 35 psi and above 20 psi when the compressor is engaged. the high side should be below 400 psi.

 

Thank you. Much appreciated.
