1990 Geo Metro Q&A

1990 Geo Metro Question: Air Conditioner Low pressure point

I just bought my Geo Metro 2 days ago. I would like to add Freon to the Air Conditioning system. The instructions suggest inserting it at the low pressure end on the system. I see 2 insertion points. One is near the pasenger cab the other is near the air condtioning fan. Any one know which one is the low pressure point ? -
Answer 1
first of all, why are you doing this?? it is dangerous stuff that can hurt you if you do something wrong. the system needs an exact amount to perform correctly. you cannot tell how much is in it or how much it need. take it to a shop to make sre of your concern. by the way, the fitting will only fit on one port. they are different sizes.
