Volvo Repair: 03 S60 AC recharge, ac recharge, ac system

Question
I have a '03 2.5 S60 that cycles the AC ompressor every 10-15 seconds. How hard is it to recharge if the freon is low. I bought a combo oil, leak detector 134 freon can. How much would be needed and which side does it get filled on?

Answer
you cant use those cans to fix it the  right way you need to vacum the ac system with ac mashine  and than charge with correct freon  amount only  and than add oil and dye  best is for you go to volvo delaer  or local mechanic dont try using that it will cost you more money later to fix
