i have a khyber with sanden 505 ac setup..
recently i got its ac gas refilled with R-12 gas cuz i didnt use AC in winters at all and the old gas went out..that was my bad..
ok,i went to the ac shop with 1KG tin can of r-12 gas..i thought it might be enough for two recharges but whole one kg gas was poured.. plus the ac tech guy said its compressor is weak and you better should replace it cuz car was showin high head pressure ,around 60 which should be 25-30.. coolin of car is not very good but acceptable cuz front two persons can live without sweating now my questions are
1-how to check how much gas should go in? ive replaced evaporator coil last year but there wasnt ant sticker on it about how much gas can it hold..so any way i can check if gas is up to the mark or not? ive seen the glass on drier and it has liquid,but i cant differentiate it if it is all liquid revolving or some bubbles too..
2- if,lets say compressor is weak,which one should i go for? i am not lookin for original one as i dont have that idle money on hand,so success compressor is ok??? where to find original success compressor in rawalpindi/islamabad????? and any approx price?
PS..if some one can show pix of drier glass with low gas and full gas condition,i'd really appreciate it and also many like me would too
peace!
