How much fluid do i need in A/C
 

refilling compressor again,,,anyone know how much oil and freon these 12a might hold.........thanks.....

I've been looking for oil capacity for two years. Don't know. Best thing to do is measure how much you take out, replace that much plus maybe a couple more ounces. I have a much larger than stock condensor, mine takes about 2.5 cans of 134a. You should need less than that. Watch the high side pressure and the sight glass on the drier (which should be replaced anytime you open the system). For R12, at 95° ambient you should have about 225 psi. R134a should be about 250 to 275. This is with the AC on max, high fan speed, both doors open. Under no circumstances should you see more than 300 psi. Hope this helps.

thanks for the response, the hose blew so i really dont know how much oil was in there,,,

Same thing happened to me... Since all the A/C's in our cars were dealer or otherwise installed, some dumb ass routed a hose right under the Hot start motor bracket. Years of vibration cut a nice chunk outta the hose.

Oh well, just forget it,,,3 lbs and still no cold air just cool,,,but what the hey, its a sports car,,,and i need to here the road......
