I believe what you are asking is where do you charge an ac system with 134. I have a 90 Buick lesabre limited and the charge port is located on the accumulator. It is a big silver canister that the refrigerant lines go to. You should see a charging port on the right of it if you are looking at it from the front of the car. I dont know what year your car is so hope this helps you.
r 134
FIRST IS IT R12 OR 134.
R-12 Convert it !! R-134
From factory R-12 Should be converted to R-134
Factory R-12 Should be conveted to R-134
R-134, cars built '93 and prior used R12. However bear in mind that '93 vehicles were a mixed bag of both, some used R12, others R134, and your car could be a '93. One more thing, AC stuff should really be left to the profesionals, not the home mechanic.
Most likely R-134. Just check your fittings. The R-12 fittings won't accept R-134 connection hoses and vice versa. R-12 are screw on schrader type while R-134 are larger.
Most US vehicles before 1994 were R12, so the car will need to be retrofitted.
134 = 134
The address of the Laurelton is: 134-26 225Th Street, Laurelton, 11413 2094
5% of 134= 5% * 134= 0.05 * 134= 6.7
95% of 134 = 95% * 134 = 0.95 * 134 = 127.3
