Same thing
There are 16 ounces to a pound. Doesn't matter if it's one pound of dirt or one pound of bricks.
The weight of one gallon of R134a refrigerant, also known as norflurane, is 4.5713 kilograms. This is equal to 4,571.3 grams or 10 pounds 1.25 ounces.
All r134a low pressure (suction) connections are the same size. All high pressure connections are the same size. The low and high connections do not interchange.
easy first by pass it with a wire link next fix leak and recharge with r134a 800grms at suction pressure of 200kpa remove wire link and re connect on to Lp switch

All of your charging to your ac system is done through your low side port. The low side service port is located in the line that runs from the compressor through the evaporator (firewall) and up the condensor on the low pressure (suction) side of the system. R134a recharge hoses will only fit on the low side service port on all R134a vehicles and R-12 vehicles that have been converted to R134a.
The make and model doesn't matter - the correct pressures for an R134a system in one vehicle is the same as the other. What the pressures are supposed to read can vary greatly. There's a little something called the 'pressure/temperature' relationship. In short, the ambient air temperature and humidity level are going to impact what the correct system pressure should be. So, depending on what the ambient air temperature and humidity level is, the correct operating pressure can be anywhere from 28 - 60 psig on the low side, and anywhere from 130 - 350 psig on the high side.
R134a goes into the low pressure port
YOU WILL NEED TO FLUSH THE SYSTEM TO REMOVE THE OLD OIL. ALSO INSTALL A HIGH PRESSURE SWITCH AS REQUIRED BY THE EPA. THEN INSTALL CORRECT AMOUNT OF OIL COMPATIBLE WITH R134A. CHARGE TO ABOUT 80% OF R12 BY WEIGHT.
Density of R-134a changes with respect to temperature and pressure.
You should just let the system take the refrigerant out of the can by itself. It is not good to force liquid r134a into the low pressure side of the ac. The suction of the compressor will draw the r134 out by itself and stabilize the system as it goes, it may just take longer than you want.
Look at the suction connector if it is a screw (threaded ) connectorit will be R-12....if it is a quick disconnect connector it is the newgas as of about 1994 R134A.

IT'S EITHER ON THE ACCUMULATOR OR THE LINE THAT GOES TO IT.THE ACCUMULATOR LOOK LIKE A 4INCH X 8 INCH CAN,WITH A PRESSURE SWITCH OFF CENTER ON THE TOP.THE LINE GOES FROM THE COMPRESSOR TO THIS CAN,THAT IS CALLED THE SUCTION LINE (LOW PRESSURE) GOOD LUCK Im pasteing this a couple of places because its the right answer! P.S. be sure to use a guage!
