SOURCE: I want to add refrigerant to my 2005 Buick

It depends on the size of the cans!

The low side is the "thick" pipe that comes straight out of the inside radiator (evaporator) to the compressor, the high side is the thin pipe, running from the compressor to the outside radiator (condensor), then the liquid receiver (the part that looks like a soda can) Add a can of freon while the car is running with a/c on, check the sight glass on the liquid receiver the whole time. If there is enough freon in the system the sight glass should look almost full. If it's not enough, add another can.

SOURCE: locating the High side and Low side AC gas ports

Easy. find the compressor. The larger hose attaching to the compressor is the "suction" side. This is where you install the refrigerant.

The smaller hose, whether rubber or metal as it travels to the passenger compartment, is the high pressure side.

After installing refrigerant and as the compressor is running, the larger hose will feel cool and the pressure side will feel hot.

There are two ports, one is larger than the other and both have a threaded plastic cap on them. The smaller one is the low side where you can check your R-134 pressure.
