Where do I add freon in a 2003 buick century?

This job requires special tools and training, it is VERY easy to get hurt badly. It is illegal to not recover any refrigerant in many parts of the world. I suggest that this job be performed at a qualified shop.
Refrigerant goes in the low pressure port.

Where is low side port to connect charge kit on a 1998 Buick Century Custom? Also, to be sure what type of refrigerant should be used? (R-134a) or different Thank You, Brandon

1998 Buick Century is factory-equipped with R134a refrigerent.

As for the service port, you just have to look for it. Not even the factory service manual will tell you exactly where it is located. It will be either on the accumulator itself or in the low pressure line between the accumulator and the compressor. (see diagram)

Take it to a repair shop ,so you don't do more
harm than good & you will, if you try to add refrigerant
only to have it leak out & polute the atmosphere

I want to add refrigerant to my 2005 Buick Century... 6 cylinder. How many cans; it says to charge using the low side. How do you determine the low side

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.

Where do i add freon to a 1998 buick century?

You don't...ask a local A/C shop to check your system...often $29-39 and they add/R314 and diagnose it for free.
Good Luck
