The low pressure port is the same place that you add Freon to your air conditioning system. The low pressure port will have a blue top.
2 pounds of r134a. Not r12.
Connect a freon gauge and tank to the low side ac port of the 97 DeVille. With the engine running and the ac on high, open the freon valve. Shut the valve when the ac gauge reads full.
Using a set of gauges you will put the blue hose on the low side which is the suction side and the red hose on the high side which is the discharge side and using the remaining yellow hose you will attach the can of freon and add the correct amount plus add oil as well....
