92 Cavalier AC leak

70monte on Mon August 27, 2007 5:40 PM User is offline

Year: 1992
Make: Chevrolet
Model: Cavalier
Engine Size: 2.2L
Refrigerant Type: R134a
Country of Origin: United States

My 92 Cavalier that I converted last year to R134a has developed a leak at the service port that is located in the hard line that goes from the evaporator to the accumulator. The service port was apparently used for the intial refrigerant fill. The port on the accumulator is used for the low pressure side now.

Does anyone know if the top half of this port comes out and can be replaced, or will I have to get a new hose assembly? It looks like its leaking from under the screw on cap and the port does not have a schrader type valve in it.

Does anyone have any ideas on fixing this? Thanks.

It unscrews. Put a wrench near the bottom of it and grab the top with pliers and the fitting will unscrew. Of course the system must be empty or you will lose all the refrigerant.

I replace the fitting on every car I work on because they always leak.

Thanks for the reply. Do you know if this part is available to buy or what the correct name is for it?
