66 Corvette AC STV valve leak

[Gary N.]

Recently recharged the original AC on my 66 Corvette and found that I am getting a Freon leak around the STV valve. I am guessing that I am getting a leak from the rubber diaphragm in the valve. Has anyone had this problem? Is the valve easy to rebuild? I see they offer a diaphragm rebuild kit. Anyone have any instructions for the rebuild? Any help would be greatly appreciated.
Thanks

Gary, I know some have rebuilt theirs, I sent mine to Classic Auto Air in Florida for rebuild. Good luck, Don H.

The diaphragm is simple to replace. The hard part is getting out of the car then back in. It is spring loaded. When I rebuilt mine I had in in a vice and slowly removed the screws. I cleaned it with alcohol, installed the new part and reversed the process. I used an NOS part as it comes with the metal attachment, was about $60.00

Good luck
