Ac Problem

[racr16]

My ac needed charged... i bought the r-134 and tried to charge my ac at the firewall on the suction side... the fitting on the suction line would not allow me to connect the r-134 fitting... The fitting had female threads and a hex head 1/4 inch below the top...

I assumed that it was not converted and bought a conversion kit ... i unscrewed the fitting that was on it because none of the conversion fittings were made with male threads for the suction side... when i unthreaded the fitting it released all of the charge in the a/c because there was no shrader valve under the fitting...

my problem now lies with the male threaded stem on the suction line... it is a smaller diameter than the r134 conversion fitting... i have talked to 3 different service advisors at 3 different dealers and nobody has any idea what i am talking about...

has anyone had this problem with there SHO and how did you solve it...

99 SHO

I have yet to have troubles with my 99 SHO ac. I have always had good luck working with goodyear on all my AC issues.

From Porsches to Gen 1 and 2 SHO's.

knock on wood for me.

Good luck!

your sho has to be R134A, unless a previous owner converted it to R12????????
Are you sure your you had an R134A fitting when you tried to charge it??

You don't need any conversion kit. Sounds like you're trying to hook up to the high pressure side. Look for another valve to fill it with.

There is the other one by the overflow tank. I can't remember but when I tried to do this a couple of years ago I had the same problem. I ended up taking it somewhere to do a complete flush and refill.

figured it out... the plastic fittings on the r134 tanks won't fit... it is converted but the fitting has a hex head instead of the normal round lip to attach the compression fitting too... because of this the pastic fitting wouldn't work... i got a hose with a metal compression fitting and it works fine....
