<P>So I checked the high pressure side and it is at around 225PSI. Low is still 30PSI. The temp here is about 96 Degrees outside. Temp at the AC outlet above the driver is 80 Degrees. Definetly a problem! As I said, yesterday it would not accept more than a few ounces of R-134. Should I try to add again? Or does the system definetly need to be evacuated.</P>
<P>Thanks, Randy</P>

<DIV></DIV>>Thanks, I will try to get the high side fitting
<DIV></DIV>>tomorrow and check it. One thing though, and I'm
<DIV></DIV>>certainly no expert so correct me if I'm wrong: If the
<DIV></DIV>>pressure was too high (overcharged) wouldn't the
<DIV></DIV>>compressor not engauge at all? Right now it is
<DIV></DIV>>engauged constantly?

<DIV></DIV>>No, the Vanagon (or most R-12 vehicles) didn't come
<DIV></DIV>>with a high pressure safety valve, they became
<DIV></DIV>>necessary with the use of R-134a which operates at
<DIV></DIV>>much higher pressures. The compressor cut-off relay is
<DIV></DIV>>controlled by the radiator temp sensor which shuts off
<DIV></DIV>>the A/C if the coolant temperature exceeds 210F. There
<DIV></DIV>>is some type of mechanical relief valve on the
<DIV></DIV>>compressor itself.
