Let me adjust that question :}
Does the AC system on this car have a "high pressure relief valve" ?
If i wanted to install a "high pressure cutout switch"... which one and
where should i buy such a creature ?
Thanks for the help Tegger,
AC does not work (well has not worked since last year). It was completely
void of refrigerant as there was No pressure on the lines according to the
I figured now would be a good time to convert to another refrigerant like
After doing some research about converting to 134a there was mention of 134a
operating at higher pressures and the need for installing "high pressure
cutout" (if high pressure relief valve existed) to comply with EPA SNAP
Plus installing 134a service port fitings and a new 134a label etc...
As for the problem ....
I figure there must be a leak so i pulled a vaccum on the system to confirm
and it held 27" for at least 45 min until i disconnected everything so i
wonder why/where the refrigerant went ? maybe bad schrader valve or a high
pressure leak . So i plan to search for leak after i make all the other
Thanks again for the help.
