Gents,

I've got a 1993 240 Wagon, with R134a AC system. It's been evacuated years ago but hasn't been put back to service (no ozone warnings please..already got them!! Thx)

I'd like to pull vacuum on the system to check for leaks before conducting any required repairs. I can find the low side port, just next to the drier but for the life cannot locate the high side port. The compressor is Seiko SS-121DS, so the are no ports on the hoses in/out. I've traced the hoses from the compressor to the condenser to the evaporator but can't seem to find the high side port. Should be a wide quick snap fitting that I am expecting...

Any help would be appreciated.
Thanks in advance!
Alex...

 

Typical location is 30b in the pic...

 

Thanks much. That's also where I thought it was from the same diagram I found on the web (except the descriptions). But, nothing in that locale on mine. Just a straight hose from the compressor into a pipe leading to the condenser. I read elsewhere in several places also where folks were saying that year volvos did not have a high side port. All servicing from the low side only.
I succesfully pull the vacuum and recharged the entire system with low side only port. So far, all components working as expected.
Thank you for the assistance!!!
