When charging the air cond which me and my cousin have done a few times.

Car is a R12 car but can easily be converted to R134 (prepared from factory) we
can only find a scrader valve on the suction side - thus we cannot connect manometers
to pressure side. There is somthing looking like an outlet for another schrader valve,
but this is plugged or a dummy without threads - suppose 1993 sevilles and eldos
are the same - can anyone explain

The high side port should be in one of the 2 lines running across the engine bay near the firewall. You must have the only factory prepared 93 in the world but go ahead and put the 134a in it. You and your cousin have done it lots of times.

Prepared for might be wrong but its delivered with R12 but should be easily converted to R134,
but I don't know how this differs from eg 1991-1992 - we have used R12 so far.

But there seems still not to be any schrader valve at the pressure side - what we thougt was is a dummy
or plugged.

Thanks - yeah it looks like this so we thougt it was a dummy - so why are the valves different for suction and
pressure side - have used R12 all the time on the car
