AC low & high side on an 88 924S
I have done a bit of research on bringing my AC system back to life, but which port is the high side and the low side on a 1988 924S? One valve is located down by the compressor, the other next to the firewall. Porsche moved these ports around depending upon early or late 944.
My second question is regarding flushing the system. Do I need to flush each individual component of the AC system before I install the new compressor? Can I simply hook up the flush and shop air to the compressor hoses and flush the entire system?
