Hi all,
I was doing some engine mods on a truck the other day & a sparkie (site A/C man) came up to regas the A/C (CCTX) (134a) system & I asked him what pressure he was going to gas the system to for the ambient temperature & his reply was, I don't worry about that I just add gas till I see the gauges kick, can any one explain this phenomina?
Thanks - Leigh
