R134 conversion? for the gurus to guide me!
Hi y'all. just picked up a 1990 SC 4x4 2.9 Manual. how can i tell if it has the old R-12 system? will the low pressure ports for recharging be different? i know about not mixing R-134 with R-12. if i do have the R-12 (1990) , are there any tech articles for the conversion? (orifice plate, condenser, compressor?) TIA
