Hyundai Galloper po, the re-badged Pajero boxtype. i remember my technician told me before na tinanggal nya daw yung solenoid valve, so kahit naka-off yung rear A/C, nag-cicirculate parin ang lamig on both front & rear coils.

another technician told me na dapat daw front and rear expansion valves are the same para pantay ang lamig, how true is this?
