Report How many kg in AC? in Interior/Exterior/Lights/Glass/Alarms/ICE/HVAC Posted June 23, 2019 The AC circuit is too big in the Esprit. I need charge with R134A (brute force over R12) every year, +/- in May. For me, it is minus onerous recharge the system than dismount, search and repair ! So, with this method, I can survive the days of bigger temp. in Spain. Probably, the leak at my car is in the evap. but work at this around is inimaginable by me. New oil in compressor, inspect and change the O-rings accesible and enjoy 4 months, no more.
