I put the r152a in my system last year after ditching the r134. It's starting to warm up here in the Socal desert so I thought I'd just update that the r152 is still going strong. Pulling low 50's temp at vent idling ambient outside temp was ~100 (the outside temp reading is higher on the display because the car has been idling for a while in the same spot). When I take it out for some driving I'll get the temps again while rpms are up. I'm guessing I should still be pulling vent temps in the 30's....maybe even lower since its not 110*+ outside.


*UPDATED* Took car out on the Hwy today, 95* ambient temp and was pulling 30*F at the vent. It's been about a year now and considering we extreme heat as high as 120*, I'm calling this a permanent solution.
