Evaporator ??

[winfred]

when changing a major component i strongly recomend a new drier, but not when the system is only open a few minutes to change a o-ring

Thanks Winfred.


Follow-up question:
Is it really necesary to replace the drier after I change the evaporator and expansion valve? While searching, I've seen some say that you have to replace it every time you open up the system. Any thoughts?
