: : I am in Australia and chickened out on bringing a unit from the U.S. and finding it didn't quite fit, or something.
: : So, I had the original compressor, Bosch (made in Japan!), reconditioned in Melbourne.
: : I would have liked the newer technology Japanese one too - allegedly more efficient.

: Have any of you completed the 134a conversion on your E-23 compressor change out? What else was changed? Is it the same as on a US auto? How about cooling during a hot day after the change over? Did you change fans on the radiator? I am interested. Let me know.
My mechanic tells me not to change over as he says that R12 is still a better choice for hot weather (though I must confess that summer in lNortheastern Pennsylvania (USA) is considerably less intense than Down Under. He (my mechanic) has also mentioned that the price of R134a is escallating due to people using it as an aresol propellant (supply and demand). Hope this helps.
