R12 TXV is usually opening around 36F although i measured a few at 31F (?)
I have not measured a TXV set for 134a as they where all new in the box...all TXV's are now set for 134a.
They are really to stop the evap' core from freezing and from freezing the heater core too. I had a vehicle that actually busted two heater cores in a few months. Turns out the TXV was never turning off the CC and it froze the condensate and then the coolant in the heater core....because the owner...who will remain nameless...said he had antifreeze free at work and would add it later....but never did.
I never let a vehicle leave now without antifreeze in the coolant at at least 50% mix. Ho hum...ain't life grand?
BTW...they seem to all close again at 42F.
