R12 vs. R134a Pressures

hjc149 on Fri August 31, 2007 12:19 PM User is offlineView users profile

All things considered equal, what would be the difference in pressure readings for both lo and hi sides with a vehicle using R12 and then converting to R134a. For example, if the low side with R12 would be 30, what should it be after switching to R134a, again all things considered equal or in other words, both systems working properly.

Apples and oranges!

No way to compare them evenly without component changes. If a true PF condenser of the same size is used to replace the OEM condenser. Charge levels and pressures are very similar across the board.

Do you know what size the thread is on the shaft of a 95 deville compressor DA6 I believe?
Thanks
