Engine Size: 4.3
Refrigerant Type: R134a
Country of Origin: United States
I have an old volvo stationwagon with a chevy 4.3 engine in it. The factory AC uses an expansion valve. However, I would like to make it an orifice tube setup to make it easier to work on. Is this possible? And if not, will the chevy AC compressor, designed for the O-tube AC system, work with the TXV system? I need some help please! Thanks!

ues the TXV and put a sensor in the evaporator to cycle the compressor so you do not get a freeze up on the evap. You will need a larger more efficient condenser. A complete flushing of the evap with the TXV removed will be needed. You will need a TXV that is designed for R134a for better results.
A TXV system generally works better than OT. American car companies introduced the CCOT design in the 1970's because it is cheaper to build.
Compressors are the same for either.
