are new AC parts made to be r134a compatable

DadTruck on Tue July 19, 2011 3:03 PM User is offline

Year: 1983
Make: Dodge
Model: D-150
Engine Size: 225
Refrigerant Type: r134a ?
Country of Origin: United States

I am in the process pulling the parts together to add AC to my 1983 D-150,

I have a under dash unit with evaporator, dash controls, dash vents, plastic pipes that move the air to the vents ,,,from a 86 D-150 that will fit nicely

I plan to purchase new compressor, clutch, condenser, lines, dryers, expansion vales and other misc parts...

My questions are:
1) since the 86 and 83 ac parts when new were r12 units,, will I need to convert anything on these "new" components if I plan to run r134a. like o rings, orifice sizes,,, or are new parts made today, made for r134a? Since I am buying a new condenser,, I'll get a parallel flow unit.

2) The evaporator from the 86 unit did not have the lines plugged when it was removed,, may have even sat outside for some time,, I can see lots of debris in the hose connection ends.,, will a flush work on that? or is it best to just buy new condensor also?

thanks

Take the txv off and flush the evap.

All the other components will be R134a depending on who you purchase from.
