Ac conversion
I have a 1973 duster with factory ac and want to convert to r34. What thing do I have to do. Like what parts do I have to replace ect.
Take the compressor off and dump the mineral oil out of it, not compatible with 134 freon. Dump a couple oz. of the new PAG oil in, work it around and dump that out too. Ready to reinstall the compressor, but first clean out the rest of the system and install a new Reciever Dryer. Couple of ounces of Pag oil in the empty compressor too, check how much pag oil to use.
Front condenser can be rinsed out with a fast dry brake parts cleaner and blow it out, then reinstall with new O-rings.
Buy 134 conversion fittings online or at local parts store.
If your compressor is questionable, now is a good time to put on a new mopar reman compressor so the system will work well. Check the magnetic clutch to see that it is functuoning too.
Reassemble, and pull down a full vacuum on the system and close it off for a half hour to make sure it does not leak down. Then recharge with the recommened ounces of 134 freon for your system, same as what it took for the r12.
