A/C Change over
Here is a picture of my A/C with R-134A freon in it. I went to the junk yard and bought it out of a late model 80's truck. Then went to parts house and bought the new accumilator, inline expainsion valve for R134-A and installed. You have to block off part of the outside box around the new avaperator to force the air through the fins, and not around them. It's a little smaller than the old one. I then ordered the new compressor for R-134A. I took the dryer out of the system and used my old condensor, and it runs at 35 degree's all day long. It takes it a little bit longer to cool off, but once it does it's there. I have had this system in the truck now for 5years are so and haven't added no freon at all.
Best part is it didn't cost me but about $250.00 total for everything, but a buddy did the charge and vacuum for free, all I payed was for freon. I installed everything in my drive way then took it to his shop.
