A/C Change over

[Andy4639]

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.

Looks like a nice installation. I am glad that R-134 is working for you over time, as we are looking at converting my son's Burb to R-134 and are concerned that it lasts.

Make sure you vacuum it out really good, and change the oil out in the system. If you do this it will all hook right up with the only hose to buy is the one where you take the old dryer out of the system.I used the old 71 evaperator instead of buying a new one. It works, but it may work even better with a new one for R134-A system. I didn't see an need for it though since mine was fine.
I think it cleans the fender area up also.
