Foxbody (A-C) R134a Conversion

[onjacks]

Everything under the hood is new.

New accumulator, SN95 condensor, custom lines, Reman (fox) compressor &
variable orfice valve.

should i still flush it. all my parts are new, but they have been hanging in the garage for about a year.

any ac pros on the board?

Ive got alot of money wrapped up in this and just want to make sure its all right.

How long has the accumulator been open? What about the rest of the system? I had two threads and Deville had one or two with tons of great tips.

In the end, I built my own system from varius vehicles, all new and kept sealed until time to charge. Put it on a vacuum for an hour plus, then charged it up.

The system is all new & never used. Its just been lying around the garage while I've been finishing up my coupe. I Just had my lines built today. Main concern is having dust/trash from them sitting. Should I just blow the system out with air minus compressor?

Is flushing an AC something you can do at home? I've been wondering if I should get my AC flushed as well. I've been using it just to get air because I never refilled it after the rebuild. Perhaps I've already contaminated it?

It wouldn't hurt to flush the condenser and evaporator out and your lines don't flush the accumulator/dryer. Go down to the parts store and pick some AC flush up and pour a little on followed by a lot of compressed air.

If the system was never opened and left for a long period there is no need to flush.

just pull avac on the system and then add the refrigerant

It wouldn't hurt to run ac flush through the lines, dont flush drier or compressor they both should have been sealed until you are ready to connect the final lines to them and pull vacuume to test the system for leaks for 30-60+ min before charging the system.

Be sure you install a low pressure cut off switch that is set for R 134. There IS a difference.

i was reading somewhere that you can turn it counter clockwise abot 1/4 turn to work with the r134a??

[onjacks]

Also, the reman ac compressor, I believe, came with oil in it.

Not sure how much was put in, or what type.

Should I just pour it out and start over?

Sorry for all the questions, but I've got alot of money going into this to do it wrong.

Don't mean to hijack but I just came from autozone and they have some BS flush in a can.I guess you hook it up and flush. Is this crap like everyother DIY home a/c kit

Important to have the correct type of oil in the compressor (and the correct amount). If unsure about the type of oil in there I suggest you replace the oil.

If your condenser is an R12 type it will help to get more air over it by adding an electric fan or a higher capacity if already electric. 134a needs more condenser or more air over the condenser than R12. My Fox had an electric fan and upgrading the fan made a huge difference.
