Adaptable Ac system as a whole to a Honda accord 1990?

I gave up on my AC system and dismantled everything. I put some dye when I refilled and I could see dye around the Tvx valve. But since the high pressure line was cool, the condenser might have been clogged too . So I took everything off. I checked the compressor and it was all dirty ( power steerin...

Re: 1990 honda retrofitted to R134 , holding pressure, holding vacuum , not cooling

Thanks for the info. I took it from an old evaporator. I had no idea whether it work or not. So I was testing it to learn how it really works. I put the bulb in Water with ice and it didn't close, but I put it in the freezer and it did...I tighten the allen nut a bit and it close a bit when I put th...

Re: 1990 honda retrofitted to R134 , holding pressure, holding vacuum , not cooling

Updates:

I have an expansion valve at home, I have been playing with. I noticed there is an allen nut taht you can turn and close/open the flow. Is there any specification to set it right for R134a? Like number of turns from a tightening position?

Cheers

Huh? The pdf does not describe that. I am referring to the right angle Tvx. It says remove the Tvx.

Re: Testing TXV's

Question: Must the test be with compressed aire only? Or it must have the same output with any source of air? Let say : With a small pump, or even bow it with the mouth?

Re: 1990 honda retrofitted to R134 , holding pressure, holding vacuum , not cooling

Are you really seeing liquid in the sight glass, or just clear gas? You should see it fill up and clear with bubbles and liquid when you start and stop the compressor. Do you know of any history of a stop-leak compound being used in this system, or having a blown compressor and replacing it without...

Re: Condenser lines

Forums work better if people don't start new threads about the same problem they're having. Bump up your original thread with any new findings. I am sorry about this. I cut this discussion and pasted in the other question I asked which refers to the same car. Please delete this post. I tried to do ...

Re: 1990 honda retrofitted to R134 , holding pressure, holding vacuum , not cooling

The line getting into the condenser is hot (not warm but hot). The same line leaving the condenser is somehow cool.. Not cool but definitely colder than ambient. Is this the way it supposed to be?

Re: Condenser lines

Depends on the vehicle- all GM trucks (front only systems) have their expansion device (OT) in condenser outlet- so yes, condenser line to evaporator will be cool---Most cars have their expansion devices at entrance to evaporator, so no, it should be warm---A condenser restriction can act as an exp...
