Re: High Pressure Side ?
Sure...Is the fan working? Good airflow through the condenser? Fan shroud in place? Air going around the condenser instead of through it? Anything externally blocking the condenser, like leaves or a plastic bag? Is the condenser internally blocked due to a faulty compressor shedding debris? Is the c...

Re: Expansion valve for 1970 Clardy under dash
Appreciate your posting the attachment. That system originally required less R-12 than I thought. Kudos to the OEM for specifying the exact weight-of-charge in 1960.

Re: Oil Analizeer
I'm not familiar with the Oil Analyzer Test Kits that you mentioned. But as for the yellowish-green fluorescent dye, only a small amount should be added to the A/C system for leak-checking purposes, typically around one to two tablespoon's worth (about 1 fluid ounce or less). What you already added ...

Re: 12a chart
Adding to the comments just above, I don't blame Canadian citizens who want to work on their own A/C systems for using alternative refrigerants, since R-134a is very expensive and nearly impossible to get in Canada unless you're somehow certified and employed in the business. That's my understanding...

Re: Continued from my previous thread: Plans for 90 civic A/C rebuild with newer gen Sanden compressor - remaining quest
Also, for reasons of understanding, if the TVX superheat was much, much higher than 8°F, how would this be felt in system performance? I'm not a MVAC engineer, but to answer your question, I believe that with a much higher TXV superheat, the evaporator will be warmer because the liquid refrigerant ...

Re: Continued from my previous thread: Plans for 90 civic A/C rebuild with newer gen Sanden compressor - remaining quest
The important point to remember about superheat is that you don't want any liquid refrigerant to enter the compressor after it exits the evaporator because any liquid will "slug" the compressor and most likely, damage or destroy it. The refrigerant will be in a superheated state from the e...

How about the original TXV...is it still serviceable? A TXV doesn't "care" whether it's R-12 or R-134a that's used.

Re: Leave well enough alone or charge AC system? Older Hondas
Place a thermometer in the center vent and keep it there so that you can monitor A/C performance as you drive. Should temperatures rise into the uncomfortable range, you'll know immediately that you have a problem, verified by the thermometer.
