Re: LO Side 0 PSI/ Vacuum, HI Side 100 psi
The first set of pressures with the engine at idle and the compressor running suggests a very low refrigerant charge, although to get meaningful pressure readings, the engine should be at about 1,800 RPM, A/C and blower on maximum, doors and windows open, and a known, full refrigerant charge in the ...

Re: Freon scam site
Nah...30 pounds of "make in USA" refrigerant, an oven mitt, and a shower cap, all for less than $50.00

Re: First AC Job
That sounds great. Did you have an opportunity to measure the center-vent temps, and at what ambient temperature?
Sounds like you're pretty close on the oil amount, if a little over. Better that than too little, I think.

Re: My R4 compressor never cycles, either
Curiously, an acquaintance owned a 1993 Suburban that had an adjustable clutch cycling switch.

Re: First AC Job
A belated Welcome to the Forum. Mrs. JohnHere and I took some R&R at a cabin in the mountains of North Carolina, so I've been off the Forum for a while. Reading your first post, it seemed to me that the system just lost all its refrigerant due to the condenser leak. Thus, the PCM wasn't receivin...

Re: Yellow charge hose questions
Thats gonna be tough when i need to evacuate the system to fix the leaky component..honda uses dye to find leaks and they are fixing ac issues left and right with the current model civics/accords/crvs Not sure I understand. Using a good quality sniffer while the system still contains refrigerant wi...

Re: My R4 compressor never cycles, either
Can anyone here explain to me how you adjust the low pressure cycling switch that’s accumulator mounted? I have a 94 Suburban k2500. This is the first time I’ve heard of adjusting the switch. I'm not familiar with your particular cycling switch. But IIRC, some of them have an adjustment screw betwe...

Re: 1987 Buick Grand National R12 charge
I tried to upload pics of my gauges, thermometers etc but the forum won’t let me load them. The files are all too large. As an aside, my camera usually saves photos anywhere from 2MB to 4MB, but the maximum photo size on this Forum is 256K. The best way I've found to have the system accept photos i...

Re: Evacuation Procedure
The only way I can think of to test a vacuum pump is to attach a Manifold Gauge Set directly to the pump, run it, and see what it pulls. If you're close to sea level, a good pump should pull down to about 29.94 Inches of Mercury. At higher elevations, the vacuum reading will be correspondingly less.

Re: Yellow charge hose questions
Question: I bought r1234yf PAG dye but my car 2019 CRV says it uses POE oil. Is it a problem to put PAG dye in this ac system? This is new and uncharted territory, so I'll say up-front that I'm not 100-percent sure. What I've heard is that MACS discourages the use of dye in R-1234yf systems regardl...
