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...

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...

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...

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.

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...

"Your Mileage Might Vary," as the expression goes, but I normally try to evacuate a system for a minimum of one hour. Special circumstances can and do present themselves, though. For example, if a vehicle with an A/C problem comes along and the owner needs it back in about two hours, that ...

I myself suggest what I know to be best practice here on an established system. None of us gets to work on a virgin system very often. Your method is analogous to the stock market, ie, past performance is not a predictor of future performance. I also use a vacuum gauge, and the ideal vacuum is 500 ...

I bought a r1234yf can tapper and the threads are 1/4" sae threads. Of course that didnt fit.......this has been so frustrating and confusing getting information. I need to buy another r1234yf can tapper now that has 1/2" acme thread. Hmmm...I wonder whether the package was mislabeled or ...

Thank you, sir. I'll investigate this further.

So what i'm gathering is that I need to flush each component ( unhook the lines and run the flush on each and then hook back up) , replace the accumulator, and start over. Right. It's a lot of work to get all the oil out and to re-fill it, but it's something you'll need to do before re-charging the...
