OMT R-1234yf 4-Port AC Manifold Gauge Kit Review (Honda Clarity AC Recharge)

I'm doing a quick recharge of R-1234yf on my 2018 Honda Clarity, using the affordable but well build OMT R-1234yf 4-Way Manifold Gauge Kit that I bought from Amazon: amzn.to/46EmI6u and R1234yf refrigerant: amzn.to/46Hd4Ab My car started to blow warm air a couple weeks ago. No vacuum pump was used today, I just checked the pressure and it was low on refrigerant so I added about 7oz. For a complete AC refrigerant service including vacuuming the system, see my other video here: • Ford Mustang R134a AC ...

Thanks for the videos!! I watched the mustany video, but my real issue is that I have a 2018 honda clarity like yourself and have my a/c getting off an off... I'm ordered this OMT kit and some R1234yf... I'm also hoping I can just top it off like you did. Did you have any more issues with your Clarity's A/C? IF so did you just add more? or purge? or bring it to Honda, I understand they have a TSB extended warranty on A/C compressors. I would love to have instructions like the mustang video/HArbor Frieght system.... Any other thoughts if I want to purge? Where did you find the pressure to Temp/humidity values for the Clarity? THANKS!!!

I did only top off instead of purge the first time I did it half a year ago. It blowed warm air again after about 4 month. I think my AC condenser had leaks, maybe covered under Honda warranty. I plan to bring the car to dealer for warranty check on condenser. Before that I may just do a full purge and recharge with two full cans. The value was from some forum from someone posting the Honda Clarity mechanics manual

Are you sure the curved side of the hose connects to the gauge? The ad for the product shows a photo of the gauge and hoses connected different than what you say.

It really doesn't matter which end you use, depending on the application; on some vehicles or AC units, it may be easier to use a curved end for connecting to the unit. The most important factor is ensuring the connector doesn't twist itself loose during the test.

Hello, thanks for the video, very informative. I had a leak in my 2017 Sierra’s condenser like most gmc/chevy trucks do. I pulled consistent vacuum for 50 minutes. I let it sit for one hour with no changes. I add one 8 oz can of freon. It took a while 15+ minutes. I had it on a scale and watched the frozen condensation disappear. I turned off the valve at the can and added second can. The second can never got cold and did not decrease in weight. I tried a third can with the same results as the second can. Did I accidentally add air to the system changing cans? I’m puzzled. Do I have other problems? Compressor turned on and stayed on the entire time. No change in temperature on the thermostat I had mounted in the center vent even after the first can was completely empty. Minor condensation dripping from the evaporator coils. WTF did I do wrong? I used the same OMT manifold with an OMT Vacuum Pump, 4.5 cfm.

Sounds like other issue maybe present in the system, need to diagnose the system use pressure readings from the gauge: rechargeac.com/how-to/ac-system-pressure-chart/
