Stop Leak for R1234yf Systems, R-1234yf Stop Leak

Follow the instructions in the description, work super fast and make the a/c better than before, you have to have more gas r1234yf because you have to refill to the point 35-40 psi no more in the lower pressure port, I used on my suv since 2 months and no issues

This product is good. I used it on my Chevy Equinox 2018 when suddenly the air conditioned was completely hot. Used a can and it started cooling inmediately. Three years later still perfect.

The Stop Leak R1234yf system comes with a can of Stop Leak and a hose for connecting the can to the low-pressure side of R1234yf systems. If you are familiar with recharging AC systems, you'll find this system reasonably priced and relatively easy to use. I decided to give it a try and, after separately adding R1234yf my system, my AC system has been working and blowing cold for a month. Three things to keep in mind are: 1. This is Stop Leak and not R1234yf fluid for recharging your system. 2. Although the hose has a valve, the valve pierces the can, so you have to plan on using the can up, or throwing-away what doesn't get used. The hose is specific to cans of Stop Leak and will not work on cans of R1234yf fluid. 3. Plan to still have to add R1234yf fluid to charge your system. Get a system with multiple cans of R1234yf fluid and a hose with a gauge so you can see how much pressure is in the system. My story: The R1234yf AC system on my 2016 Honda Civic suffered from a slow leak that got resolved through periodic recharging. (The charge tends to last the whole season, maybe two.) My Honda dealer said they replaced most of the system (except two hoses) and, although there are documented factory issues, are no longer warrantying repairs. They want over $1500 to replace the two hoses and charge the system. R1234yf is expensive but I figured for less than a couple hundred dollars a charge can at least buy myself a few years by recharging the system myself. Hoping that where I have such a slow leak, this will be a permanent fix...so far, so good. Note: The Honda AC System has sensors to prevent compressor operation if pressure is too low, OR if pressure is too high. If it is too low you will need to put a jumper on the respective contacts in the fuse block to operate the pump. If pressure is too high, you will need to bleed some gas to allow the fluid in the can to pass into the system.

My Honda clarity has AC issues every other summer. The dealership dragged it until the warranty expired. This summer the system was not putting cold air. Wanted to try this 2-in-1 sealer and refrigerant. Was very easy to refil, all instructions very clear. Now I can enjoy cold air . So far so good.

No cumplió con lo prometido

Was a bit skeptical about this product before buying. Installed it added freon and pleased how it worked. Time will tell but the ac on my 2017 Silverado is blowing 40 degrees.

I placed the can in warm water for15 minutes as I do with all refrigerants to get a flow. I used a can of this company's freon (4oz) after vacuuming the system then I use the Stop Leak of the same company and my low-pressure gauge froze on 10 psi and never able to put another can. I used 3 cans of their 1234yf refrigerant on another unit the same day and the gauges worked fine.
