Lichamp Automotive AC R134A R1234YF Valve Core Remover and Installer Tool Set, for Standard and JRA Valve Core Couplers

Worked as advertised. I own an Infiniti G35 Coupe. I was done with the whole process in 20 minutes working slowly and carefully. Watch a you tube video carefully to understand the process. . Pieces of advice. #1 Check the tool to make sure that you are using the correct size. There are two sizes. They are interchangeable between the high pressure (red) and low pressure (blue). #2 Hand/finger tight is good enough. do not crank down hard. Slow and careful is better. I noted that this is a high return item. Suspect that once the job is done, they are returned as you only need to do this once every 100,000 miles.

Worked perfect to change low pressure Schrader on a 2012 Ram 2500

One of the best tools I had ever seen.Ease of use is also another point. Just the valve side feels a bit loose, but doesnt mean the seal is not working.Very functional. The design is convinient as well.

Fixed our F53 engine AC. Wasn’t blowing cool at idle. Turns out the low pressure valve was leaking. R134a was low. Evidenced when I tried to charge it. Bought this little valve replacement tool on Amazon for $29. Replaced Schaefer valve now no leaks. Charged up. Works great. Watch a video. People complain the tongs don't grip the valve for extraction. It's not supposed to. Pressure pushes the valve out after you unscrew it. Unscrew at least 6 turns. Be careful. Be accurate. Works exactly as it should.

With the cost of everything going up and up these days, I've returned to doing all the minor repair work on our family's vehicles. My wife's Explorer AC system has a small leak in the high pressure JRA valve. The procedure for the use of this extractor is pretty straight forward. I attached it to the service port, pushed the rod down and turned it a bit until I felt it seat fully on the core, then I attempted to screw the core out. There was a lot of resistance, but eventually the rod began to turn. I would point out that I did not employ the use of pliers of any kind to turn the rod. I only used my hands. I kept turning the rod of the extractor and when it felt free, I slowly pulled the rod up, engaged the the shutoff valve, and then unscrewed the rod assembly from the housing of the extractor tool. When I looked at the end of the rod, not only was the core not there, but the end of the rod designed to fit over the core was missing. When the rod had finally begun to turn earlier it wasn't because the core had come loose, but rather the tip of the rod had broken free. In the first picture you can see the end of the rod that is now stuck on the pin of the JRA valve. In the second picture you can see both rods that came with this extractor. You'll notice you can see that the larger one I was using on the JRA valve has threads at the end because the tip screws on. In addition, my efforts to remove the tip from the valve core eventually caused the brass knob at the other end of the rod (which is connect only by the pressure of a tight fit between the knob and the rod) to pop off. There are many reviews on this product from those who were able to use this tool successfully, but in looking at other tools like this I've noticed many of them have a rod that does not have a threaded and screwed on tool tip. I'll be returning this. I can only hope I can manage to remove the tip that is still stuck on my valve core pin without destroying the valve core and/or discharging all the refrigerant into the atmosphere, and I'll be purchasing another extractor that is more solid and up to the task without falling apart.

After over a month trying to figure out where the ac was leaking on my 97 Saturn SW2, I finally noticed a slight release of pressure when I removed the cap on my low pressure valve. Never had a leaky valve before, but then I'm not a professional mechanic. Ordered this kit, and when it came in, I used one of the included valves and replaced the leaky one in 3 minutes without loss of coolant. It's a brilliant, simple idea that just worked. I appreciated them including a small assortment of valves, that was very convenient. Been a few days and no sign of any leaks.

Worked great on the low pressure side in a r1234yf system. Tool locked on and easily extracted the valve stem and installation was just as easy. The high pressure tool though would not lock onto the service fitting, and the locking balls kept falling out. I ended up grinding down the threaded end on the valve for the service adapter to make it lock onto the high pressure port. I bought a second tool and it had the exact same issue. Overall, this is a good tool, but modifications needed to be made. Have not tried on r134a system as both my vehicles have the r1234yf.

Let me start with saying that only use OEM valves, it is just a waste of time otherwise.As many of you I was able to remove the low pressure valve in no time, however, the high pressure valve was a challenge. After many failed attempts I decided to use the low pressure plunger in combination with high pressure body on the high side. And it worked! It took less than a minute for the entire process. I am going to get OEM valves because included ones are not good, in my opinion.
