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

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.

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.

For the price they are ok the build quality is a little loose you will loose a little gas thru the stem as the tolerances are a little loose. Threads feel very fragile.

I was skeptical at first, but I'm glad I bought it. The high and low side have two different sized rods for twisting the valve out. I made sure which one I needed and broke the one loose first. Had the new part to make sure. Worked great, I thought I was going to have to really tighten the parts together, just snugged them together. I also made sure of the clearance of the AC valve through the tool because I saw some reviews saying there was an issue, but I had no problems. This one also comes with a small assortment of valves. They are similar, but different, so look closely at them if you decide to use them. I would recommend. I also like to have tools with dedicated boxes.

I was hoping for a low cost and easy to use, solid, AC valve core changing tool set. It only meets the low cost part.When I opened the box I could see why there were so many complaints about the valve cores not coming out with the tool. The valve end of the tool did not fit the valves well at all, very loose. Still, I hoped that following the 'vacuum grease' directions would make it work. I had to try 5 times, but eventually I got my JRA valve out of my low side line and installed a new one. So, while not great, it did the job and I decided to keep the tool,... until I noticed that two of the bearings from the coupler had fallen out. This will render the tool useless as it will not hold evenly on the AC fitting.I have a Master Cool tool for the small Schrader style valves and it has a tip which snaps on the valve stem holding it securely. The tip is a separate piece attached to the shaft which allows it to wiggle a little to reach the valve.I guess I'll have to save up for that JRA kit instead.

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.

the high side and low side tools are the same sizes won't work on some systems that use the bigger style valves. And defiantly will not work with the GM style valves that need a socket.

I only needed to replace the low side valve, and the tool worked perfectly for that. The tools seem well made. I did first lubricate the shaft with PAG oil. PLEASE NOTE, before you use, check the tool and tighten down the knurled nut behind the ball valve. Mine was loose out of the box.
