SY66 Automotive Air Conditioning R134A and R1234YF Valve Core Remover and Installer Tool Set

P. J. Corselli: Great tool. Almost fun to use and way easier than blowing the entire charge, vacuuming and recharging.
Did not come with 134-A cores which would have been nice.

S. Duran: There are lots of reviews saying the tool doesnt hold onto the schrader valve and you need to smush the end of the fork closer together to make it work. That may be the case with certain applications but here is what I had to do for my Honda Element and this will presumably be the case for most Hondas. The blue outer piece will be for the low side, the red outer piece will be for the high side. The red one was real tight and difficult to get on and off but that may have been because my line was damaged or dirty. The blue inner piece (the part with the fork to grab the schrader valve) needs to be used on both sides. They are interchangeable. Remove and replace the low side with the blue tool as it comes. Then take the inner part out of the blue one and put it into the red one. You will then be able to remove and replace the high side valve. Inside of the forked end is a oring. That oring grabs the barb on the top of the schrader valve. It works perfect for both sides. Low side takes the bigger schrader valve and the high side takes the smaller size. 5 minute job and it fixed the slow leaks.

dd5009: I bought to change out leaking valves on a 2004 ram 3500.. low side is a small valve and high side is a larger valve .. to big for low side--to small for high.. waste of money !
