Review on 🔧 Enhanced MASTERCOOL R-12/R-134a Valve Core Repair Kit for Optimal Performance by Erik Wesley

Great product, good range of different Schrader valves (yes there are different valve sizes) and a great removal/replacement tool. Couldn't find anyone in town (Baltimore) with the right tools or Schraders to change the low/high valves on my 2002 Jeep Liberty 3.7L V-6. BOTH leaked in both smell and dye tests. I was almost ready to take the jeep to the dealership until I found this kit. It was a bit pricey and I didn't want to move (even after first buying two other cheaper tools that didn't work!) It arrived today and now both my low and high service ports have new valves. (The low port is actually an Eaton SSV High Flow Core -M8, while the high port uses a standard Schrader valve core.) Get it! Both sizes were included in this kit. Anyway, good kit, good tooling, good cover for all the valves, and I finally got to the bottom of this mystery! You can't go wrong Liberty owners.
