Review on 🔧 Orion Motor Tech R1234yf AC Gauges and Vacuum Pump Kit with Leak Detector, 5FT Hoses, R1234yf Quick Couplers, 4 cfm Vacuum Pump, and Manifold Gauge Set, 1/3 HP Vacuum Pump R1234yf Gauge Set by Stephen Good

I replaced the AC compressor at a dealer and exactly a year later my AC started blowing hot air. Since my car was being repaired under an extended warranty, I decided to save some money and diagnose my car myself. I bought this, paint and coolant R-1234yf. Using this tool, I was able to determine that there was no leak, allowing me to charge the A/C in my car myself. Do it yourself!
