Review on Wisepick Injector R 134A Quick Coupler by Sean Pierre

Excellent pump. You only need to add 2 ounces of PAG oil to the system. Spend time and money buying these 3 ounces, 2 ounces of oil and 1 ounce of freon. Not enough pressure to add to the system I just filled with 36 ounces of Freon. After replacing the compressor, condenser, and battery, I skipped counting the amount of oil needed for the system after disconnecting the AC sensors. This pump saved the day.
