PRODUCT OF THE MONTH—2724—R-1234yf Hand turn Oil and Dye Injector

  • Most cars will not engage the A/C compressor when there is an inadequate supply of oil in the system.
  • You may prefer to have UV dye in your system before there is a leak so if your system fails to adequately cool, you can readily spot the leak.
