  1. Can red angel be added after sysrem is full in which leak was found with dye? Does it matter how much is in system when not using gauges? R Z

    1. Robert-

      You definitely do not want to overcharge the system. The can of Red Angel A/C Stop Leak contains 2.5 ounces of R-134a.

      Red Angel will not harm or damage any shop equipment; we guarantee this. The product is reclaimed with the oil.

      Thank you!


  2. Can I use r134 that has top leak in it as well such as ac pro? Will it interfere with red angel working effectively?

    1. Jeremy-

      We do not recommend mixing 2 stop leaks together within your A/C system. You should use regular R-134a (without stop leak) if you are adding Red Angel A/C Stop Leak to your A/C system.

      Thank you!


  3. Can Red Angel be used in a hydrocarbon-filled system? I replaced the R-12 in my vehicle with Duracool 12a Hydrocarbon. I have a leak which I am unable to locate using a sniffer or dyes. Will Red Angel properly mix with Duracool?
