    uv leak dye

    hey guys, just read a alod thread were alot of people are bashing the use of dye. Dye has worked great for me several times, very easy to visually check system and find leaks most of the time. Chevy puts in every car they make since 2001. i have never seen it hurt a system.

    Can anyone really honestly say they dyed a system, and shortly after it hurt it? curious . maybe i should stop using it? it does work really good to find leaks.

    It also voids the warranty on equipment if it is used. It displaces what the filter drier catches and blows it out the back of the drier. Plus it makes a mess of your gauges.

    messy and un-necessary. If you cant find a leak without it, u r in the wrong trade.

    It is a great tool to have available for situational use, but I wouldn't use it in every system.

    Maybe your experience is with crappy products, Spectroline Ar-Glo doesn't do either of those things.

    Only if the system has been over treated.

    How would you propose to exactly pinpoint every leak in a system that is in an environment where you are not allowed to use an electronic leak detector, like a walk in for volatile HAZMAT storage?
    If more government is the answer, then it's a really stupid question.

    I used to use it. Works great. Never had a problem with it.

    Haven't had the need to use it lately.

    Never have iether. like i say GM it uses it in every vehicle made since 2001 from the factory.( was a GM factory tech for 8 years) all with 134a. It is easier by far to find leaks than electronic IMO. yes-do it right, and don't over dye. it only takes an ounce or two usually.

    Anyhow noone ever answered that they have actually seen it cause damage to an otherwise good system? so, has anyone?

    Also then, what are your favorite detectors/brands/methods for leak checking. If someone has proof i would like to stop using it, but it does work great for finding leaks.

    Used it once when I was a baby tech. NEVER agin. 23 years later still haven't had a leak I couldn't find with out it. Don't care if its good, bad, or indifferent to operation. May help you on the first leak but then its everywhere. Here a leak there a leak everywhere a leak leak?

    Preferences:

    Electronic: H-10. Have a H-10 PM and a H-10 G. Very satisified with the PM, only used the G a handfull of times.

    Soap Bubbles: Current favorite is a homade mix of awsome cleaner/degreaser and water. Also have super blue and some thick yellow stuff (not sure of brand). Nu calgon brand works good too.

    Also have a length of 3/8 od hose, stick one end in my ear, run the other end around the evap elbows or whatever I'm checking.

    I think the last time I used dye, it was the spectronics brand.
