## Questions & Answers

**Q: How long should i keep the engine running for UV dye to show up? And do i have to rev it or just idle it?**
A: Since I used the fluorescent dye to detect leaks from the power-steering system I had to drive my car around for approx 15 mins to actually see where it was leaking from. At idle I couldn't see any leaks. After the drive the leak was pretty obvious and the UV light picked it up right away.

**Q: are glasses  included?**
A: Yes. They are an amber/yellow color

**Q: does it come with dye for a/c**
A: Yes it comes with a/c dye

**Q: Can the kit be used to identify transmission leaks?**
A: transmission leak should  b readily identifiable by the red tint already in   the  fluid     to  b  sure   either  water blast   or at least  hose off under hood   all  oils    and then get on fairly clean  surface to  see if   red  oil  shows  up     keep   in mind  u could have   more than one  leak   and  some  people will  put  trans fluid in power  steering  complicating  matters
