To answer your question directly you can by a kit from any auto parts store. I bought mine from Advanced Auto for $20 which had the dye, stop leak, and a UV pen. The dye in with 134 shows yellow under the light. Having said that you can look at the fittings, switch, valves and see if there is any oily residue first wipe it all clean with a rag and see if anymore shows up. The major leak that I found was at the trinary switch which I replaced. I also had to tighten the Schader valves. That was about 5 years ago and it is still cooling well.
