Air Conditioning Leak
If your Air Conditioning System seems to loose its cool, no pun intended, it is most likely do to a lose of freon. Freon itself is colorless and can be difficult to locate. Most shop mechanics will add approved fluorescent dye to the Air Conditioning system in order to help locate the leak. Once the dye has been added to the AC system and freon level topped off. Run the engine for 10 - 15 minutes with the AC on Max. Look for signs of the dye around all AC system components. Once you see where the dye has leaked out it is just a matter of swapping out a bad o-ring or replacing the compressor (shown above). The Dye can be easier to see under UV light but is not necessary in all cases.
