Coolant leak

[shane_3800]

Um, yes there is. All A/C systems contain small amounts of oil that travel through the system with the gas. The oil will lubricate seals etc. (similar idea to the drops of oil you put in air tools before use).
Ever heard someone recommended to use your a/c at least once every 6months? This circulates that oil.

Yea a very small amount does circulate but whenver I pull systems apart you don't get any leaking out. The dye however leaks out everywhere.

Ours had dye in it.
