Chevrolet Repair: 2002 Chevy Venture, riding dirt bikes, chevy venture

Question
I have a green fluid leaking out of what I believe is an airconditioner line.  It is under the van going to the rear of the van (it has rear ac).  It is green in color.  I don't think it is anitfreeze because I use the orange colored aniti-Freeze. Would this be an ac line and would the fluid be green coming from an ac line?  It is leaking in two areas where the rubber piece ends and the hard line begins.  It is leaking even when the ac is off and the van is sitting.  What are my options of fixing this? Would the whole line have to be replaced or could the leaks be fixed with clamps at the seams or something.  I don't see any visible holes in the rubber.
Thanks for your help.

Answer
Hi Jeff, Sorry I didn't get back to you very fast, I was out riding dirt bikes for the first time this year. The green stuff is A/C dye it the oil, These lines leak because salt gets into the rubber and eats away at the lines. There is 2 ways to repair this problem, replace the lines with OEM lines or put a/c compression fittings on the lines and run rubber a/c hose. Using the rubber line is a easy way to repair the problem and should out last the OEM stuff.

Hope this helps

Have a Nice Day            Mark
