Excursion coolant leak-in the rear :)

Right by the front mount for the leaf spring on the passenger side. It seems these are the lines for the AC, but why does coolant run back here? Can anyone ID these lines for me?

Just an update-it is my high pressure A/C freon line, rear half. About $280.00!

Could the green be a dye from the freon? When I replaced my A/C System, I put a dye that looked just like that.

I guess there are two ways to tell, Does it smell like coolant? if not try a UV light, if it glows, then there is your answer.

Also, My old Suburban, had A/C and Heating lines that went to the back.. Don't no about the Ex.

It is freon dye. BUT it looks JUST like the coolant.

There are 4 lines:
one to the rear heater core
one from the rear heater core
one high pressure line from the front compressor to the rear evaporator(my leaky one)

one low pressure from the rear back to the front.

fixed it. cut the bad piece out of the line, flared it and used a brass coupler.

Total cost: $5.25+freon
