These leaking lines are a pain in the butt. I've had my truck for less than 2 months now. Bought it with 26k on it. Had it a few days and noticed it leaking. The dealership changed the lower cooler line. Just had the upper line changed yesterday. Hopefully the new hoses will hold better. Once out of warranty, will put some better hoses on if I have more problems.
