I am sorry for the long wait
did you ask them if the GM lines are still available or if they are not is that why they need to splice them into place ?
Customer: replied 2 years ago.
As an ace mechanic you should know that the AC lines to the rear of the Suburban are aluminum and are on the outside of the truck, exposed to salt and other road hazards. Since it's a steel body and frame, the aluminum corrodes. My research shows that corrosion of these lines and the loss of coolant is common. I've already found and replaced the aluminum lines with high pressure rubber hoses specifically made for this application and problem. I don't require any additional help. thanks anyway.
