Working on rear air

[roadlet_411]

Hi everyone, I'm new here and hoping you might be able to help me out with this. I just recently purchased a 2004 Yukon XL 1500 4wd with 76,*** miles. Got a good deal on it, but it comes with some issues. The A/C has a rear delete kit installed on it after they found a leak in the rear lines, so I ordered a set of the rubber replacement hoses to replace the leaky aluminum ones. Is there anything else I should go ahead and replace at the same time? Heat and the blower in the rear seem to work fine. Thanks ahead of time!

When I replaced my lines, my rear evap core was also F'ed up and had to be replaced. I would check it out and make sure its good before buttoning it all up.

Orifice tube, rear expansion valve, dryer/accumulator (make sure it has both ports for front and rear), 3lbs of refrigerant and 11oz of oil. Stop leak/UV dye is a good idea too. If you can replace the parts and go somewhere to pressurize the system to ensure there is no leaks first. Refrigerant is expensive.
