This kit is listed for applications using R134a and an orifice tube system, so the existing system should be inspected for debris, leaks, and contamination before reassembly. Always confirm the exact fitment by year, make, model, and compressor note, especially on Silverado, Sierra, Tahoe, and Yukon applications.
