Detailed Product Description

Installation Notes and Tips

Confirm the vehicle uses an R134a refrigerant system before installation.

Replace the line only after recovering refrigerant and inspecting mating components for wear, corrosion, or contamination.

For best results, clean the connection points thoroughly and verify that the included seals and O-rings are seated correctly before charging the system. Fits 1995-1996 Dodge Ram 1500, hose assembly, and should be checked against the original routing and port location prior to final assembly.
