AC Help! 2.8 V6 Fiero (Page 1/1) stephenhawkins356 JUL 23, 05:35 PM I am working to undo a previous AC delete on a 1986 Fiero SE 2.8 V6. I have all of the necessary AC components except for the compressor and the compressor intake/discharge hose assembly (I'll include a picture too). I have located the hose assembly from a 1985 Fiero SE 2.5 L4. I cannot for the life of me find a part number to cross check them. Does anyone know if these hose assemblies are interchangeable from the 2.5 L4 to the 2.8 V6? Thanks in advance! RWDPLZ JUL 23, 07:51 PM They are not. You need a hose assembly for an 85-88 V6 car. The hose assemblies are almost specific to the year and engine size. There are differences between the V6 hose assemblies, but any year should work, IIRC the difference in the later years were just design improvements. For a part number to cross reference, try ACDelco 15-3484
