    • I am in need of changing the compressor on a 328.
    • The compressor is mounted on a mounting bracket that is secured to the engine block.
    • I understand the AC Compressor can be removed by lifting it through the engine compartment.
    • I understand the engine coolant pipe can stay installed.
    • The information I'm looking for is:
      • Does the whole assembly come out (Compressor and mounting bracket as an assembly) or does the Compressor come out by its self?
    • Any 'Heads Up' info is certainly appreciated.
    Thanks in advance.

    Oh, boy, you don't have enough four letter words for this job.

    1. Drain the coolant
    2. Remove the wheel and liner
    3. Remove air intake pipe from the body all the way to the air filter, and possibly remove the air filter housing
    4. Drain the coolant
    5. Remove the water pipe that goes from the water pump and then diving into the bottom of the car
    6. Remove the Alternator belt, the water pump belt, and then remove the AC belt
    7. Remove the bottom of the AC bracket
    8. Remove all the studs mounted to the engine / timing belt cover of bank 2 (forward bank). Double nutting does not work here. A proper stud puller is needed and then heat sometimes.
    9. Remove the STUDS at the top of the AC compressor that goes through the top bracket. Double nut method works here.
    10. Remove the hose fittings (2) and tie them out of the way
    11. Wiggle the compressor down, tilt, and out toward the top, after you disconnect the wires.
    12. Remove the rest of the bracket.
    13. Put the alternator belt back, and the water pump belt back
    14. Water pipe back, and fill it with coolant, and bleed.

    Was it worth it?

    Sounds like you might as well do a major service if you have one coming up.

    Removal of the AC compressor is 50% of the way to seeing the timing belts.

    My 328 GTB 1986 compressor has seized up, a/c not been used for years by previous owner(s).
    To much of a faff and expense to do now.
    I’ll wait for the engine out job before it’s replaced in a couple of years time.
    On hot sunny days I’ll be driving my F430 Spider anyway.

    It also depends on the compressor in the 328, Ferrari used two different types. The York compressor removal is as Mitchell described. The Sanden compressor is slightly easier, in that removing mounting studs isn’t necessary.
