    How to Replace AC Expansion Valve and Condenser

    Replacing ac condenser. I got so into I forgot to take pics after a while. You do not need to remove the front bumper at all or hood latches. Have a professional vac out the system first.
    1) remove battery
    2 remove 90 degree intercooler tube
    3) remove upper radiator pipe
    4) remove fan shroud
    5) remove fan
    6) remove radiator brackets and push radiator back
    7) remove nut holding ac window
    8) remove under tray
    9) push condenser back.and unbolt brackets holding hard lines at the top (8mm)
    10) pry up hard line brackets
    11) condesor will move back farther now, remove passenger side high hard line from condenser
    12) remove bolt holding dryer bracket and slide off of tab (got to through the then rest through the big opening in bumper)
    13) remove lower hard line and the other hard line support above it.
    14) install new ac ac o-rings
    15) reassemble car
    16) fill with PAG 45 oil and R134 freeon.

    This took me about 4 hours, but that is because I was considering removing the front bumper when a neighbor pointed out the bracket holding the aAC window. This should take you much less time.

    Expansion Valve:
    1) Remove 2 Philip head screws at top of glove box
    2) Remove two lower 10 mm bolts at bottom of glove box
    3) Drop the box and disconnect the sensors
    4) Remove ac tubing
    5) Remove 3 metal brackets
    6) Remove ECU cover
    7) Remove bolts under the tray holding the core
    8) Remove white cover
    Under the hood
    9) Remove charcoal canister and it's bracket as one piece
    Note: Remove hose from inside the fender
    10) Disconnect two 10 mil bolts holding the lines. Then loose two 10 mil bolts holding black plate
    Back in the cabbin
    11) Just grab and pull the core out. The line will break free on their own
    12) Remove Allen head bolts holding the expansion valve to the core, and pull apart. Replace all o-rings with ac o-rings and reinstall.

    This took me about 3 hours, but I did not know I could just pull the core out. Without having to think or figure things out, this should take you much less time.

    Note: I do have pics of both processess, but hosting pics on this site is a pain. I do have the pics and instructions up on the supra facebook pages.
