  • 2024-06-19: Added step to make sure that the A/C system is depressurized before removing the cooled condenser check valve and added running ODIN routines through the touchscreen.

Remove

  1. Recover the refrigerant. See A/C Refrigerant (Recovery and Recharge).
  2. remove the coolant bottle. See Coolant Bottle (Remove and Replace).
  3. If not yet removed, remove the AC hoses from the vehicle.
  4. Carefully depress the Schrader valves (x2) to release the vacuum from the A/C lines.

    CAUTION
    Make sure to depress both Schrader valves. Failure to do so may result in injury.
  5. Remove and discard the liquid cooled condenser check valve snap ring from the supermanifold.
  6. Remove the liquid cooled condenser check valve from the supermanifold.

    Note
    If the check valve separates from the aluminum cap during removal, do not use metal tools. Metal tools may scrape the supermanifold housing causing internal damage. Use fingers or wrap electrical tape around a 90 degree pick.

Install

Installation procedure is the reverse of removal, except for the following:

  1. Before installing the liquid cooled condenser check valve into the supermanifold, use ND-11 oil to lubricate the O-rings.
