    Warning IconA warning icon, calling your attention to a possibly risky situation
    CAUTION
    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 instead.

Install

  1. Lubricate O-rings with the appropriate A/C oil. See Fluids and Capacities for A/C oil specifications. Then install the check valve into the supermanifold.
  2. Install a new evaporator check valve snap ring onto the supermanifold.
