  Q: How to service the Air Inject Check Valve for Bank 2 on Chevrolet Lumina?

  A:

  Service of Air Inject Check Valve for bank 2 requires engine temperature to be low to avoid burns. The service starts with removing the clamp linked to the Air Hose from the check valve before proceeding to separate the vacuum line from the check valve. The right air pipe assembly must be removed from the manifold after disconnecting it from the Exhaust Manifold adaptors and removing the air pipe bracket nut. The check valve should be separated from the air pipe by removing its two bottom bolts. Upgrade the check valve by threading two bolts through the pipe before fitting the check valve with its associated pipe to the bracket stud and manifold adaptors while securely tightening the pipe connections to the manifold adaptors. Install the bracket stud nut followed by tightening of the locknut to 10 nm (88 lb in). The vacuum line installation should be performed by connecting it to the check valve while you reinstall the clamp and attach the Air Hose to its designated valve location.
