Check Valve

  1. Inspect check valve whenever working on A.I.R. system. If pump was inoperative and had signs of exhaust gases reaching pump, a failed check valve would be indicated.
  2. After detaching valve, blow though it in direction of flow to cylinder head, then attempt to suck back through direction of flow. Replace valve if it allows airflow against direction of flow.
